About XELJANZ & XELJANZ XR
When it comes to the treatment of your moderate to severe rheumatoid arthritis, there are a number of options that don’t involve needles, like XELJANZ XR, an Unjection. Not the only pill for RA, XELJANZ XR is a once-daily pill for adults with moderate to severe RA for whom methotrexate did not work well.
XELJANZ/XELJANZ XR is a medication called a Janus kinase (JAK) inhibitor. It is used to treat adults with moderately to severely active rheumatoid arthritis (RA) in whom methotrexate did not work well. Your healthcare provider can help determine if XELJANZ or once-daily XELJANZ XR is right for you.
For more information, see Is XELJANZ For You?
XELJANZ/XELJANZ XR is the first in a new class of treatments for moderate to severe RA called Janus kinase (JAK) inhibitors. JAK inhibitors work deep inside the cell to disrupt cellular activities that occur in signaling pathways, known as the JAK pathways.

In some patients, XELJANZ can begin to work in as early as 2 weeks to help relieve joint pain and swelling. And, in clinical trials, more than half of XELJANZ patients felt an improvement in RA symptoms at 3 months. Everybody is different though, so your results may differ.
Learn more about how XELJANZ performed in Clinical Trial Results.
XELJANZ has been shown to be effective in slowing the progression of joint damage. In a clinical trial at 6 months, XELJANZ reduced joint damage progression better than methotrexate.
In the ORAL Start Study, XELJANZ patients hadn't taken methotrexate prior to the study. However, XELJANZ is only approved for use in patients for whom methotrexate did not work well. At 6 months, XELJANZ patients got worse by 0.2 units of change on the modified Total Sharp Score (mTSS) scale, while patients taking methotrexate worsened by 0.8. mTSS measures joint damage progression in selected joints of the hands and feet. The higher the amount of change in the mTSS, the more joint damage has progressed.
In the ORAL Scan Study, patients who took XELJANZ and methotrexate had less progression of joint damage after 6 months (0.1) than those who took a placebo and methotrexate (0.5). However, the possibility was high enough that the difference between treatments may have been due to chance alone and not due to XELJANZ, so the results were not considered significant.

The active ingredient in XELJANZ/XELJANZ XR is tofacitinib.
Your healthcare provider should do blood tests before you start receiving XELJANZ/XELJANZ XR, and while you take XELJANZ/XELJANZ XR, to check for the following side effects:
- Changes in lymphocyte counts. Lymphocytes are white blood cells that help the body fight off infections.
- Low neutrophil counts. Neutrophils are white blood cells that help the body fight off infections.
- Low red blood cell count. This may mean that you have anemia, which may make you feel weak and tired.
Your healthcare provider should routinely check certain liver tests.
You should not receive XELJANZ/XELJANZ XR if your lymphocyte count, neutrophil count, or red blood cell count is too low or your liver tests are too high. Your healthcare provider may stop your XELJANZ/XELJANZ XR treatment for a period of time if needed because of changes in these blood test results.
Your healthcare provider should do blood tests to check your cholesterol levels 4 to 8 weeks after you start XELJANZ/XELJANZ XR, and as needed after that.
XELJANZ/XELJANZ XR can reduce RA pain, and help stop further joint damage, even without methotrexate.
No. XELJANZ/XELJANZ XR cannot be taken with a biologic treatment. Be sure to tell your healthcare provider about all the medicines you take.

XELJANZ/XELJANZ XR may cause serious side effects, including:
Serious infections. XELJANZ/XELJANZ XR can lower the ability of your immune system to fight infections. Some people can have serious infections while taking XELJANZ/XELJANZ XR, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections.
- Your healthcare provider should test you for TB before starting and during XELJANZ/XELJANZ XR treatment, and monitor you closely for signs and symptoms of TB infection during treatment.
You should not start taking XELJANZ/XELJANZ XR if you have any kind of infection unless your healthcare provider tells you it is okay. You may be at a higher risk of developing shingles (herpes zoster). People taking the higher dose (10 mg twice daily) of XELJANZ have a higher risk of serious infections and shingles.
Before starting XELJANZ/XELJANZ XR, tell your healthcare provider if you:
- think you have an infection or have symptoms of an infection, such as fever, sweating, or chills; cough; blood in phlegm; warm, red, or painful skin or sores on your body; burning when you urinate or urinating more often than normal; muscle aches; shortness of breath; weight loss; diarrhea or stomach pain; or feeling very tired
- are being treated for an infection
- get a lot of infections or have infections that keep coming back
- have diabetes, chronic lung disease, HIV, or a weak immune system. People with these conditions have a higher chance for infections
- have TB, or have been in close contact with someone with TB
- live or have lived in, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may happen or become more severe if you use XELJANZ/XELJANZ XR. Ask your healthcare provider if you do not know if you have lived in an area where these infections are common
- have or have had Hepatitis B or C
After starting XELJANZ/XELJANZ XR, call your healthcare provider right away if you have any symptoms of an infection. XELJANZ/XELJANZ XR can make you more likely to get infections or make worse any infection that you have.
