Hello there,

Cough medicines are being prescribed to be taken only for ONE WEEK and your kid has been taking cough medicines for almost 10 days without development to his or her health. You should stop giving him/her those medicines and immediately consult the doctor regarding your kid's cough. The cough might have complications and continuously giving her medicines without doctor's prescription is not healthy. I would advice that you take him or her to the doctor or pediatrician.
