I started using Premarin cream, I'd have to look at the tube to see the dosage, twice weekly for atrophic vaginitis and urinary burning and frequency. It's helped, I think. But my dr. said to be careful because it can "stop working" if you use too much.Has this ever happened to you? Anyone know about this? Dr. has moved out of town and I am scheduled to see a new one next week.Any help appreciated!!!!
