Indicaciones (continuado)
BOTOX® también se inyecta en la piel para tratar los síntomas de la
sudoración severa en las axilas (hiperhidrosis axilar primaria severa)
cuando los medicamentos utilizados en la piel (tópicos) no funcionan lo
sufi cientamente bien en personas de 18 años y más.
No se sabe si BOTOX® es seguro o efectivo para otros tipos de espasmos
musculares o para la sudoración severa en otros lugares además de
las axilas.
BOTOX® Cosmetic es un medicamento recetado que se inyecta en los
músculos y se usa para mejorar el aspecto de arrugas moderadas a graves
del entrecejo (líneas acentuadas de expresión) en personas de 18 a 65
años de edad por un período corto de tiempo (temporal).

¿Qué es BOTOX ®?
Quizá ya ha oído hablar sobre BOTOX® Cosmetic (onabotulinumtoxinA). Pero como verá en este folleto, la historia de BOTOX® no es
sólo epidérmica.
BOTOX® (onabotulinumtoxinA) es una terapia efi caz que se ha utilizado para tratar pacientes durante aproximadamente 20 años. Uno de los
medicamentos más ampliamente investigados en el mundo, el tratamiento con BOTOX® es aprobado para uso médico en aproximadamente
75 paises.
Identifi cado por primera vez en la década de 1890, BOTOX® es una proteína purifi cada
que procede de la bacteria Clostridium botulinum. En aproximadamente 100 años, nuestro
conocimiento de la toxina botulínica tipo A se ha ampliado desde la identifi cación de la bacteria
C. botulinum hasta la comercialización de BOTOX® como el primer tratamiento aprobado con
toxina botulínica en los Estados Unidos.
En 1989, la neurotoxina de BOTOX® fue aprobada por la Administración de Fármacos y
Alimentos (Food and Drug Administration, FDA, por sus siglas en inglés) para el tratamiento
del blefaroespasmo (espasmos del párpado) y estrabismo (ojos cruzados
o desalineados). En el año 2000, la FDA aprobó BOTOX® para el
tratamiento de la rigidez muscular incontrolable o el giro del cuello, que
se conococe como la distonía cervical.
Otro hito en la historia de BOTOX® fue su aprobación en 2004 para
tratar la sudoración excesiva bajo los brazos cuando los agentes
tópicos no funcionan lo sufi cientemente bien. La misma fórmula con
la dosifi cación específi ca para tratar temporalmente las líneas de
expresión moderadas a graces entre las cejas en personas de 18 a 65
años de edad fue aprobada en 2002 como BOTOX® Cosmetic.

Todo fármaco aprobado por la FDA viene con la información sobre seguridad para los doctores y los pacientes. Las secciones
sombreadas en azul en este folleto contienen información sobre el tratamiento con BOTOX ®, así como información detallada sobre el
fármaco en sí. Si usted tiene preguntas o preocupación sobre cualesquiera de estas secciones por favor no dude en consultar
a su doctor.

BOTOX® (onabotulinumtoxinA) lo hace solamente Allergan—una compañía mundial especializada en dispositivos médicos y farmacéuticos que
ofrece innovadores productos en más de 100 países. El tratamiento con BOTOX® es producido bajo estrictos estándares de control de calidad
por Allergan y debe ser administrado a pacientes sólo por médicos con licencia.
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Llame a su doctor o busque ayuda médica de inmediato si tiene alguno de estos problemas en cualquier momento
(horas a semanas) después de la inyección de BOTOX® o BOTOX® Cosmetic:
• Propagación de los efectos de la toxina. El efecto de la toxina botulínica puede afectar zonas alejadas del lugar de la
inyección y provocar síntomas graves, incluyendo: pérdida de fuerza y debilidad muscular general, visión doble, visión borrosa
y párpados caídos, ronquera o cambio o pérdida de la voz (disfonía), problemas para decir las palabras con claridad (disartria),
pérdida de control de la vejiga, difi cultad para respirar, difi cultad para tragar
No se ha confi rmado ningún caso grave de propagación del efecto de la toxina lejos del lugar de la inyección cuando se ha usado
BOTOX® a la dosis recomendada para tratar sudoración intensa en las axilas, blefaroespasmo, o estrabismo, o cuando se ha
utilizado BOTOX® Cosmetic a la dosis recomendada para el tratamiento de las arrugas del entrecejo.

Como funciona el tratamiento con la neurotoxina BOTOX®
Cuando usted sufre de espasmos musculares, es porque sus células nerviosas están enviando señales directamente a los músculos, lo que
causa este efecto. El tratamiento con BOTOX® (onabotulinumtoxinA) funciona mediante el bloqueo de estas señales, lo que impide la liberación
de una sustancia conocida como acetilcolina.1 Demasiada acetilcolina hace que los músculos estén demasiado activos y tensos. Con la
neurotoxina BOTOX®, los espasmos musculares pueden cesar o disminuir1 signifi cativamente, lo cual proporciona alivio.
Usted también puede experimentar dolor de cuello asociado con la distonía cervical. Se cree que el BOTOX® funciona de manera similar para
bloquear las señales nerviosas que causan el dolor de cuello, lo que produce alivio. Hay evidencia de un estudio con pacientes que muestra
que el tratamiento con BOTOX® puede reducir en gran medida el dolor de cuello incluso antes de que disminuyan los espasmos musculares.2
La forma exacta en que funciona el BOTOX® en la reducción del dolor de cuello en la distonía cervical no es conocida.
Por favor consulte con su doctor cualquier pregunta que tenga sobre su tratamiento.
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
La dosis de BOTOX® no es la misma que, o comparable a, otro producto de toxina botulínica.
Se ha reportado reacciones alérgicas graves o inmediatas. Estas reacciones incluyen erupción cutánea con picazón,
hinchazón y difi cultad para respirar. Dígale a su médico o procure ayuda médica de inmediato si usted experimenta cualquiera de
estos síntomas; futuras inyecciones de BOTOX® o BOTOX® Cosmetic deben evitarse.

