What is Upadacitinib?

Upadacitinib (brand name: Rinvoq®) is a tablet that belongs to a class of medicines called Janus Kinase (JAK) inhibitor. JAK inhibitors work by blocking signals involved in inflammation. Blocking these signals in Rheumatoid Arthritis reduces pain, stiffness, swelling and damage in the joints.

TGA Boxed Warning: 

Upadacitinib should only be used if no suitable treatment alternatives are available in patients:

  • With a history of atherosclerotic cardiovascular disease or other cardiovascular risk factors (such as current or past long-time smokers).
  • With malignancy risk factors (e.g. current malignancy or history of malignancy).
  • Who are 65 years of age and older.

What benefit can you expect from your treatment?

You may notice some relief of joint swelling, pain and stiffness within the first 2 to 4 weeks of treatment, though it can take up to 3 months to improve.

Stopping upadacitinib

If you stop or delay your upadacitinib treatment, your disease may get worse. Keep taking your treatment, unless advised by your rheumatologist to stop or unless serious side effects occur (see Side effects).

If you stop upadacitinib for any reason, you must contact your rheumatologist. Failure to do so may mean that your treatment may no longer be funded.

How will your condition be monitored?

Are there any side effects?

Most common possible side effects:

The most common side effects reported are mild upper respiratory tract infections (common cold, sinus infections), nausea, cough, and fever. Infections may need treatment and upadacitinib may need to be stopped for a while if you develop infection, so it is important to contact your doctor for advice.

Less common or rare possible side effects:

  • Blood clots in the veins of the legs or lungs and arteries are possible in some people taking upadacitinib. This can happen more often in patients with an inflammatory condition. Further risk factors including heart disease will be assessed by your doctor.

  • Upadacitinib may increase the chance of bowel perforation, though this is rare.
  • People with rheumatoid arthritis are at increased risk of lymphoma and some other cancers. Medicines that change your immune system like upadacitinib may increase this risk.
