I have been on Premarin since 1992, .625mg for many years, recently down to .3 dosage. I am 63 years old, and had surgical menopause in 1992. I have tried a couple of time to get off Premarin, but with no success. My health is good, regular mammograms, DEXA scans are good. Should I still not be on this? I take about 3 pills a week.