Las señales que pueden causar contracciones musculares y dolor de cuello llegan a los músculos a través de los nervios.
La neurotoxina de BOTOX® actúa en el músculo donde es inyectada para bloquear las señales que le indican al músculo que se contraiga y se cree que bloquea las señales que causan el dolor de cuello.
Como resultado, los espasmos musculares pueden detenerse o reducirse en gran medida, lo que produce un alivio que puede durar hasta 3 meses.1
BOTOX® funciona al hacer que los nervios no liberen acetilcolina, que es una sustancia que transmite señales de los nervios a los músculos.

Que puede esperar del tratamiento con BOTOX ®
Las inyecciones de BOTOX® serán
administradas en el consultorio médico.
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
No use BOTOX® o BOTOX® Cosmetic si usted: es alérgico a alguno de los ingredientes de BOTOX® o BOTOX® Cosmetic (véase
la Guía de Medicación para los ingredientes); ha tenido una reacción alérgica a cualquier producto de toxina botulínica tales como
Myobloc ® o Dysport ®; tiene una infección en la piel en el sitio previsto de la inyección.
Una vez que usted y su doctor han determinado que BOTOX® (onabotulinumtoxinA) es para usted, su tratamiento consistirá en una serie
de inyecciones en los músculos seleccionados por su doctor. Las inyecciones de BOTOX® serán administradas en el consultorio médico. La
cantidad de BOTOX® y los puntos de inyección dependerán de sus necesidades. Usted podría experimentar dolor, infección, infl amación,
sensibilidad, hinchazón, enrojecimiento y/o sangrado/moretones en los puntos de inyección.
Dado que la neurotoxina BOTOX® es inyectada directamente en los músculos afectados, no se espera que esté presente en el torrente
sanguíneo después de la inyección en la dosis recomendada. Usted debería ser capaz de dejar el consultorio de su doctor después de un
período corto de recuperación.
¿Cuánto tardan en verse los resultados? No mucho. Podría empezar a ver la mejoría en los
síntomas a los pocos días (unas pocas semanas en algunas afecciones) de haber recibido el
tratamiento con BOTOX® y quizá no tenga que volver a consulta para recibir otra inyección en
hasta 3 meses.1

¿Duele el tratamiento con BOTOX®?
El tratamiento con BOTOX® (onabotulinumtoxinA) se administra con agujas muy fi nas, de manera que la mayoría de la gente siente sólo un
leve malestar. No es común requerir alivio del dolor, aunque algunos doctores sugieren el uso de una crema de anestesia tópica antes
del tratamiento.
¿BOTOX® Cosmetic es igual a la neurotoxina BOTOX®?
Sí. BOTOX® Cosmetic y BOTOX® tienen la misma formulación. La neurotoxina BOTOX® es uno de los medicamentos más ampliamente
investigados en el mundo y ha sido utilizada durante aproximadamente 20 años. La misma formulación con dosis específi cas para el
tratamiento temporal de las arrugas del entrecejo de moderadas a graves (líneas acentuadas de expresión entre las cejas) para las
personas de edades comprendidas entre 18 y 65 años fue aprobada en 2002 como BOTOX® Cosmetic (onabotulinumtoxinA).
¿Es seguro recibir repetidas inyecciones de BOTOX®?
El tratamiento con BOTOX® está aprobado por la FDA para varias inyecciones. En la mayoría de los pacientes el tratamiento con BOTOX®
suele durar hasta 3 meses1—y se puede repetir siempre y cuando el paciente siente alivio de los síntomas y no tenga reaciones alérgicas
graces u otros efectos secundarios relacionados con BOTOX®. Su doctor determinará el momento apropiado para volver a aplicar la inyección.
Pacientes de todo el mundo reciben inyecciones repetidas de la neurotoxina BOTOX® para tratar con efi cacia una variedad de condiciones
médicas (distonía cervical, blefaroespasmo, y estrabismo).
Preguntas frecuentes sobre el tratamiento con BOTOX ®
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Dígale a su doctor acerca de todas sus condiciones de músculos o nervios tales como la esclerosis lateral amiotrófi ca
[ALS o enfermedad de Lou Gehrig], miastenia gravis o síndrome de Lambert-Eaton, ya que podría estar en mayor riesgo de efectos
secundarios graves, incluyendo disfagia severa (difi cultad para tragar) y compromiso respiratorio (difi cultad para respirar) de dosis
típicas de BOTOX® o BOTOX® Cosmetic.

¿Es cierto que algunos pacientes no siempre tienen la misma respuesta a repetidas inyecciones de BOTOX®?
Hay muchos factores que impactan los resultados del tratamiento con BOTOX®. Un porcentaje muy pequeño desarrolla inmunidad
al BOTOX®. Otros factores que impactan los resultados incluyen la precisión de las inyecciones, la dosifi cación, y los cambios en las
afecciones de los pacientes con el tiempo.
Existen otras toxinas botulínicas disponibles. ¿Son iguales al tratamiento de BOTOX®?
Es importante entender que no hay dos productos de toxinas botulínicas iguales. Se diferencian en su dosis, proceso de fabricación,
potencia, y efectos adversos. Como resultado, cada producto y su unidad de dosifi cación son únicos y diferentes, y un producto no
puede reemplazar el otro.
¿Cómo se sabe que se está recibiendo el tratamiento con BOTOX® y no con un producto sucedáneo?
BOTOX® es una marca registrada de Allergan, Inc. El producto BOTOX® está empacado en una ampolla de vidrio con tapa violeta o naranja
etiquetada como BOTOX ® y tiene un holograma de Allergan a un lado. Quizá quiera usted pedirle a quien lo va a inyectar que le confi rme
que BOTOX® es el producto a usar en su tratamiento.

