Botox for Hyperhidrosis in hands - are there long or short term side effects?

Botox injections for hyperhidrosis in the hands can be effective in reducing excessive sweating. While they are generally safe, like any medical procedure, there can be potential side effects. Most common are a bit of discomfort or small bruises.

The most relevant complication in hand botox is the development of temporary weakness of the hand muscles. However, this usually resolves as the effects of Botox wear off.

When Botox or any other neuromodulator (Xeomin, Daxxify, Jeaveau, Dysport) is injected into the hands for management of hyperhidrosis, those injections are intentionally placed very superficially. The reason for this precise placement is so that the toxin specifically affects the small muscles controlling the eccrine (sweat) glands. The larger muscles controlling the movement of the fingers are much deeper in the tissue and are spared. In addition, the toxin is heavily diluted and the dose per site is very small - for Botox, 1-2 units per site. In summary, the precise placement of the toxin and the tiny dosages really limits any discernible effect on the larger muscles of the hands which determine dexterity. Now, in reality, if a patient walked into my practice with a specific occupation requiring incredibly precise hand movements where the margin of error is minuscule, (like for example, a professional violinist for the Philharmonic) I might hesitate to manage their hyperhidrosis in this manner. But for the overwhelming majority of patients, there is no effect on manual dexterity or hand strength and Botox remains an incredibly safe and effective treatment modality for this embarrassing problem. I hope this answers your question and wish you luck!

Hi there,
Botox is amazing for Hand Hyperhidrosis. Make sure they use enough product usually 100 units per hand if doing fingers as well. Usually patients don't notice a difference unless they are using there fingers for precision work but that generally diminishes in a few weeks.

Best of luck!
