My 4 year old had tubes placed in both ears and adenoids removed about 2 weeks ago, he was prescribed antibiotic (zithromax) and ear drops antibiotic to both ears, a week ago they did a culture it turns out that he has a yeast infection she prescribed Clotrimazole Topical solution and it says for external use only, I just want to make sure is safe to put this in his ears. I got the drops today I called the doctors office they never called me back, they closed early for the holiday weekend.