Distonía cervical y el tratamiento con BOTOX ® (onabotulinumtoxin A)
Definición y síntomas de la distonía cervical
La distonía cervical es una afección que hace que los músculos del cuello se tensen o sufran espasmos incontrolables.3,4 Si usted tiene distonía
cervical, su cabeza puede torcerse de manera fuera de lo común, o puede ser forzada a una postura anormal. Los síntomas pueden difi cultar el
desempeño de las sencillas tareas diarias como vestirse o manejar un auto. Pero la distonía cervical puede ser tratada. El obtener tratamiento
puede ayudarle a volver a las actividades que usted disfrutaba antes que comenzaron los síntomas.
El primer paso para sentirse mejor es plantearle sus síntomas a su doctor. Las señales comunes de la distonía cervical a menudo varían de
persona a persona y pueden incluir cualquiera de las siguientes combinaciones:
■ Espasmos musculares o rigidez4,5
■ Jalones o tirantez incómoda en el cuello5,6 o voltear de la cabeza5,7
■ Dolor de cuello (reportado en hasta 91% de los pacientes)8
■ Dolor alrededor del cuello que empeora con el tiempo7
■ Temblores en la cabeza o la mano5-7
■ Síntomas que van aumentando hasta involucrar partes adyacentes del cuerpo9
Si sospecha que tiene distonía cervical, consulte a su doctor.

“Todo comenzó con un dolor en la base de mi cuello. Entonces mi cuello
comenzó a jalarse y sacudirse cuando traté de enderezarlo. Fue difícil.
Luchaba con esto todos los días. Estaba en guerra con mi cuello.”
Gus, paciente con distonía cervical
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Dígale a su doctor acerca de todos los medicamentos que toma, incluyendo medicamentos con receta y sin receta,
vitaminas, y productos herbarios.
BOTOX® y BOTOX® Cosmetic pueden causar pérdida de fuerza o debilidad muscular general, o problemas de visión. Si estoocurre,

Diagnóstico de la distonía cervical
El diagnóstico de la distonía cervical puede ser un reto, en especial en sus fases iniciales o leves. Esto es porque los síntomas pueden ser
leves al inicio y diferir de persona a persona. La distonía cervical a veces es diagnosticada incorrectamente porque se asemeja a otras
dolencias físicas como cuello rígido o estrés. En algunos casos, los pacientes podrían sufrir distonía cervical durante un año o más antes de
ser diagnosticados o tratados.7
Para el diagnóstico de la distonía cervical se pueden usar diversas pruebas como imágenes del cerebro, exámenes de sangre,
electroencefalografías (EEG, por sus siglas en inglés), electromiografías (EMG, por sus siglas en inglés), y monitoreo por video. Una evaluación
también podría incluir pruebas genéticas en algunas situaciones.4 Estas pruebas pueden ser usadas para descartar otras afecciones, dejando
la distonía cervical como el diagnóstico.
Para proporcionar información adicional que pueda ayudar a los doctores a diagnosticar la distonía cervical, los expertos en trastornos del
movimiento han desarrollado estas sencillas preguntas10:
■ ¿Siente usted que su cabeza gira, se inclina o se desplaza en alguna dirección?
■ ¿Se sacude o se agita su cabeza?
■ ¿Sus hombros se levantan o se mueven hacia arriba o hacia abajo sin control?
■ ¿Le han dicho otras personas que su cabeza se mueve hacia los lados, hacia adelante o hacia atrás?
■ ¿Le han dicho otras personas que la cabeza le tiembla?
■ ¿Tiene algún dolor o rigidez en el cuello la mayor parte del tiempo?
■ ¿Hay alguna posición en la que usted puede poner su cabeza para hacer que el movimiento o el dolor cesen?
■ ¿Alguna vez ha consultado a un doctor acerca de los giros o temblores de la cabeza?

La distonía cervical es una enfermedad progresiva
La distonía cervical es una enfermedad progresiva lo que signifi ca que los síntomas pueden empeorar con el tiempo. En aproximadamente
20% de las personas los síntomas de distonía cervical desaparecen completamente.9 Esto se conoce como remisión. Sin embargo, es
importante entender que los síntomas a menudo retornan.9 Normalmente para la mayoría de la gente con distonía cervical los síntomas
dejan de empeorar después 5 años9
Son muchas las causas de la distonía cervical: accidentes, herencia, o causas desconocidas. Para más información, consulte a su médico.
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)

Tipos de distonía cervical
La distonía cervical causa tensión muscular constante—ésta es la parte de la distonía—y esto ocurre principalmente en el área del cuello,
en lo que se llama la columna cervical. Los músculos tensos en el cuello jalan la cabeza con movimientos y hacia posturas anormales.
Hay 4 tipos principales de distonía cervical, defi nida por la inclinación de la cabeza:
La mayoría de los pacientes (hasta un 81%) tienen una combinación de estas tres posturas.5 Por ejemplo, la cabeza puede verse halada en
2 o más direcciones a la vez, como hacia adelante y hacia un lado.5 La distonía cervical también puede ser llamada espasmódica, si hay
contracciones musculares involuntarias repentinas, o sostenida, si la tensión muscular es contínua.4

Distonía cervical y el tratamiento con BOTOX ®(onabotulinumtoxinA) (continuado)Tratamientos para la distonía cervical
Los doctores cuentan con un número de opciones para tratar la distonía cervical. El tratamiento más comúnmente escogido es con la
neurotoxina BOTOX® (onabotulinumtoxinA). BOTOX® es considerada la terapia de primera línea para la distonía cervical,11 lo cual quiere decir
que los doctores pueden escoger el usar directamente a la neurotoxina BOTOX®, sin tratar otras opciones. Su médico determina exactamente
cuáles músculos le están causando problemas y les inyecta la neurotoxina BOTOX®.
El BOTOX® se utiliza a menudo en combinación con la terapia física. También pueden usarse medicamentos orales. La cirugía en los nervios
implicados también puede ser una opción, pero se utiliza muy poco, ahora que la neurotoxina BOTOX® está disponible.4
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Llame a su doctor o busque ayuda médica de inmediato si tiene alguno de estos problemas en cualquier momento
(horas a semanas) después de la inyección de BOTOX® y BOTOX® Cosmetic:
• Propagación de los efectos de la toxina. El efecto de la toxina botulínica puede afectar zonas alejadas del lugar de la
inyección y provocar síntomas graves, incluyendo: pérdida de fuerza y debilidad musuclar general, visión doble, visión borrosa
y párpados caídos, ronquera o cambio o pérdida de la voz (disfonía), problemas para decir las palabras con claridad (disartria),
pérdida de control de la vejiga, difi cultad para respirar, difi cultad para tragar
No se ha confi rmado ningún caso grave de propagación del efecto de la toxina lejos del lugar de la inyección cuando se ha usado
BOTOX® a la dosis recomendada para tratar sudoración intensa en las axilas, blefaroespasmo, o estrabismo, o cuando se ha
utilizado BOTOX® Cosmetic a la dosis recomendada para el tratamiento de las arrugas del entrecejo.
La dosis de BOTOX® no es la misma que, o comparable a, otro producto de toxina botulínica.

