I was diagnosed with PCOS when I was a bit younger and prescribed metformin, aldactone and birth control pill. I never was good about taking the medicine because I didn't see any other symptom except irregular periods. I wasn't worried about that then but now I am seeing more of the symptoms like weight gain/unability to lose weight/hirutism and hair loss on the scalp. I am so scared it I don't take care of this soon I will be totally bald. Ok, so I have begun a low carb diet and I have the meds I never took. I have aldactone and metformin both 100 mg. They do not expire until sometime in 2012. I don't have insurance now and I don't have access to any endocrinologists or physicians so I was wondering what would the adverse reactions be of me taking the aldactone and metformin now. Any suggestions would be appreciated. Thanks so much!!
