Hello. ACE inhibitor group of drugs (including lisinopril) are known to cause this kind of irritating cough that goes on for weeks to months. It is because they induce hyper-reactivity of airways. The airways therefore start reacting to many triggers. These are not allergies! Even after stopping ACE inhibitors, the cough may continue for 2-3 weeks. The best treatment is to take inhaled corticosteroids for 2-3 weeks, cough suppressants (if there is no wheeze) and most importantly, be away from the triggers of cough such as cold/ spicy/oily food, deodorants, face powder, smoke etc. Last 6 medicines in your list are all supplementary food. If you exercise daily and take good food, you may not need them. -Dr. Tushar
