My 4 year old daughter was put on Advair about 3 months ago and within the last 3 weeks has been experiencing an unbelievable increase in her need to urinate. We have had her to the pediatrician 4 times in that window as well as urgent care and to a pediatric urologist. She underwent a renal ultrasound and was put on Ditropan. There is no underlying infection, the Ditropan hasn't helped her urge to go potty at all - in fact she had some severe reactions to it - and no one can give me any answers. In the meantime, this she is feeling the need to pee every five minutes AROUND THE CLOCK and simply can't go. No one in our house is sleeping because of it, her head hurts and she has this general feeling of being sick. In fact, her overall behavior and attitude has changed markedly in the last few months - tantrums, easily frustrated, moody. None of the Docs we've seen has linked these symptoms to Advair. We didn't give her the evening dose tonight, so we'll see if it makes a difference in her sleep. Anyone else with kiddos experiencing similar effects?
