Hello, Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem. Morning cough,irritation of throat is very common in patients with acid reflux as during night the throat gets irritated and person starts to cough when gets up in morning. It needs life style modification before any medication , here is what one needs to do. 1) Avoid coffee, caffeine, Fizzy drinks , junk food, smoking, alcohol (What ever is relevant). 2) Take small multiple meals instead of few larger ones. 3) Drink much fluids. 4) Use fruits and vegetables more than meat. 5) Use fiber diet like fruits vegetables whole grain bread and fiber supplements if needed. 6) Stay physically active. 7) If he is over weight reduce it. 8) After trying out all these measure you can use syrup Gaviscon thrice a day this will keep a check at stomach acid. 9) You can discuss with you doctor about prokinetics like motillium ,itopride these are very effective in controlling reflux which will eventually control throat issues. Mentioning in the end because of it s importance: DO NOT sleep immediately after dinner eat 2 hours before sleeping, don t eat large or fatty meal don t take caffeine fizzy drinks specially in night , walk for 15-30 minutes after dinner. Allergy can be a cause because as drippy nose you mentioned but allergy alone wont be causing it , in my opinuon reflux has been playing it s part in this problem. For allergy he can simply take tablet Citerizine 10mg daily at night and see if it helps, but along with that one has to control reflux in this case. I hope this answered your question, If you have more queries I am happy to answer you. Regards. Dr.Muhammad Ahmad
