question: I have a 2.5 year old daughter (12.5 kgs) who is having cough since last 3 weeks. It looks like dry cough. There is no chest congestion but she has runny nose which is sometimes clear and sometimes yellow. Cough is worst when she sleeps. She was on bricanyl for last 3 weeks with no respite. Now she is prescribed Relent syrup 7 ml twice a day for 5 days and nasal spray Nasivion three times a day for 5 days.Does this look ok ? why would she be coughing so badly for last 3 weeks ? Is it allergy or cold infection which would need antibiotics ?
