I have been prescribed Omnicef for cystic acne for 9 months. I continuously suffer from vaginal/anul itching. The medication helps alittle with the acne but the itching and burning makes my life a living hell. I will take the medication for a while and then get so fed up with the itching and frequent trips to the bathroom. I thought something was wrong with me. I would not prescribe this to a young child. i am shocked to see so many parents posting their children's symptoms. I can barely stand it, I can only imagine what a child feels like on this medication. Definetly not the greatest antibiotic out there. My dermatologist said it was mild as vaginal itching was something I said I did not want to experience. Unfortunetly I am stuck with it!
