Neurological Side Effects of Lisinopril

Lisinopril is an angiotensin-converting enzyme inhibitor, or ACE inhibitor, commonly prescribed to treat high blood pressure. Physicians also prescribe it for congestive heart failure and migraine headaches. Lisinopril is the generic version of the drug, while brand names include Prinivil and Zestril.

Dizziness

• The primary neurological side effect of Lisinopril is dizziness, particularly when people first begin taking the drug. This dizziness usually results from blood pressure dipping too low.

Age Considerations

• Elderly people tend to be more sensitive to lisinopril, particularly to the dizziness side effect.

Prevention/Solution

• People taking lisinopril should drink plenty of water and other non-caffeinated fluids, because dehydration can lower blood pressure. Drinking alcohol can worsen the dizziness effect.

Other Neurological Effects

• Other neurological side effects of lisinopril can include headache and lightheadedness. People who experience fainting or extreme dizziness while taking lisinopril may have very low blood pressure and should consult a physician.

Additional Side Effects

• Lisinopril also can cause temporary side effects of fatigue, drowsiness, insomnia, nausea, diarrhea, coughing or blurred vision. If these effects are prolonged or become worse, people should tell their doctor.
