I started taking this drug on the advise of my urogynecologist after having many years of very frequent bladder infections. I had done everything he had suggested and nothing seemed to stop them. I do not like to take medicine unless it is a last resort, so I reluctantly agreed to try this. His purpose in giving me the drug was to increase the condition of the vaginal tissues to help prevent the infections. I take one gram twice a week. IT WORKS. I have gone almost two years without a bladder infection or bladder spasms I was having. I have a pessery and have it checked and cleaned every 4-5 months and he has reported that the tissues are much more healthy than they have been in the past. I feel very comfortable taking this as I am checked frequently for any signs of problems and it has improved my life. I wish to continue taking this drug.
