Hi doctor,

I have a bit of a cough for several days already, but I do not have yellowish phlegm; instead, clear one. The smoke of a cigarette always triggers my cough or if someone near me is smoking. Also, I think my cough is caused by too much heat in terms of weather which brings specks of dust or when cooking something (especially when someone is sautéing). I took a tablet Cetirizine to stop my coughing, but it is still present, especially at night. Can you please tell me what I shall do to stop my coughing and feel better? Thank you.



Welcome to

I want to know few more details so that I can help you with your problem.

  1. How long has this been going on? I assume it has been there for quite some time because you can identify the triggers of your cough. You also mentioned that your cough occurs at night.
  2. Do you sneeze a lot when exposed to dust?
  3. Do you have asthma?

The coughing that you have seems to be a sign of a hyperreactive airway (beginning asthma). The best way to control this is to avoid the triggers. I suggest you with tablet Zykast (Montelukast 10 mg and Levocetirizine 5 mg) one tablet after dinner for one to two weeks and see if it improves. If it persists, the next step would be to start an anti-asthma inhaler Seretide 125 Evohaler (Salmeterol 25 mcg and Fluticasone propionate 125 mcg) two puffs twice daily.

I hope this helps.
