I am 81, and have been taking Premarin for over thirty years (0.45 mg) and I have no intention of stopping. However, my insurance now refuses to pay for it and wants to substitute Estradiol instead. I'm in great health, sexually active, work full time, have never experienced menopause and don't want to start at my age. My gynecologist has no problem with me continuing to take it, and says that at my age going off Premarin could cause lots of complication. While different women have different health indicators, nothing in my medical history makes Premarin a risk, but getting off of it certainly does. Where can I find a Canadian pharmacy that will fill my prescription?
