Does Botox work for hyperhidrosis?
Botox—often associated with cosmetic wrinkle reduction—is also a particularly effective treatment for underarm hyperhidrosis. Botox injections use botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat.
In auxiliary hyperhidrosis, Botox helps to stop or greatly reduce the symptoms. This will usually happen within two weeks of treatment and the effects may last between four and six months. If you find that this treatment has helped you, it can be repeated to give you the greatest benefit.
Normally, your nervous system activates your sweat glands when your body temperature rises. This is how your body automatically cools itself. In people with hyperhidrosis, however, the nerves that signal the sweat glands are overactive.
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. Botox prevents sweating in the specific area where it’s injected.
