There are different types of botulinum toxin products (toxin A and B) with different uses (eye problems, muscle spasms, migraines, cosmetic, overactive bladder). Different brands of this medication deliver different amounts of medication. Your doctor will choose the correct product for you.
Botulinum toxin is used to treat certain eye disorders such as crossed eyes(strabismus) and uncontrolled blinking (blepharospasm), to treat muscle spasms or movement disorders (such as cervical dystonia, torticollis), and to reduce the cosmetic appearance of wrinkles. It is also used to prevent headaches in people with very frequent migraines. Botulinum toxin relaxes muscle by blocking the release of a chemical called acetylcholine.
Botulinum toxin is also used to treat overactive bladder by patients who do not respond to or who cannot tolerate the side effects of other medications. It helps to reduce leaking of urine, feeling of needing to urinate right away, and frequent trips to the bathroom.
It is also used to treat severe underarm sweating. Botulinum toxin works by blocking the chemicals that turn on the sweat glands.
Botulinum toxin is not a cure, and your symptoms will gradually return as the medication wears off.

When treating overactive bladder, it is injected into the bladder.
Your dose, the number of injections, the site of injections, and how often you receive the medication will be determined by your condition and your response to therapy. Most people start to see an effect within a few days to 2 weeks, and the effect usually lasts 3 to 6 months.