Como puede ayudar BOTOX®
Para la mayoría de la gente con distonía cervical, las inyecciones de BOTOX® (onabotulinumtoxinA) son muy efi caces. La terapia con BOTOX®
detiene o reduce de gran manera el dolor de cuello y los espasmos musculares. Los resultados de un estudio clínico clave mostraron que
después de recibir inyecciones de la neurotoxina BOTOX®, los pacientes con
distonía cervical habían mejorado la postura de la cabeza, sentían un dolor menos
intenso y frecuente, y tenían mejor capacidad para funcionar en ciertas actividades
diarias.7 Otro estudio mostró que puede haber alivio del dolor aún antes de que los
músculos se relajen de manera signifi cativa.2
Todos estos son benefi cios importantes para personas con distonía cervical. Para
muchos, las inyecciones de BOTOX® pueden ser un tratamiento efi caz para la
distonía cervical. Después de un tratamiento con la neurotoxina BOTOX®, muchos
pacientes con distonía cervical pasan hasta 3 meses de alivio de los espasmos
musculares.1 Esto es lo que tarda a los nervios el reanudar la liberación
de acetilcolina.
www.BOTOXMedical.com
Con el tratamiento con BOTOX ® muchos pacientes con distonía cervical obtienen alivio en los músculos del cuello demasiado activos
o tensos. BOTOX ® también puede disminuir el dolor de cuello asociado con la distonía cervical, incluso antes de que reduzcan
considerablemente los espasmos musculares.
Aqui encontrará lo que la neurotoxina de BOTOX® puede hacer para usted:
■ Detener o reducir en gran medida el dolor de
cuello y los espasmos musculares
■ Mejorar la postura de la cabeza
■ Reducir la intensidad y la frecuencia del dolor
de cuello
■ Mejorar su capacidad para realizar ciertas
actividades cotidianas

Vivir con distonía cervical—consejos para pacientes
Además de tomar sus medicamentos y seguir los consejos de su doctor, hay otras cosas que puede hacer para ayudar a aliviar los síntomas
de la distonía cervical:
■ Evite el estrés en el trabajo, en lugares públicos, o en el hogar
– Es importante entender que el estrés puede exacerbar los síntomas de distonía cervical 12
■ Asegúrese de obtener sufi ciente tiempo de relajación12
■ Coma con sensatez y nutricionalmente
– Evite los alimentos que estimulen los nervios. La cafeína, el azúcar, y el chocolate pueden a veces
activar los síntomas de la distonía cervical 12
■ Consulte a su doctor en cuanto al programa de ejercicio
– Yoga ligera, calistenia simple, ejercicio en el agua, y ejercicios de respiración profunda que puedan
ayudar a relajar tanto a la mente como al cuerpo 12
■ Conéctese con grupos de apoyo en su área para obtener recursos adicionales y educación (algunos están enumerados en la parte
posterior de este folleto)
Si su doctor decide que debe ser tratado para la distonía cervical, asegúrese de hacer un seguimiento de cualquier mejora o empeoramiento
de sus síntomas, así como su reacción al tratamiento. Comparta todas sus observaciones con su doctor y sea un colaborador activo en la
gestión de su distonía cervical.

He aquí un ejercicio sensorial que usted quizá quisiera probar...
La distonía cervical es la distonía focal más común que responde a trucos sensoriales. Por ejemplo: los pacientes con distonía cervical
pueden ponerse la mano a un lado de la cara, barbilla, o detrás de la cabeza. Esto puede ayudar a reducir la intensidad de los síntomas.
El tocar o aplicar leve presión en ciertas áreas de la cabeza—en el lado opuesto al cual la cabeza gira—puede temporalmente permitir
la corrección de la posición anormal de la cabeza.
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Dígale a su doctor acerca de todas sus condiciones de músculos o nervios tales como la esclerosis lateral amiotrófi ca
[ALS o enfermedad de Lou Gehrig], miastenia gravis, o síndrome de Lambert-Eaton, ya que podría estar en mayor riesgo de efectos
secundarios graves, incluyendo disfagia severa (difi cultar para tragar) y compromiso respiratorio (difi cultar para respirar) de dosis
típicas de BOTOX® o BOTOX® Cosmetic.
Dígale a su doctor acerca de todas sus afecciones médicas, incluso si usted tiene: planes de someterse a una cirugía,
ha tenido una cirugía en el rostro; debilidad de los músculos de la frente, como problemas para levantar las cejas; párpados
caídos; cualquier otro cambio anormal del rostro; está embarazada o piensa quedar embarazada (no se sabe si BOTOX® o BOTOX®
Cosmetic puede dañar a su bebe no nacido); está dando pecho o planea dar pecho (no se sabe si BOTOX® o BOTOX® Cosmetic se
excreta en la leche materna).

