Hi, I am Dr Suresh K Yadav MD (paediatrics), I had gone through your question and understand your concerns, Oral rehydration solution and zinc are recommended for diarrhoea , usually it takes 3-7 days to resolve , most important is to take care of hydration by using oral rehydration solution and frequent feeding. Other medicines are not recommended without prescription of a doctor. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions Take care.
