When I first went through menopause, my doctor prescribed a traditional HRT patch. It caused break through bleeding and I had mild headaches. So I stopped using them at the recommendation of my doctor. A year later I began seeing a different doctor who prescribed bioidentical HRT or cBHT. My hot flashes disappeared and I began to sleep better. The best news is my osteopenia got better! My dexascan showed great improvement in bone density. I also appreciate that cBHT is plant based. Shame on Pfizer and their product, Premarin. I find the treatment of mares and their foals to make Premarin horrific and disgusting! Please give patients the choice of humane, effective, and beneficial HRT through the use of cBHT.