El blefaroespasmo y el tratamiento con BOTOX ®
Definición y síntomas del blefaroespasmo
El blefaroespasmo es un trastorno muscular caracterizado por espasmos
musculares involuntarios de los músculos alrededor del ojo, lo que resulta
en un estrechamiento incontrolable o en el cierre del párpado.13,14 Una
consecuencia grave del blefaroespasmo es el deterioro de la visión.
En algunos pacientes, el cierre forzado de los párpados se vuelve tan
grave que hacer las cosas simples como conducir un auto o usar una
computadora se convierten en un reto. Aproximadamente 65% de la gente
con blefaroespasmo son mujeres y la edad promedio del inicio es 56 años
de edad.14
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Dígale a su doctor acerca de todos los medicamentos que toma, incluyendo medicamentos con receta y sin receta,
vitaminas, y productos herbarios.
BOTOX® y BOTOX® Cosmetic pueden causar pérdida de fuerza o debilidad muscular general, o problemas de visión. Si esto
ocurre, no conduzca un automóvil, opere maquinaria o realice otras actividades peligrosas.

www.BOTOXMedical.com
Diagnóstico del blefaroespasmo
Los doctores diagnostican el blefaroespasmo basado en signos y síntomas
claves. En los estados iniciales del blefaroespasmo, los pacientes pueden
quejarse de irritación e incomodidad de los párpados además de aumento
en el parpadeo.13,14
A medida que el blefaroespasmo progresa, el parpadeo usualmente se vuelve
más frecuente, enérgico, e incontrolable. La luz brillante, el ruido, el estrés,
el aire contaminado, o el viento pueden empeorar los síntomas.15 Sin el
tratamiento medico apropiado pocos pacientes con blefaroespasmo mejoran
por su cuenta.14
Como puede ayudar el tratamiento con BOTOX ®
La neurotoxina BOTOX® (onabotulinumtoxinA) ha sido el tratamiento principal para el blefaroespasmo desde la aprobación de la FDA en 1989.
Las inyecciones de BOTOX® se administran directamente en el sitio de acción. Cuando es inyectado directamente en los músculos afectados
alrededor del ojo, la neurotoxina afl oja el espasmo muscular y el cerrar a la fuerza involuntariamente del párpado. El tratamiento con BOTOX®
se puede repetir aproximadamente cada 3 meses mientras el paciente continúa respondiendo y no tiene una reacción alérgica.1
Entre los primeros síntomas del blefaroespasmo pueden estar 14:
■ Ojos secos o llorosos
■ Sensibilidad a la luz
■ Aumento del parpadeo
■ Dolor ocular■ Irritación

El estrabismo y el tratamiento con BOTOX ®
Definición y síntomas del estrabismo
Estrabismo es el nombre que los doctores le dan a un grupo de afecciones
en las cuales los músculos se tensan alrededor del ojo lo que resulta en
que se jala el globo ocular hacia un lado. También se conoce al estrabismo
como ojos cruzados. Una forma común es la esotropía, o estrabismo
convergente, que es cuando uno o ambos ojos miran hacia la nariz.15
Entre otros síntomas se encuentran el ladeo de la cabeza para ver cosas,
movimientos frecuentes de los ojos, dolor de cabeza, frotamiento de los
ojos, lagrimeo, y visión doble.
Hoy en día, el estrabismo se trata típicamente en la infancia temprana
(antes de los 4 a 6 años de edad) con entrenamiento ortóptico (ejercicios
de los ojos), anteojos, y/o lentes de contacto.15 En algunos casos en los que
las técnicas de fortalecimiento no tienen éxito, quizá se requiera realinear
los músculos oculares mediante cirugía.15
INFORMACIÓN IMPORTANTE DE SEGURIDAD (continuado)
Otros efectos secundarios de BOTOX® y BOTOX® Cosmetic incluyen: boca seca, molestias o dolor en el sitio de la inyección,
cansancio, dolor de cabeza, dolor de cuello, y problemas oculares: visión doble, visión borrosa, disminución de la visión, párpados
caídos, hinchazón de los párpados, y sequedad en los ojos.
Para obtener información adicional consulte la Guía del Medicamento o hable con su médico.
Le animamos a que reporte efectos secundarios negativos de los medicamentos recetados a la FDA.

www.BOTOXMedical.com
El estrabismo en adultos con frecuencia se diagnostica en aquellos pacientes que no fueron tratados o que fueron tratados sin éxito durante
la infancia.16 También hay algunos adultos que desarrollan estrabismo debido a una enfermedad o un traumatismo, lo cual suele dar lugar a
visión doble o una limitación en su percepción de la profundidad o del campo de visión (visión periférica y lateral).16
Diagnóstico del estrabismo
Cuando ocurre en niños, los padres son los primeros en notarlo o los doctores porque los ojos de los niños aparecen en posición anormal. Un
examen ocular confi rma el diagnóstico e identifi ca el tipo de estrabismo.
El estrabismo nunca debe ser ignorado bajo la presunción de que al crecer el niño se le pasará. A menos que sea tratado antes de los 4 a 6
años de edad, el estrabismo puede llevar a una pérdida de la visión permanente en el ojo desviado.15
Como puede ayudar el tratamiento con BOTOX ®
En el tratamiento del estrabismo, se cree que sólo el tratamiento con BOTOX® (onabotulinumtoxinA) tiene un efecto sobre los pares de
músculos. Al ser inyectados con la neurotoxina BOTOX®, los músculos se debilitan y los espasmos se reducen ligeramente. Esto permite que
los músculos del otro lado del ojo se contraigan.1 A través de esta doble acción, el tratamiento con BOTOX® se piensa que ayuda a alinear los
ojos, o a que miren en la misma dirección.

FULL PRESCRIBING INFORMATION
Distant Spread of Toxin EffectPostmarketing reports indicate that the effects of BOTOX and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have underlying conditions that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and at lower doses.

5 WARNINGS AND PRECAUTIONS
5.1 Lack of Interchangeability between Botulinum Toxin Products The potency Units of BOTOX are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see Description (11)].
5.2 Spread of Toxin EffectPostmarketingsafetydatafromBOTOXandotherapprovedbotulinumtoxinssuggestthatbotulinumtoxineffectsmay,insomecases,beobservedbeyondthesiteoflocalinjection.Thesymptomsareconsistentwiththemechanismofactionofbotulinumtoxinandmayincludeasthenia,generalizedmuscleweakness,diplopia,ptosis,dysphagia,dysphonia,dysarthria,urinaryincontinence,andbreathingdifficulties.Thesesymptomshavebeen reportedhours toweeksafter injection.Swallowingandbreathingdifficulties canbe life threatening and there havebeen reports of death related to spreadof toxin effects.The risk ofthe symptoms is probably greatest in children treated for spasticity but symptoms can also occur inadultstreatedforspasticityandotherconditions,andparticularlyinthosepatientswhohaveunderlyingconditions thatwould predispose them to these symptoms. In unapproveduses, including spasticity inchildren,andinapprovedindications,symptomsconsistentwithspreadoftoxineffecthavebeenreportedatdosescomparabletoorlowerthandosesusedtotreatcervicaldystonia.

