Before taking this medicine

Taking Xeljanz XR can increase your risk of life-threatening medical problems including serious infections, a hole or tear in your digestive tract, a heart attack or stroke, blood clots, or cancer. Tell your doctor if you've had:

  • a weak immune system or chronic infection (such as tuberculosis, shingles, HIV, or hepatitis);

  • any type of cancer;

  • kidney disease, a kidney transplant, or if you are on dialysis;

  • diverticulitis, an ulcer in your stomach or intestines;

  • heart problems;

  • a heart attack, stroke, or blood clot;

  • high cholesterol; or

  • if you've ever smoked.

Tell your doctor if you've been sick with signs of infection, such as fever, chills, muscle aches, cough, trouble breathing, skin sores, diarrhea, or painful urination.

Tell your doctor if you've had or been exposed to tuberculosis, or if you recently traveled. Some infections are more common in certain parts of the world, and you may have been exposed during travel.

Also tell your doctor if you have ever had:

  • liver disease (especially hepatitis B or C);

  • chronic lung disease;

  • diabetes; or

  • if you are scheduled to receive any vaccine.

Using Xeljanz XR may increase your risk of developing certain cancers, such as lymphoma or lung cancer. Ask your doctor about this risk.

Tell your doctor if you are pregnant or plan to become pregnant. Having rheumatoid arthritis or ulcerative colitis during pregnancy may increase the risk of premature birth or low birth weight. The benefit of treating these conditions with Xeljanz XR may outweigh any risks to the baby.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of tofacitinib on the baby.

If you are a woman, Xeljanz XR may affect your ability to have children during treatment and in the future.

Do not breastfeed while you are using Xeljanz XR, and for at least 18 hours after your last dose (36 hours if you take extended-release tablets). If you use a breast pump during this time, do not feed the milk to your baby.

Do not give this medicine to a child without medical advice. The extended-release tablets are not approved for use by anyone younger than 18 years old.

How should I take Xeljanz XR?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

You may take Xeljanz XR with or without food.

Swallow the extended-release tablet whole and do not crush, chew, or break it.

Measure liquid medicine with the supplied measuring device (not a kitchen spoon).

Doses are based on weight in children and teenagers. Your child's dose may change if the child gains or loses weight.

A safe dose of tofacitinib is not the same for all conditions. Avoid medication errors by using only the form and strength your doctor prescribes.

You may get infections more easily, even serious or fatal infections. You will need frequent medical tests.

If you've ever had shingles (herpes zoster) or hepatitis B or C, using Xeljanz XR can cause these viruses to become active or get worse.

Part of a tablet shell may appear in your stool but this will not make the medicine less effective.

Store this medicine in the original container at room temperature, away from moisture, heat, and light. Throw away any unused liquid after 60 days.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking Xeljanz XR?

Avoid receiving a "live" vaccine. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).
