What is incobotulinumtoxinA?
IncobotulinumtoxinA, 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.
IncobotulinumtoxinA is used to treat cervical dystonia (severe spasms in the neck muscles). IncobotulinumtoxinA is also used to treat muscle spasms (stiffness) in the arms.
IncobotulinumtoxinA 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.
IncobotulinumtoxinA may also be used for purposes not listed in this medication guide.
You should not receive this medicine 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.
The botulinum toxin contained in this medication can spread to other body areas beyond where it was injected. This can cause serious life-threatening side effects.
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 an injection.
Before taking this medicine

IncobotulinumtoxinA is made from human plasma (part of the blood) which may contain viruses and other infectious agents.

It may take up to 7 days after injection before neck muscle spasm symptoms begin to improve.
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.
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.
