Drug Interaction Report

Talk to your doctor before using ribavirin together with mercaptopurine. Combining these medications can increase the risk of side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. This can make you more likely to develop anemia, bleeding problems, or infections. Contact your doctor if you experience potential signs and symptoms of these conditions such as paleness of skin, fatigue, dizziness, fainting, unusual bleeding or bruising, fever, chills, sore throat, body aches, or other flu-like symptoms. 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.

Food can enhance the levels of ribavirin in your body. Ribavirin should be taken with food or just after eating. This will make it easier for your body to absorb the medication. Do not take it on an empty stomach. Swallow the tablet or capsule whole.

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