Lisinopril can cause nausea, headaches, anxiety, insomnia, drowsiness, nasal congestion and sexual dysfunction.
Lisinopril should be stopped if there are symptoms
or signs of an allergic reaction including feelings of swelling of the face, lips, tongue or throat. Severe allergic reactions (anaphylaxis) and hives occasionally occur. Rarely, lisinopril may cause a drop in red blood cells, white blood cells, and platelets.
