Strong CYP3A4 Inhibitors : See the Full Prescribing Information for dosage modification for patients with atopic dermatitis, ulcerative colitis, and Crohn’s disease.
Strong CYP3A4 Inhibitors Upadacitinib exposure is increased when it is co-administered with a strong CYP3A4 inhibitor (such as ketoconazole, clarithromycin, and grapefruit), which may increase the risk of adverse reactions [see Clinical Pharmacology ( 12.3 )] .
Monitor patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondylarthritis, pJIA, or giant cell arteritis closely for adverse reactions when co-administering RINVOQ/RINVOQ LQ with strong CYP3A4 inhibitors.
