There are eight types of botulinum toxin, named type A–H. Types A and B are capable of causing disease in humans, and are also used commercially and medically. Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals. Type H is considered the deadliest substance in the world – an injection of only 2 ng can cause death to an adult. Botulinum toxin types A and B are used in medicine to treat various muscle spasms and diseases characterized by overactive muscle. Commercial forms are marketed under the brand names Botox and Dysport, among others.
Botox is injected in and around the head on an average of every three months. It blocks signals from nerves and paralyzes the muscles, ultimately preventing migraines. It is known to relax the muscles that usually contract during migraines. It’s also the only FDA-approved medication to prevent migraines before they even start! It’s known to prevent about nine migraines per month.
"In the majority of these cases, it's the doctors at the front line who start using Botox off-label, and then we see the treatment of things we never expected the toxin to work for," says Min Dong, a researcher at Harvard Medical School who studies botulinum toxins in the lab and has no financial ties to Allergan. "I meet with physicians who are using the toxin everywhere--for diseases you would never know about."
The procerus is a small triangular-shaped muscle that intermingles with the inferior aspect of the frontalis muscle. The muscle runs from the aponeurotic fascia on the nasal bones and inserts into the skin of the inferior forehead. The medial portion of the eyebrow and the skin of the lower forehead are drawn down by the procerus muscle, producing transverse wrinkle lines over the bridge of the nose.

Side effects from therapeutic use can be much more varied depending on the location of injection and the dose of toxin injected. In general, side effects from therapeutic use can be more serious than those that arise during cosmetic use. These can arise from paralysis of critical muscle groups and can include arrhythmia, heart attack, and in some cases seizures, respiratory arrest, and death. Additionally, side effects which are common in cosmetic use are also common in therapeutic use, including trouble swallowing, muscle weakness, allergic reactions, and flu-like syndromes.
BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
