Viekira XR (generic name: dasabuvir, ombitasvir, paritaprevir and ritonavir) is a once-daily, extended-release tablet to treat chronic hepatitis C virus (HCV) genotype 1 infection.

Viekira XR is a fixed-dose combination that contains the same active ingredients as Viekira Pak, but in one single tablet.

Viekira XR, consists of 200 mg of dasabuvir, 8.33 mg of ombitasvir, 50 mg of paritaprevir, and 33.33 mg of ritonavir per tablet.

Viekira Pak is co-packaged with dasabuvir instead of having it all in one tablet.
