How does this medication work? What will it do for me?

Botulinum toxin is a neuromuscular paralytic agent. It blocks the nerves that are responsible for muscle activity and helps to relax muscles that are in constant contraction (spasm). In adults, it is used to treat conditions that are caused by certain muscles going into spasm. These include:

• blepharospasm, a condition where the eyelid will not stay open because of a spasm of a muscle in the eye
• cervical dystonia, also known as spasmodic torticollis, a condition in which the muscles of the neck stay in a state of contraction
• focal spasticity such as arm, ankle or foot spasms after a stroke
• chronic drooling (sialorrhea) caused by nerve disorders
• In children of 2 years of age or older and who weigh 12 kg or more, it may be used to treat chronic drooling (sialorrhea) caused by nerve disorders.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

How should I use this medication?

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.
