Oxybutynin
"This drug is pretty amazing. I've had hyperhydrosis of the palms, soles and underarms since hitting puberty. I was skeptic since I've previously tried botox, iontophoresis and drysol with limited results. However, after three days of taking oxybutynin (5mg 3x a day) I was 95% sweat-free. My only negative things to say about the drug is about side effects. I have gotten fairly dizzy/spaced out a few times, and I experience dry mouth pretty often. However, that's not bad in comparison to the acne I've gotten. I used to get pimples around once a month, however now I have ones lasting for <6 wks, varying in size/colour. I constantly have groups of acne on my face. Does anyone have any remedies? I've tried acne masks, cleansers and tea tree oil."
