Angiotensin-converting enzyme (ACE) inhibitors are medicines. They treat heart, blood vessel, and kidney problems.
ACE inhibitors are used to treat heart disease. These medicines make your heart work less hard. This keeps some kinds of heart disease from getting worse. Most people who have heart failure take these medicines.
These medicines treat high blood pressure, strokes, or heart attacks. They may help lower your risk for stroke or heart attack.
They also are used to treat diabetes and kidney problems. This can help keep your kidneys from getting worse. If you have these problems, ask your doctor if you should be taking these medicines.
There are many different names and brands of ACE inhibitors. Most work as well as another. Side effects may be different for different ones.
ACE inhibitors are pills that you take by mouth. Take all of your medicines as your doctor told you to. Try to take them at the same time, or times, each day. Do not stop taking your medicines without talking with your doctor first.
Follow up with your doctor regularly. Your doctor will check your blood pressure. Your doctor will also do blood tests to make sure the medicines are working properly. Your doctor may change your dose from time to time.
Plan ahead so that you do not run out of medicine. Make sure you have enough with you when you travel.

Side effects from ACE inhibitors are rare.
You may have a dry cough. This may go away after a while. If it does not, tell your doctor. Sometimes reducing your dose helps. Do not lower your dose without talking with your doctor first.
You may feel dizzy or lightheaded when you start taking these medicines, or if your doctor increases your dose. Standing up slowly from a chair or your bed may help. If you have a fainting spell, call your doctor right away.

If your tongue or lips swell, call your doctor right away, or go to the emergency room. You may be having a serious allergic reaction to the medicine. This is very rare.
