RINVOQ, with the active ingredient upadacitinib, is a prescription medication designed for the treatment of various autoimmune and inflammatory conditions. It belongs to a class of drugs known as Janus kinase (JAK) inhibitors, which work by blocking the activity of one or more of the Janus kinase family of enzymes, thereby interrupting the signaling pathway that leads to inflammation. RINVOQ is commonly prescribed for conditions such as rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, among others. It is typically administered in the form of an oral tablet. As with any medication, it is important to use RINVOQ under the guidance of a healthcare professional, as it can have potential side effects and may interact with other medications.
