Q. I cough every night, which gets better after taking Cetirizine. What should I do?

You are probably having what we call as an allergic pharyngitis, avoid spicy oily and junk food altogether for a few days. Yes dust can be one reason why your nose/throat might be creating a lot of phelgm, sometimes even dust at home(as in when u vaccum or mop the floor or look into old stuff having dust ) can lead to such issues. Besides, even the slightest of acidity can be one hidden cause. In allergic pharyngitis you won't have many tel a tale signs except of mucus irritating your throat. Advice 1.Have simple food with least spices 2.Avoid dust at all costs, wear an n95 mask, cuz that's the only thing effective against dust 3. Consider salt water gargles (one glass of boiled warm water with 2 tsps of salt, dissolve and gargle 4. Keep sipping on warm water 5. Long term use of levocetrizine is not recommended 6. Start an antireflux treatment with tab pantaprazole 40 MG once a day in the morning 25mins before bfast.
