Some people experience frequent or constant excessive sweating (hyperhidrosis) of their hands, feet or underarms, which can seriously interfere with work, recreation or social activities.
There are a number of treatments for hyperhidrosis, but each has limits and drawbacks. A new option for treatment is topical glycopyrronium tosylate (Qbrexza). This is an individually packaged towelette — much like the moist towelettes for hand cleaning — that's soaked in the drug. The product was recently approved to be applied to the armpit for excessive sweating.
Qbrexza is an anticholinergic drug, which is a class of drug that's sometimes taken orally for excessive sweating.
