I have suffered from painful intercourse for years. Went through menopause in my early 40s. I am now 68. Lubricants do not seem to help. My doctor thinks I am a good candidate for osphena. I am hesitant because of the side affects and the price. Is there a generic brand? My plan D will not cover it. I considered trying osphena for 3-6 months wondering if the results (if good) were long lasting.
