I have just now become a medicare covered person and had not selected a part d for meds because I have only one RX - estradiol. I got sticker shock at the pharmacy when I refilled it! I have always been interested in natural products for health and take several supplements for various reasons. What might I take to replace the hormone I was taking? I have continued taking it way past menopause because it helps with hot flashes, libido and vaginal dryness, not to mention bone health. I am not really interested in soy products. Thank you fir your time.