Treatment of cervical dystonia with botulinum toxins may weaken neck muscles that serve asaccessorymusclesofventilation.Thismayresultinacriticallossofbreathingcapacityinpatientswithrespiratorydisorderswhomayhavebecomedependentupontheseaccessorymuscles.Therehavebeenpostmarketing reportsof seriousbreathingdifficulties, including respiratory failure, in cervicaldystoniapatients.
Patients with smaller neck muscle mass and patients who require bilateral injections into thesternocleidomastoidmuscle have been reported to be at greater risk for dysphagia. Limiting the doseinjectedintothesternocleidomastoidmusclemayreducetheoccurrenceofdysphagia.Injectionsintothelevatorscapulaemaybeassociatedwithanincreasedriskofupperrespiratoryinfectionanddysphagia.

7 DRUG INTERACTIONS
NoformaldruginteractionstudieshavebeenconductedwithBOTOX(onabotulinumtoxinA)forinjection.
Co-administration of BOTOX and aminoglycosides or other agents interfering with neuromusculartransmission(e.g.,curare-likecompounds)shouldonlybeperformedwithcautionastheeffectofthetoxinmaybepotentiated.
UseofanticholinergicdrugsafteradministrationofBOTOXmaypotentiatesystemicanticholinergiceffects.
The effect of administering different botulinum neurotoxin products at the same time or within severalmonths of each other is unknown. Excessive neuromuscular weakness may be exacerbated byadministrationofanotherbotulinumtoxinpriortotheresolutionoftheeffectsofapreviouslyadministeredbotulinumtoxin.
Excessive weaknessmay also be exaggerated by administration of a muscle relaxant before or afteradministrationofBOTOX.

10 OVERDOSAGE
ExcessivedosesofBOTOX(onabotulinumtoxinA)forinjectionmaybeexpectedtoproduceneuromuscularweakness with a variety of symptoms. Respiratory support may be required where excessivedoses cause paralysis of respiratory muscles. In the event of overdose, the patient should bemedically monitored for symptoms of excessive muscle weakness or muscle paralysis [see Boxed Warning and Warnings and Precautions (5.2, 5.4)].Symptomatictreatmentmaybenecessary.
Symptoms of overdose are likely not to be present immediately following injection. Should accidentalinjectionororal ingestionoccur, thepersonshouldbemedicallysupervisedforseveralweeksforsignsandsymptomsofexcessivemuscleweaknessorparalysis.

11 DESCRIPTION
BOTOX (onabotulinumtoxinA) for injection is a sterile, vacuum-dried purified botulinum toxin type A,produced from fermentationofHallstrainClostridiumbotulinum typeA,and intended for intramuscularandintradermaluse.Itispurifiedfromtheculturesolutionbydialysisandaseriesofacidprecipitationstoacomplexconsistingoftheneurotoxin,andseveralaccessoryproteins.ThecomplexisdissolvedinsterilesodiumchloridesolutioncontainingAlbuminHumanandissterilefiltered(0.2microns)priortofillingandvacuum-drying.

BOTOX® Cosmetic (onabotulinumtoxinA)for injection
Manufacturedby:AllerganPharmaceuticalsIreland asubsidiaryof:Allergan,Inc.2525DupontDr.,Irvine,CA92612
Distant Spread of Toxin EffectPostmarketingreportsindicatethattheeffectsofBOTOX® Cosmetic and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, blurred vision, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms havebeenreportedhourstoweeksafterinjection.Swallowingandbreathingdifficultiescanbelife threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have underlying conditions that would predispose them to these symptoms. In unapproved uses, including spasticity in children and adults, and in approved indications, cases of spread of effect have occurred at doses comparable to those used to treat cervical dystonia and at lower doses.
DESCRIPTION
BOTOX® Cosmetic (onabotulinumtoxinA) for injection, is a sterile, vacuum-dried purified botulinum toxin type A, produced from fermentation of Hall strain Clostridium botulinum type A grown in a medium containing casein hydrolysate, glucose, and yeast extract, intended for intramuscular use. It is purified from the culture solution by dialysis and a series of acid precipitations to a complex consisting of the neurotoxin, and several accessory proteins. The complex is dissolved in sterile sodium chloride solution containing Albumin Human and is sterile filtered(0.2microns)priortofillingandvacuum-drying.
One Unit of BOTOX® Cosmetic corresponds to the calculated median intraperitoneal lethal dose (LD50)inmice.ThemethodutilizedforperformingtheassayisspecifictoAllergan’sproduct, BOTOX® Cosmetic. Due to specific details of this assay such as the vehicle, dilution scheme and laboratory protocols for the various mouse LD50 assays, Units of biological activity of BOTOX® Cosmetic cannot be compared to nor converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method. In addition, differences in species sensitivities to different botulinum neurotoxin serotypes precludes extrapolation of animal-dose activity relationships to human dose estimates. The specific activity of BOTOX® Cosmetic isapproximately20Units/nanogramofneurotoxin protein complex.
Each vial of BOTOX® Cosmetic containseither100UnitsofClostridium botulinum type A neurotoxincomplex,0.5mgofAlbuminHuman,and0.9mgofsodiumchlorideor50Unitsof Clostridium botulinumtypeAneurotoxincomplex,0.25mgofAlbuminHuman,and0.45mgof sodium chloride in a sterile, vacuum-dried form without a preservative.
CLINICAL PHARMACOLOGY
BOTOX® Cosmetic blocks neuromuscular transmission by binding to acceptor sites on motor nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibitionoccursastheneurotoxincleavesSNAP-25,aproteinintegraltothesuccessful dockingandreleaseofacetylcholinefromvesiclessituatedwithinnerveendings.Wheninjectedintramuscularly at therapeutic doses, BOTOX® Cosmetic produces partial chemical denervation of the muscle resulting in a localized reduction in muscle activity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX® Cosmetic.
Pharmacokinetics
Using currently available analytical technology, it is not possible to detect BOTOX® Cosmetic in the peripheral blood following intramuscular injection at the recommended doses.
CLINICAL STUDIES
Glabellar Lines
Twophase3randomized,multi-center,double-blind,placebo-controlledstudiesofidentical design were conducted to evaluate BOTOX® Cosmetic for use in the temporary improvement of the appearance of moderate to severe glabellar facial lines. The studies enrolled healthy adults (ages18to75)withglabellarlinesofatleastmoderateseverityatmaximumfrown.Patients were excluded if they had ptosis, deep dermal scarring, or an inability to substantially lessen glabellarlinesevenbyphysicallyspreadingthemapart.SubjectsreceivedasingletreatmentwithBOTOX® Cosmetic(N=405,combinedstudies)orplacebo(N=132,combinedstudies).Injection volumewas0.1mL/injectionsite,foradose/injectionsiteintheactivetreatmentgroupsof4 Units.Subjectswereinjectedintramuscularlyinfivesites,1intheprocerusmuscleand2ineachcorrugatorsuperciliimuscle,foratotaldoseintheactivetreatmentgroupsof20Units.

