Hydrochlorothiazide / triamterene
"I have high blood pressure and edema. The hydrochlorothiazide definitely made me lose water weight- about 6-7 pounds but it really seemed to cut sexual desire and often made me nauseous and gave me diarrhea. I had to stop taking it because of the nausea. The night after the first day I'd stopped taking it, my sexual desire returned but when I got up to urinate, I noticed the veins on my penis were abnormally enlarged. The veins went back to normal after that night. I think I had a reverse reaction when my body tried to adjust to the medicine being out of my system. Probably the water had no escape mechanism without the medication."
