Hi Dr I have been on Venlor xr 75 2/day for past 2years. currently 50 years old. Blood test show not in menopause however am experiencing night sweats and very heavy periods extending for 3 weeks at a time. Dark, clotting and weight. Pap smears all clear. what is the chance that ongoing use of venlor may be the cause of this heavy extended bleeding? Weight gained 16kgs in past year and fasts result in no weight loss. Many thanks Debbie
