I am 18 years old turing 19. Its been 3 years and my period doesnt come without pills. I took birth-control pills so that I can have a normal period but then my Doctor prescribed me to take Glucophage 500 mg twice a day after food but it has side effects like dizziness, nausea, low blood pressure and diarrehea... I went to pharmacies and asked about the medicine ( Glocophage), they say its good but it is not making me feel good. The last pharmacy I went to suggested that I should take Glucophage XR. I still didnt take it, Im still using Glucophage. He said that they're both the same but Im scared. Im sick of taking pills... any suggestions or help? much appreciated.
