Use this medication exactly as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Rilonacept is given as an injection under the skin of your stomach, thigh, or upper arm. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.

Rilonacept is usually given to adults in two injections at a time, each on a different place on your body. The two injections are then given once per week.

Children may be given one or two injections at a time once per week. Follow your doctor's instructions.

Do not use this medication more often than once per week unless your doctor has told you to.

You will need to mix rilonacept with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication. After mixing rilonacept with a diluent, you must use it within 3 hours.

Each vial (bottle) of rilonacept is for a single use only. Throw the vial away after one use, even if there is still medication left in it.

Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

To be sure this medication is not causing harmful effects, your blood may need to be tested on a regular basis. Do not miss any follow-up visits to your doctor for blood or urine tests.

Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), loss of appetite, nausea and vomiting, mouth sores, or unusual weakness.

Store the unmixed powder medicine in the refrigerator and protected from light. Do not freeze. Keep each vial in the original container until you are ready to mix your medicine.
