Rarely, an angiotensin-converting enzyme (ACE) inhibitor can make your blood pressure get too low and cause symptoms. This happens in about 1-2 people out of every 100 taking an ACE inhibitor.
This happens most often to those who also:
- take water pills (called diuretics)
- are on a low-salt diet
- take other medicines that affect blood pressure
- are vomiting or have diarrhea
- do not drink enough water
Feeling dizzy or lightheaded may be a sign of low blood pressure. Lie down if you feel faint or dizzy and contact your doctor right away. Your doctor will work with you to make sure your blood pressure stays in a healthy range. Sometimes this means changing your diet, fluid intake, or medicine dosage. For most people, side effects like dizziness go away as they get used to the medicine.
If you don't feel okay, call your doctor right away!