INDICATIONS AND USAGE
BOTOX® Cosmetic is indicated for the temporary improvement in the appearance of moderate to severe glabellarlinesassociatedwithcorrugatorand/orprocerusmuscleactivityinadultpatients ≤65yearsofage.
CONTRAINDICATIONS
BOTOX® Cosmeticiscontraindicatedinthepresenceofinfectionattheproposedinjectionsite(s) and in individuals with known hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation.
WARNINGS
BOTOX® and BOTOX® Cosmetic contain the same active ingredient in the same formulation. Therefore, adverse events observed with the use of BOTOX® also have the potential to be associated with the use of BOTOX® Cosmetic.
The recommended dosage and frequency of administration for BOTOX® Cosmetic should not be exceeded. Risks resulting from administration at higher dosages are not known.
Lack of Interchangeability between Botulinum Toxin Products
The potency Units of BOTOX® Cosmetic are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX® Cosmetic cannot be compared to or converted into units of any other botulinum toxin products assessed with any other specific assay method (see DESCRIPTION).
Spread of Toxin Effect
PostmarketingsafetydatafromBOTOX® Cosmetic and other approved botulinum toxins suggest that botulinum toxin effects may, in some cases, be observed beyond the site of local injection. The symptoms are consistent with the mechanism of action of botulinum toxin and may include asthenia, generalized muscle weakness, diplopia, blurred vision, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms have been reported hourstoweeksafterinjection.Swallowingandbreathingdifficultiescanbelifethreatening and there have been reports of death related to spread of toxin effects. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, and particularly in those patients who have underlying conditions that would predispose them to these symptoms. In unapproved uses, including spasticity in children and adults, and in approved indications, symptoms consistent with spread of toxin effect have been reported at doses comparable to or lower than doses used to treat cervical dystonia.

Nodefinitiveseriousadverseeventreportsofdistantspreadoftoxineffectassociatedwith BOTOX®forblepharospasmattherecommendeddose(30Unitsandbelow)orforstrabismusat the labeled doses have been reported.
Hypersensitivity Reactions
Seriousand/orimmediatehypersensitivityreactionshavebeenreported.Thesereactionsincludeanaphylaxis, urticaria, soft tissue edema, and dyspnea. If such a reaction occurs, further injection of BOTOX® Cosmetic should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was used as the diluent, and consequently the causal agent cannot be reliably determined.
Pre-Existing Neuromuscular Disorders
Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis, or neuromuscularjunctionaldisorders(e.g.,myastheniagravisorLambert-Eatonsyndrome)should bemonitoredparticularlycloselywhengivenbotulinumtoxin.Patientswithneuromuscular disorders may be at increased risk of clinically significant effects including severe dysphagia and respiratory compromise from typical doses of BOTOX® Cosmetic(seeADVERSE REACTIONS).
Dysphagia and Breathing Difficulties in Treatment of Cervical Dystonia
Treatment with BOTOX® and other botulinum toxin products can result in swallowing or breathing difficulties.Patientswithpre-existingswallowingorbreathingdifficultiesmaybemoresusceptibleto these complications. In most cases, this is a consequence of weakening of muscles in the area of injectionthatareinvolvedinbreathingorswallowing.Whendistanteffectsoccur,additionalrespiratorymusclesmaybeinvolved(seeWARNINGS).
Deaths as a complication of severe dysphagia have been reported after treatment with botulinum toxin. Dysphagia may persist for several months, and require use of a feeding tube to maintain adequate nutrition and hydration. Aspiration may result from severe dysphagia and is a particular risk when treating patients in whom swallowing or respiratory function is already compromised.
Treatment of cervical dystonia with botulinum toxins may weaken neck muscles that serve as accessory muscles of ventilation. This may result in a critical loss of breathing capacity in patients with respiratory disorders who may have become dependent upon these accessory muscles. There have been postmarketing reports of serious breathing difficulties, including respiratory failure, in cervical dystonia patients.
Patientstreatedwithbotulinumtoxinmayrequireimmediatemedicalattentionshouldthey develop problems with swallowing, speech, or respiratory disorders. These reactions can occurwithinhourstoweeksafterinjectionwithbotulinumtoxin(seeWARNINGS, ADVERSE REACTIONS, CLINICAL PHARMACOLOGY).
Cardiovascular System
There have been reports following administration of BOTOX® of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Someofthesepatientshadriskfactorsincludingpre-existingcardiovasculardisease.

