Can ezetimibe raise liver enzymes or harm the liver?
Yes. Ezetimibe can affect the liver in some people. It may cause increases in liver enzyme blood tests (such as ALT and AST), and rare cases of serious liver injury have been reported. Risk can be higher if you already have liver problems or if ezetimibe is used with a statin (statin + ezetimibe tends to be used when cholesterol needs additional lowering). [1]
What symptoms should you watch for?
If ezetimibe affects the liver, symptoms can include jaundice (yellow skin or eyes), dark urine, right-sided upper belly pain, unusual fatigue, and nausea/vomiting. If you develop these symptoms, you should contact a clinician promptly. [1]
Who is more at risk?
People with pre-existing liver disease are generally at higher risk for liver-related side effects, and combination therapy with a statin can increase the chance of liver enzyme elevations compared with ezetimibe alone. [1]
What do clinicians monitor while taking ezetimibe?
Clinicians typically use periodic blood tests to monitor liver function, especially if you have risk factors, symptoms, or you’re on ezetimibe together with a statin. If liver enzymes rise significantly, the prescriber may adjust therapy or stop the drug. [1]
When should you avoid ezetimibe or get urgent care?
Seek urgent medical advice if you have symptoms suggestive of significant liver injury (for example, yellowing of the skin/eyes or dark urine). If you already have known significant liver disease, your prescriber may weigh risks and benefits carefully and choose monitoring or an alternative plan.
