Side Effects

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Call 911 or other emergency services right away if you have:

What To Think About

Be active and eat a cholesterol-lowering diet in addition to taking this medicine. Ask your doctor for advice on a diet that can help lower cholesterol.

Taking medicine

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.

Advice for women

Do not use this medicine if you are pregnant or planning to get pregnant. If you need to take this medicine, talk to your doctor about how you can prevent pregnancy.

If you are breastfeeding, talk to your doctor before using ezetimibe. Do not use ezetimibe and a statin if you are breastfeeding.


You will have regular doctor visits and tests to check your cholesterol level and to check for side effects.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
