Hi my son is 3 years 10 months old. I have been giving him levolin syrup of 5 mL after food whenever he catches cough. This has been prescribed by his doctor before 1 year. But my son’s teacher made me confused that levolin is not cough syrup and cough syrup should be given before food. Can any expert kindly help me to clear this confusion? Is levolin not used for treating cough? And when to consume? Thank you 🙏
