Zepatier is taken as one tablet once a day, whereas Viekira Pak requires taking four tablets daily and must be taken with food. Common Zepatier side effects include fatigue and headache, while Viekira Pak can cause nausea, itching, and rash. Additionally, Viekira Pak contains ritonavir, which can interact with many other medications. Both medications require testing for hepatitis B before starting treatment due to the risk of reactivation.
