Hi, Thanks for posting query. Lisinopril is a ACE Inhibitors. The side effects are- hypotension, hyperkalemia (lowering body potassium level), persistent cough, skin rashes, angioedema (sudden swelling of lip, mouth), dysguesia or reversible loss or alteration of taste sensation, etc. But don t worry about these, most people tolerate the drug very well. Wish you a speedy recovery Best Wishes, Dr Sourav Ganguly.
