First doses of lisinopril can cause dizziness due to a drop in blood pressure.
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.
