This medication can spread to other parts of the body after your injection, causing serious (possibly fatal) side effects. These can occur hours or even weeks after the injection. However, the chances of such serious side effects occurring when this medication is used for migraines or skin conditions such as wrinkles, eye spasm, or excessive sweating are extremely unlikely.
Children being treated for muscle spasms have the greatest risk of these effects, as well as anyone that has certain medical conditions (see Precautions section). Discuss the risks and benefits of this medication with your doctor.
Seek immediate medical attention if any of these rare but very serious side effects occur: chest pain, difficulty breathing, excessive muscle weakness, irregular heartbeat, severe difficulty swallowing or speaking, loss of bladder control.
USES: 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.
