<human>: My son is 3.4 years old and weight is 13 Kg. He is having cough from past 10 days along with fever and cold. Fever is down and he is having light cold. We had given ventryl 4.5 ml dose 3 times per days for 3 days. Still the cough is not reduced. Could you please prescribe best medicine for cough?
<bot>: Hello, Thank you for asking at Chat Doctor. I went through your sons history and would like to make suggestions for you as follows:1. It is possible that after a viral infection, cough persists for a few weeks. If fever has subsided, please do not worry about cough.2. For symptom relief of cough, I would suggest him a cough syrup containing antihistamine like pheniramine.3. Warm saline gargles would also help him to recover early. Hope above suggestions will be helpful to your son. If you have any further query, please feel free to ask at Chat Doctor. Wish your son the best of the health ahead. Thank you & Regards.
