What is Rezdiffra?

Rezdiffra is a prescribed medicine used along with diet and exercise to treat adults with metabolic dysfunction-associated steatohepatitis (MASH) with moderate to advanced liver scarring (fibrosis), but not with cirrhosis of the liver.

This indication is approved based on improvement of MASH and liver scarring (fibrosis). There are ongoing studies to confirm the clinical benefit of Rezdiffra.

Before you take Rezdiffra, tell your healthcare provider about all of your medical conditions, including if you:

• have any liver problems other than MASH.
• have gallbladder problems or have been told you have gallbladder problems, including gallstones
• are pregnant or plan to become pregnant. It is not known if Rezdiffra will harm your unborn baby.
  • A pregnancy safety study for women who take Rezdiffra during pregnancy collects information about the
    health of you and your baby. You or your healthcare provider can report your pregnancy by visiting https://pregnancyregistry.madrigalpharma.com or calling 1-800-905-0324.
• are breastfeeding or plan to breastfeed. It is not known if Rezdiffra passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take Rezdiffra.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

• Rezdiffra and other medicines may affect each other, causing side effects. Rezdiffra may affect the way other medicines work, and other medicines may affect how Rezdiffra works.
• Especially tell your healthcare provider if you take medicines that contain gemfibrozil to help lower your triglycerides because Rezdiffra is not recommended in patients taking these medicines.
• Tell your healthcare provider if you are taking medicines such as clopidogrel to thin your blood or statin medicines to help lower your cholesterol.
