I have taken Myrbetric for ten weeks. It did nothing for my incontinence for 9 weeks then one night I stayed dry all night to my surprise. I have stayed dry ever since. I have had no side effects unless it could be hair loss. I had a difficult total hip replacement at the end of August and I attributed the hair loss to anesthesia. I spent ten days in the hospital post surgery. Now I read it could have been the Myrbetric. It is probably worth having thinner hair to not be incontinent to me. I found getting 90 days of pills by mail order pharmacy saved me $ 80 compared to the local pharmacy.
