### input:
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 ?

Hello. Thank you for asking at Chat Doctor. I went through your daughters' history, its runny nose & cough without chest congestion for last 3 weeks. I guess fever is not a symptom here. Firstly, I would not suspect a serious condition here. I would think of either allergy or post-viral cough (it is common to continue coughing for some weeks, sometimes more than a month, after viral infection). Regarding treatment, I would suggest an antihistamines (such as cetirizine or levocetirizine) and montelukast daily for your daughter. This will take care of both nasal symptoms & cough. As nasal blockade is not a problem with your daughter, I would not suggest using Position for more than 3 days. Rather I would suggest nasal saline spray daily to irrigate nasal cavities. Antibiotics are not required for viral infections or allergies. However, if your daughter develops fever or fast breathing, I would suggest you to consult a pediatrician. Hope this will help you. Wish your daughter a fast recovery and the best of the health. Regards.
