Botox for Sweating - How Long Do the Effects Last?
In my practice I have successfully used Botox to treat individuals with excess sweating. Botox works by blocking the nerve chemical that tells sweat glands to turn on, so instead of relaxing a muscle like it does for wrinkles, it quiets the glands themselves in the area treated, whether that's the underarms, palms, or soles. Most patients notice a real drop in sweating within a few days to a week, and that reduction stays local to the treated area.
There is some variability in the length of relief patients can get but most of my patients have seen 6 months to 1 year. As the effect wears off, sweating gradually returns to baseline rather than stopping suddenly, so you'll have a good sense of when it's time to schedule another treatment. If you notice no improvement at all after treatment, that's worth discussing at a follow up visit.
Clinical Context
Botox for sweating targets a different pathway than Botox for wrinkles. Instead of relaxing muscles, it blocks the nerve chemical (acetylcholine) that signals sweat glands to activate. It's injected in a grid pattern across the underarms, palms, or soles rather than at a few muscle points. Because it works locally in the treated area, it won't reduce sweating happening elsewhere on the body from unrelated triggers.
