My 4 year son is suffering from viral fever last 3 days. He is almost recovered as now fever is not going high. We are giving meftagesic - P whenever he is body temp is increasing. And his body temp remains normal for 4-5 hrs. After that again we have to give him meftagesic - P. But he is coughing a lot and vomits while eating anything. So whenver we try to give antibiotic droxyl he immediately he starts coughing and then vomits. He is also getting whooping /wheezing sound while coughing. Please suggest on priority. Since last 2 days we were giving homeopathy medicine now started aloepathy medicine. We are giving levoline syrup for cough. How this levolin syrup is for viral cough.
