What is onabotulinumtoxinA (Botox) (Botox, Botox Cosmetic)?
OnabotulinumtoxinA (Botox), also called botulinum toxin type A, is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.
Botox is used to treat cervical dystonia (severe spasms in the neck muscles), muscle spasms in the arms and hands, and severe underarm sweating (hyperhidrosis).
Botox is also used to treat certain eye muscle conditions caused by nerve disorders. This includes uncontrolled blinking or spasm of the eyelids, and a condition in which the eyes do not point in the same direction.
Botox is also used to prevent chronic migraine headaches in adults who have migraines for more than 15 days per month, each lasting 4 hours or longer. Botox should not be used to treat a common tension headache.
Botox Cosmetic is used to temporarily lessen the appearance of facial wrinkles.
Botox may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about Botox (Botox, Botox Cosmetic)?
The botulinum toxin contained in this medication can spread to other body areas beyond where it was injected. This has caused serious life-threatening side effects in some people receiving botulism toxin injections, even for cosmetic purposes.
Call your doctor at once if you have a hoarse voice, drooping eyelids, vision problems, severe muscle weakness, loss of bladder control, or trouble breathing, talking, or swallowing. Some of these effects can occur up to several weeks after a botulinum toxin injection.
Botulinum toxin injections should be given only by a trained medical professional, even when used for cosmetic purposes.
Do not seek botulinum toxin injections from more than one medical professional at a time. If you switch healthcare providers, be sure to tell your new provider how long it has been since your last botulinum toxin injection.
Using this medication more often than prescribed will not make it more effective and may result in serious side effects.
You should not receive this medication if you are allergic to botulinum toxin, or if you have an infection, swelling, or muscle weakness in the area where the medicine will be injected.
Before receiving a botulinum toxin injection, tell your doctor if you have ALS ( Lou Gehrig's disease), myasthenia gravis, Lambert-Eaton syndrome, a breathing disorder, trouble swallowing, facial muscle weakness, a change in the appearance of your face, seizures, bleeding problems, heart disease, if you have had or will have surgery, or if you have ever received other botulinum toxin injections such as Dysport or Myobloc.
The effects of a botulinum toxin injection are temporary. Your symptoms may return completely within 3 months after an injection. After repeat injections, it may take less and less time before your symptoms return, especially if your body develops antibodies to the botulinum toxin.
