Hi doctor, my 20-month-old son is having cold and fever on and off for the last 2 months. Before this, he only had a fever and cold when he was 12 months old that got well in 2 days with the paracetamol. He had almost 3 fevers in the last 2 months. For the last fever and cold 2 weeks ago, he had Erythromycin Ethylsuccinate, ibuprofen, and some cough syrup. He has been having runny nose continuously for the last 2 months. I have tried Prospan for his cough last month. Again, yesterday, he started having cough, fever, and vomiting. I gave him some paracetamol and he slept well, got up normally and had his dinner and played well, but again yesterday night got fever. Is anything serious??? What is he having???? Is azithromycin helpful??
