Hi, I had gone through your question and understand your concerns. You should be worried but not too much. He has signs of enterocolitis. I see similar cases amongst children who visit my clinic. In the first meeting, I advise my patients to go on antibiotic therapy for 5 days. I suggest Cefixime 4 mg/kg/dose twice a day after meal for 5 days,vizylac 1/2 capsule daily,Z&D syrup to stop diarrhea.Follow rice diet,avoid milk. For better digestion you can use enzyme s syrup during meal.You can discuss this with your treating Doctor. At the same time I write him tests as stool culture,stool for rotavirus to confirm the diagnosis. I prefer to monitor this patient as this is very important. Since this is a prescription medicine, I would suggest you to meet the local Doctor to confirm the diagnosis.
