Anticholinergic drugs affect your entire body. Many of their side effects are drying: dry mouth, dry eyes, low blood pressure and dizziness when standing, urinary hesitance, and constipation. These side effects are usually mild and are dependent on the dose given.
- Oxybutinin is the best studied drug for excessive sweating. It works well for sweaty palms, underarms, and faces. About 1/2 of patients treated with oral oxybutinin (5 mg taken by mouth twice daily) get improvement.
- Glycopyrrolate has fewer eye and nervous system side effects when compared with other anticholinergics. In most cases, a combination of non-surgical treatments will handle even the worst case of excessive sweating. Learn more here: https://masterpieceskinrestoration.com/blog/excessive-sweating/
