Angiotensin-converting enzyme (ACE) inhibitors
Uses for ACE inhibitors
Doctors prescribe ACE inhibitors to prevent, treat or improve symptoms in conditions such as:
- High blood pressure
- Coronary artery disease
- Heart failure
- Diabetes
- Certain chronic kidney diseases
- Heart attacks
- Scleroderma
- Migraines
Your doctor may prescribe other medications in addition to an ACE inhibitor, such as a diuretic or calcium channel blocker, as part of your high blood pressure treatment. ACE inhibitors are usually taken once daily, and many people take them in the morning.
Side effects and cautions
Doctors commonly prescribe ACE inhibitors because they don't often cause side effects.
Possible ACE inhibitor side effects include:
- Dry cough
- Increased blood-potassium level (hyperkalemia)
- Fatigue
- Rash
- Dizziness
- Headaches
- Sleep problems
- Rapid heartbeat
In rare cases — but more commonly in blacks and in smokers — ACE inhibitors can cause some areas of your tissues to swell (angioedema). If it occurs in the throat, that swelling can be life-threatening.
Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin, others) and naproxen (Aleve, others) decrease the effectiveness of ACE inhibitors. While taking an occasional dose of these medications shouldn't change the effectiveness of your ACE inhibitor, talk to your doctor if you regularly take NSAIDs.
Because ACE inhibitors can cause birth defects, don't take them if you are pregnant or plan to become pregnant.
