My daughter had that and they prescribed the exact same creme for her...except it worked. If it were me, I would call the doctor. Our pediatrician has like a nurses advice line and you can tell them what's going on and they can call you in another prescription. Besides the prescription creme I've only used Desitin but that's not for a yeast infection...I don't think? Everyones body is different, something that works for one person might not work for the next. I doubt something over-the-counter would work when the prescription didn't. But I would most definitely ask the doctor before using anything else! Good luck!!! :0)
