My 2 year old started coughing 4 weeks back. Ther is no cold or fever not really clear what's triggering his cough but he coughs until he throws up. The only thing that's helping him is montair lc kid syrup and the effect lasts for 24 hours and soon after that the coughing starts again. He's already taking the syrup for more than 2 weeks now. I've taken him to many doctors got his blood test and x rays done all are normal but still the coughing doesn't go. The paediatric pulmonologist who prescribed is recommending to switch to puffs if symptoms don't stop eve after 15 days of montair lc kid. Can someone help me how I can help my kid.
