Metformin
"For Mommy of PCOS, I was diagnosed with PCOS at 17 and have been taking birth control to control most of the side effects since then. I switched doctors and my new doctor recently put me on metformin slow release (which helps a lot with the ugly GI side effects) and spironolactone, which is an anti-testosterone type of drug that works with birth control to control acne and hirsutism (excessive hair growth). Spironolactone and birth control have to be taken together, specially for PCOS because they work better and because spironolactone can cause birth defects, if your daughter where to get pregnant in the future. Metformin has worked great for me and I have been noticing my weight going down, after many years not being able to lose weight."
