What is Rinvoq and How Does It Work?
Rinvoq (upadacitinib) is an oral Janus kinase (JAK) inhibitor, not a biologic, that reduces immune system activity within cells to decrease inflammation. It blocks specific JAK enzymes, primarily JAK1, interrupting signaling pathways involved in autoimmune disease inflammation. This action helps alleviate symptoms like pain and stiffness.
Rinvoq is approved for several moderate to severe inflammatory conditions, often when other treatments like TNF blockers haven't been effective. These include Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA), Atopic Dermatitis (Eczema), Ulcerative Colitis (UC), Crohn's Disease, Ankylosing Spondylitis (AS), Non-radiographic axial spondyloarthritis (nr-axSpA), Giant Cell Arteritis (GCA), and Polyarticular Juvenile Idiopathic Arthritis (pJIA).
The Black Box Warning: Why Rinvoq is High-Risk
The FDA has issued a black box warning for Rinvoq and other JAK inhibitors due to serious or life-threatening risks. This warning stems from a large safety study on another JAK inhibitor. Key risks in the black box warning include serious infections, mortality, malignancies, major adverse cardiovascular events (MACE), and thrombosis (blood clots). TB testing is usually done before treatment.

Other Serious and Common Side Effects
Besides the black box warnings, Rinvoq has other significant side effects. These include gastrointestinal perforations, laboratory abnormalities, and hypersensitivity reactions. Common side effects include upper respiratory infections, nausea, and acne. Healthcare providers should monitor patients for these risks.
Rinvoq vs. Other Medications: A Comparison
Comparing Rinvoq to treatments like the TNF blocker Humira helps contextualize its risks.
| Feature | Rinvoq (upadacitinib) | Humira (adalimumab) |
|---|---|---|
| Drug Class | Janus Kinase (JAK) Inhibitor | Tumor Necrosis Factor (TNF) Blocker |
| Administration | Oral tablet, once daily | Subcutaneous injection, every other week |
| Black Box Warning | Yes, for serious infections, mortality, malignancy, MACE, and thrombosis | Yes, for serious infections and malignancy |
| Key Side Effect Differences | Higher rates of herpes zoster (shingles) and increased blood creatine phosphokinase (CPK). | Injection-site reactions are common. |
| Cardiovascular Risk | Increased risk of MACE specifically highlighted in the black box warning. | Disease interactions include Congestive Heart Failure (CHF). MACE rates were found to be comparable to Rinvoq in one study. |
| Thrombosis Risk | Increased risk specifically highlighted in the black box warning. | No specific thrombosis warning, but can cause hematologic abnormalities. VTE rates were comparable to Rinvoq in one study. |
Conclusion: Balancing Benefit and Risk
Based on its black box warning and potential for serious adverse effects, is Rinvoq a high risk medication? Yes, it is considered a high-risk drug. The decision to use Rinvoq requires a thorough discussion between the patient and healthcare provider to weigh its benefits for managing severe autoimmune diseases against its significant risks. For patients who haven't responded to other treatments, Rinvoq can improve symptoms and quality of life. This necessitates close monitoring for infections, cardiovascular events, cancers, and other complications. Patients must be aware of serious adverse event symptoms and seek prompt medical attention if they occur.