PRECAUTIONS
The safe and effective use of BOTOX® Cosmetic depends upon proper storage of the product, selectionofthecorrectdose,andproperreconstitutionandadministrationtechniques.Physiciansadministering BOTOX® Cosmeticmustunderstandtherelevantneuromuscularand/ororbital anatomy of the area involved, as well as any alterations to the anatomy due to prior surgical procedures and avoid injection into vulnerable anatomic areas.
CautionshouldbeusedwhenBOTOX® Cosmetic treatment is used in the presence of inflammationattheproposedinjectionsite(s)orwhenexcessiveweaknessoratrophyispresent inthetargetmuscle(s).
Reduced blinking from BOTOX® Cosmetic injection of the orbicularis muscle can lead to corneal exposure, persistent epithelial defect and corneal ulceration, especially in patients with VII nerve disorders. In the use of BOTOX® for the treatment of blepharospasm, one case of corneal perforation in an aphakic eye requiring corneal grafting has occurred because of this effect. Carefultestingofcornealsensationineyespreviouslyoperatedupon,avoidanceofinjectioninto the lower lid area to avoid ectropion, and vigorous treatment of any epithelial defect should be employed. This may require protective drops, ointment, therapeutic soft contact lenses, or closure of the eye by patching or other means.

Drug Interactions
Co-administrationofBOTOX® Cosmetic and aminoglycosides1 or other agents interfering withneuromusculartransmission(e.g.,curare-likenondepolarizingblockers,lincosamides, polymyxins,quinidine,magnesiumsulfate,anticholinesterases,succinylcholinechloride)should only be performed with caution as the effect of the toxin may be potentiated.
The effect of administering different botulinum neurotoxin serotypes at the same time or within several months of each other is unknown. Excessive neuromuscular weakness may be exacerbated by administration of another botulinum toxin prior to the resolution of the effects of a previously administered botulinum toxin.
Pregnancy: Pregnancy Category C
Administration of BOTOX® Cosmetic is not recommended during pregnancy. There are no adequate and well-controlled studies of BOTOX® Cosmeticinpregnantwomen.When pregnant mice and rats were injected intramuscularly during the period of organogenesis, the developmentalNOEL(NoObservedEffectLevel)ofBOTOX® Cosmeticwas4Units/kg.Higher doses(8Units/kgor16Units/kg)wereassociatedwithreductionsinfetalbodyweightsand/or delayed ossification.

Higher doses resulted in death of the dams. The rabbit appears to be a very sensitive species to BOTOX® Cosmetic.
If the patient becomes pregnant after the administration of this drug, the patient should be apprised of the potential risks, including abortion or fetal malformations that have been observed in rabbits.
Carcinogenesis, Mutagenesis, Impairment of Fertility

ADVERSE REACTIONS
General
BOTOX® and BOTOX® Cosmetic contain the same active ingredient in the same formulation. Therefore adverse events observed with the use of BOTOX® also have the potential to be associated with the use of BOTOX® Cosmetic.
The most serious adverse events reported after treatment with botulinum toxin include spontaneous reports of death, sometimes associated with anaphylaxis, dysphagia, pneumonia, and/orothersignificantdebility.
There have also been reports of adverse events involving the cardiovascular system, including arrhythmiaandmyocardialinfarction,somewithfataloutcomes.Someofthesepatientshad riskfactorsincludingpre-existingcardiovasculardisease(seeWARNINGS).
Newonsetorrecurrentseizureshavealsobeenreported,typicallyinpatientswhoarepredisposed to experiencing these events. The exact relationship of these events to the botulinum toxin injection has not been established. Additionally, a report of acute angle closure glaucoma one day after receiving an injection of botulinum toxin for blepharospasm was received, with recovery four months later after laser iridotomy and trabeculectomy. Focal facial paralysis, syncope and exacerbation of myasthenia gravis have also been reported after treatment of blepharospasm.
In general, adverse events occur within the first week following injection of BOTOX® Cosmetic and while generally transient may have a duration of several months or longer. Localized pain, infection,inflammation,tenderness,swelling,erythemaand/orbleeding/bruisingmaybe associatedwiththeinjection.Localweaknessoftheinjectedmuscle(s)representstheexpectedpharmacological action of botulinum toxin. However, weakness of adjacent muscles may also occur due to spread of toxin.
Glabellar Lines
In clinical trials of BOTOX® Cosmetic the most frequently reported adverse events following injection of BOTOX® Cosmetic were headache*, respiratory infection*, flu syndrome*, blepharoptosis and nausea.
Lessfrequentlyoccurring(<3%)adversereactionsincludedpainintheface,erythemaatthe injectionsite*,paresthesia*andmuscleweakness.Whilelocalweaknessoftheinjectedmuscle(s) is representative of the expected pharmacological action of botulinum toxin, weakness of adjacent muscles may occur as a result of the spread of toxin. These events are thought to be associated with the injection and occurred within the first week. The events were generally transient but may last several months or longer.

Immunogenicity
Treatment with BOTOX® Cosmetic may result in the formation of neutralizing antibodies that may reduce the effectiveness of subsequent treatments with BOTOX® Cosmetic by inactivating the biological activity of the toxin. The rate of formation of neutralizing antibodies in patients receiving BOTOX® Cosmetic has not been well studied.
The critical factors for neutralizing antibody formation have not been well characterized. The results from some studies suggest that botulinum toxin injections at more frequent intervals or at higher doses may lead to greater incidence of antibody formation. The potential for antibody formation may be minimized by injecting the lowest effective dose given at the longest feasible intervals between injections.
Postmarketing Experience
Transient ptosis, the most frequently reported complication, has been reported in the literature inapproximately5%ofpatients.Therehasbeenasinglereportofdiplopia,whichresolved completely in three weeks.

Injection Technique
Glabellar facial lines arise from the activity of the corrugator and orbicularis oculi muscles. These muscles move the brow medially, and the procerus and depressor supercilii pull the brow inferiorly. Thiscreatesafrownor“furrowedbrow”.Thelocation,size,anduseofthemusclesvarymarkedlyamong individuals. Lines induced by facial expression occur perpendicular to the direction of action of contracting facial muscles. An effective dose for facial lines is determined by gross observation of the patient’sabilitytoactivatethesuperficialmusclesinjected.
In order to reduce the complication of ptosis the following steps should be taken:
Avoid injection near the levator palpebrae superioris, particularly in patients with larger brow •depressor complexes.
