Anakinra is used, alone or in combination with other medications, to reduce the pain and swelling associated with rheumatoid arthritis. Anakinra is in a class of medications called interleukin antagonists. It works by blocking the activity of interleukin, a protein in the body that causes joint damage.
Anakinra comes as a solution to inject subcutaneously (under the skin). It is usually injected once a day, at the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use anakinra exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Anakinra comes in prefilled glass syringes. There are 7 syringes in each box, one for each day of the week. Use each syringe only once and inject all the solution in the syringe. Even if there is still some solution left in the syringe after you inject, do not inject again. Dispose of used syringes in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.
Do not shake prefilled syringes. If the solution is foamy, allow the syringe to sit for a few minutes until it clears. Do not use a syringe if its contents look discolored or cloudy or if it has anything floating in it.
You can inject anakinra in the outer thigh or stomach. If someone else is giving you the injection, it can be injected in the back of the arms or buttocks. To reduce the chances of soreness or redness, use a different site for each injection. You do not have to change the part of the body every day, but the new injection should be given about 1 inch (2.5 centimeters) away from the previous injection. Do not inject close to a vein you can see under the skin.
Before you use anakinra for the first time, read the manufacturer's information for the patient that comes with it. Ask your doctor or pharmacist to show you how to inject anakinra.
To administer the injection, follow these steps:

Keep syringes and injection supplies out of the reach of children. Store anakinra syringes in the refrigerator. Do not freeze. Protect from light. Do not use a syringe that has been at room temperature for more than 24 hours.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests before and during treatment to check your body's response to anakinra.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
