Drug Interaction Report

Using ropeginterferon alfa-2b together with SORAfenib can increase the risk of side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. You may be more likely to develop anemia, bleeding problems, or infections. Contact your doctor if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, or pain and burning during urination. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

You may experience reduced absorption of SORAfenib in the presence of food. Take SORAfenib on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. This will make it easier for your body to absorb the medication.
