Hi! My daughter had a stomach virus that started on December 25...then we took her to the doctor on December 29 because she was still feeling bad. She ended up also getting diagnosed with strep throat and an ear infection and was prescribed Azithromycin, which she has taken for two days. She is still having diarrhea and vomiting. We took her to urgent care last night due to the vomiting and diarrhea. They said to keep giving her the medicine to get rid of the strep and that it didn t appear that she was allergic to the medication because she was vomiting/having diarrhea hours after the dose. We just tried giving her the third dose, and she vomited again after having about half of the dose (200 mg once per day for five days). She basically vomited while receiving a dose....so we don t know what to do - keep giving her the medicine or not. No one can really explain why she keeps vomiting or having diarrhea, although her bowel movements appear to be improving and are not as runny. Thanks.
