Xeljanz is a strong prescription pill used to treat long-term swelling, pain, and stiffness in the joints and the gut. It belongs to a group of medicines called JAK inhibitors.
Instead of working on the outside of your cells like older treatments, Xeljanz goes straight inside your immune cells to turn off the pain signals:
Blocks the Swelling Switches: Inside your cells, there are tiny chemical switches called JAK enzymes that tell your body to create painful swelling. Xeljanz blocks these switches.
Calms Your Immune System: By turning down these switches, your immune system stops attacking your own body.
Protects Your Body: This stops joint damage, lowers severe pain, and helps clear up swelling in your gut lining.
Rheumatoid Arthritis: Treating severe joint pain and stiffness when standard daily medicines have not worked well enough.
Psoriatic Arthritis: Lowering joint swelling while helping to clear up dry, scaly skin patches.
Ankylosing Spondylitis: Managing long-term swelling and pain that targets your spine and lower back.
Ulcerative Colitis: Calming down severe inflammation, ulcers, and bleeding inside your large intestine (the gut).
Because Xeljanz changes how your blood clots and how your body fights germs, you must never take it if you have:
A History of Blood Clots: Past blood clots in your legs (DVT) or your lungs.
A Severe Active Infection: A current bad infection, like an open infected wound or pneumonia.
Severe Liver Problems: Serious liver damage or active liver diseases.
Pregnancy or Breastfeeding: Xeljanz can harm an unborn baby. Women must use reliable birth control while taking this medicine and for 4 weeks after the last dose. Do not breastfeed while using Xeljanz.
The Twice-A-Day Rule: For the 5mg strength, you will standardly take 1 tablet two times a day (usually 1 in the morning and 1 at night).
With or Without Food: You can swallow the pill with or without food. Taking it with a meal can help prevent a mild upset stomach.
Regular Blood Tests: Your doctor will order blood tests every few weeks to check your blood counts, liver health, and cholesterol levels.
1.Space your pills 12 hours apart:Timing.
Take your pills at the same times every day (for example, 8:00 AM and 8:00 PM) to keep a steady amount of medicine in your body.
2.Swallow the tablet completely whole:Ingestion.
Swallow the tablet whole with a full glass of water. Do not crush, chew, or split the pill.
3.Watch for signs of illness daily:Body Check.
Keep a close watch for any new signs of infection, such as a sudden sore throat, a fever, or painful skin boils.
4.Avoid live vaccines during treatment:Vaccine Safety.
Do not get any "live" vaccines (like the yellow fever vaccine) while using Xeljanz, because your immune system is too weak to handle them safely.
As your body gets used to the medicine, you might notice a few mild changes:
A mild runny nose, blocked sinuses, or a slight sore throat.
Mild nausea, occasional loose stools, or a brief upset stomach.
A slight increase in your cholesterol levels or a temporary drop in your white blood cells (shown on your blood tests).
A mild headache during the first few weeks.
What should I do if I forget to take my daily pill?
If you miss a pill, take it as soon as you remember, as long as your next regular dose is more than 5 hours away. If your next dose is less than 5 hours away, skip the missed pill completely. Take your next pill at your normal time. Never take two pills at once to make up for a missed day.
How long does it take for Xeljanz to work on joint pain?
Many people start to notice less joint swelling and better movement within 2 to 4 weeks. However, it can take 3 to 6 months of taking the pill every single day to get the full benefit and completely calm down the inflammation.
Can I take normal pain relievers like Ibuprofen with Xeljanz?
Yes. You can safely take standard pain relievers (like ibuprofen or paracetamol) alongside Xeljanz if you need extra help during a sudden arthritis flare-up. Always confirm your full list of medicines with your specialist.
