Indication and Important Risk Information

What is ZILRETTA?

ZILRETTA® (triamcinolone acetonide extended-release injectable suspension) is an extended-release corticosteroid approved to manage osteoarthritis knee pain. The benefits and risks of repeat injections have not been demonstrated.

Who should not receive ZILRETTA?

You should not receive a ZILRETTA injection if you are allergic to corticosteroids, triamcinolone acetonide, or any other component of the product.

What possible side effects of corticosteroids could occur with ZILRETTA?

  • Rare serious allergic reactions
  • Effects in the injected knee such as infection (with pain, swelling and restricted motion) or joint damage
  • Increased chance of getting an infection, and a decreased ability to fight an infection
  • Effects on hormone production. These effects can be reversible
  • Elevated blood pressure, sodium and water retention, and potassium loss
  • Intestinal perforation if you have certain gastrointestinal disorders
  • Weakening of bones
  • Changes in behavior or mood disturbances
  • Increased pressure inside the eye

What are the most common side effects of receiving a ZILRETTA injection?

In multiple clinical trials, the most common side effects seen in people taking ZILRETTA were joint pain, headache, joint swelling, back pain, sore throat and runny nose, upper respiratory tract infection, and bruising.

What should you tell your doctor BEFORE receiving a ZILRETTA injection?

Tell your doctor about all of the medications you are taking (including both prescription and over-the-counter medicines) and about any medical conditions, especially if you have high blood pressure, heart disease, ulcers, diverticulitis or other gastrointestinal disorders, kidney problems, diabetes, glaucoma, behavior or mood disorders, and/or infections.

What should you tell your doctor AFTER receiving a ZILRETTA injection?

Contact your doctor if you develop a fever or other signs of infection, have an increase in pain along with swelling of the injected knee, restriction of joint motion, or a general feeling of discomfort. Contact your doctor immediately if you are exposed to chicken pox or measles, or for any new or worsening changes in behavior or mood.

These are not all of the possible side effects with ZILRETTA or corticosteroid medications. Please see the full Prescribing Information at www.ZILRETTALabel.com/PI.pdf. Always contact your doctor if you have questions or experience any side effects.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
