Can you please ID this pill and tell me what it does thanks ## Hello, March! How are you? This tablet is manufactured by Qualitest Pharmaceuticals and they list it as containing 5mgs of Lisinopril. The FDA classifies this medication as an ACE inhibitor that is most commonly used to treat high blood pressure and certain cardiac conditions. Its typical side effects may possibly include nausea, dizziness, headache, increased urination, stomach pain and hypotension. Is there anything else I can help with?
