- Mechanism of Action: By blocking specific JAK enzymes, the drug prevents immune system signals that cause joint damage, inflammation, and digestive issues.
- Physical Description: The brand name Xeljanz typically appears as a white, round, film-coated tablet with “Pfizer” on one side and “JKI 5” on the other.
- Usage Notes: Tablets should be swallowed whole with a full glass of water or juice and must not be chewed, split, or crushed.
- Important Considerations: This medication can increase the risk of serious infections (including tuberculosis), blood clots, and certain cancers. It is not recommended for individuals with severe liver problems or a history of severe infections
