What is Zilretta?
Zilretta is a steroid that prevents the release of substances in the body that cause inflammation.

Zilretta is not suitable for use in small joints, such as the hand.
Zilretta may also be used for purposes not listed in this medication guide.
You may not be able to receive Zilretta if you have a fungal infection, or a condition called idiopathic thrombocytopenic purpura (ITP).
Before taking this medicine
You should not be treated with this medicine if you are allergic to Zilretta.
Tell your doctor if you have ever had:
an active or chronic infection, including tuberculosis;
idiopathic thrombocytopenic purpura (ITP);
cataracts, glaucoma, or herpes infection of the eyes;

a nerve-muscle disorder, such as myasthenia gravis;

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.
It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.
How is Zilretta given?
Zilretta is given through a needle and can be injected into different areas of the body: into a muscle; into the space around a joint or tendon, or into a lesion on the skin. A healthcare provider will give you this injection.
Not every brand of Zilretta is used for the same conditions or injected into the same body areas. Some brands are given only one time as needed. Others may be given at regular intervals. Carefully follow your doctor's dosing instructions.
Zilretta can weaken (suppress) your immune system, and you may get an infection more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, weakness, cold or flu symptoms, skin sores, diarrhea, frequent or recurring illness).
Long-term use of steroids can cause harmful effects on the eyes. If you receive Zilretta for longer than 6 weeks, your doctor may want you to have regular eye exams.
Your doctor may instruct you to limit your salt intake while you are receiving Zilretta. You may also need to take potassium supplements. Follow all instructions.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Zilretta.
You should not stop using Zilretta suddenly after long-term repeated use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for a scheduled Zilretta.
When Zilretta is used as a single dose, you will not be on a regular dosing schedule.
What happens if I overdose?
Since Zilretta is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
Using too much Zilretta is not likely to cause serious problems. However, long term use of high doses can lead to thinning skin, easy bruising, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.
What should I avoid while receiving Zilretta?
After injection of triamcinolone into a joint, avoid overusing that joint through strenuous activity or high-impact sports. You could cause damage to the joint.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles. These conditions can be serious or even fatal in people who are using Zilretta.
Do not receive a "live" vaccine or a toxoid vaccine while using Zilretta, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).

What other drugs will affect Zilretta?
Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
Tell your doctor about all your current medicines. Many drugs can affect Zilretta, especially:
an antibiotic or antifungal medication;
birth control pills or hormone replacement therapy;
a diuretic or "water pill";
insulin or oral diabetes medicine;
medicine to treat tuberculosis;
This list is not complete and many other drugs may affect Zilretta. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
