Drug Interaction Report

Using mycophenolic acid together with ritlecitinib can increase the risk of serious infections as well as some cancers. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. Contact your doctor immediately if you develop signs and symptoms of infection such as fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. 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.

Take mycophenolic acid on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. Food may reduce the absorption of mycophenolic acid. This will make it easier for your body to absorb the medication. Do not crush, chew, or cut the tablets. The tablets have a special coating to protect the stomach from irritation.
