Ezetimibe  Ezetimibe is a medication used to treat high blood cholesterol and certain other lipid abnormalities. Generally it is used together with dietary changes and a statin. Alone, it is less preferred than a statin. It is taken by mouth. It is also available in the fixed combinations ezetimibe/simvastatin, ezetimibe/atorvastatin, and ezetimibe/rosuvastatin. Common side effects include upper respiratory tract infections, joint pain, diarrhea, and tiredness. Serious side effects may include anaphylaxis, liver problems, depression, and muscle breakdown. Use in pregnancy and breastfeeding is of unclear safety. Ezetimibe works by decreasing cholesterol absorption in the intestines. Ezetimibe was approved for medical use in the United States in 2002. It is available as a generic medication. A month supply in the United Kingdom costs the NHS about £26.21 . In the United States the wholesale cost of this amount is about US$5.85. In 2017, it was the 151st most commonly prescribed medication in the United States, with more than four million prescriptions. A 2018 review found that ezetimibe used as sole treatment slightly lowered plasma levels of lipoprotein(a), but the effect was not large enough to be important. A 2015 review found that adding ezetimibe to statin treatment of high blood cholesterol had no effect on overall mortality or cardiovascular mortality, although it significantly reduced the risk of MI and stroke. A 2015 trial found that adding ezetimibe to simvastatin had no effect on overall mortality but did lower the risk of heart attack or stroke in people with prior heart attack. Several treatment guidelines recommend adding ezetimibe in select high risk persons in whom LDL goals cannot be achieved by maximally tolerated statin alone. Ezetimibe is indicated in the United States as an add-on to dietary measures to reduce levels of certain lipids in people with:  Ezetimibe improves the non-alcoholic fatty liver disease activity score but the available evidence indicates it does not improve outcomes of hepatic steatosis. The two contraindications to taking ezetimibe are a previous allergic reaction to it, including symptoms of rash, angioedema, and anaphylaxis, and severe liver disease, especially when taken with a statin. Ezetimibe may have significant medication interactions with ciclosporin and with fibrates other than fenofibrate.
