Botox is a neurotoxin made from the microbes that cause botulism (a kind of food poisoning). But don’t worry, it’s safe if used appropriately by a medical professional.

Botox is most well known as a cosmetic treatment to smooth facial wrinkles by temporarily paralyzing muscles. Doctors also use Botox to treat neuromuscular conditions like migraine, muscle spasms, and hyperhidrosis, a condition characterized by abnormal and excessive sweating.

You may be a candidate for Botox if your sweating fails to improve with prescription antiperspirants. Botox has been FDA-approved for people who sweat excessively from their armpits. It may also be used “off-label” to reduce sweating in other areas, such as the hands, feet, and face.

Note

Off-label refers to using a medication for something other than what it was approved to treat. In this case, it means that Botox hasn’t gone through the same amount of rigorous testing to confirm its effectiveness and safety for treating excessive sweating in other areas of the body.

When you receive Botox injections directly into the area of your body that commonly sweats, your overactive nerves are essentially paralyzed. When your nerves can’t signal your sweat glands, you don’t sweat. However, Botox only prevents sweating in the specific area where it’s injected.

Currently, Botox has only been approved for the treatment of underarm sweating. Studies have found varying results, but there’s ample evidence that Botox can reduce armpit sweat production by more than 50 percent for at least 6 months.

Doctors use it “off-label” to treat other areas of the body.
