Zepatier is a prescription medication used in the treatment of chronic hepatitis C, a viral infection that affects the liver. It is a combination drug that contains two active ingredients, elbasvir and grazoprevir, which work together to inhibit the replication of the hepatitis C virus (HCV) within the body. Zepatier is specifically designed to target certain genotypes of the virus, making it a targeted therapy option for patients with genotype 1 or 4 chronic hepatitis C. This medication is taken orally in the form of a tablet and is often praised for its high cure rates and the relatively short treatment duration compared to older therapies. However, like all medications, it can have side effects, and its use must be carefully monitored by a healthcare provider.
