What is anakinra?
Anakinra (Kineret) is a synthetic (man-made), injectable, interleukin-1 (IL-1) receptor antagonist that blocks the effects of human interleukin-1. It is used in the treatment of rheumatoid arthritis.
Quick GuideRheumatoid Arthritis (RA) Symptoms & Treatment
Why is anakinra prescribed to patients?
Anakinra is used for treating the signs and symptoms of moderate to severe rheumatoid arthritis in individuals 18 years of age or older. It is not a first-line drug but is used in individuals who have failed at least one of the other disease-modifying drugs that are used to treat rheumatoid arthritis. It can be used alone or in combination with other agents, but it should not be used with drugs that block tumor necrosis factor alpha such as infliximab (Enbrel) and etanercept (Remicade). (See drug interactions.)
Anakinra also is for used for treatment of neonatal-onset multisystem inflammatory disease (NOMID) due to cryopyrin-associated periodic syndromes (CAPS).
What are the side effects of anakinra?
The most common side effects are reactions at the site of injection, for example, redness, swelling and pain.
Other minor side effects include:
The most serious side effects are an increase in infections and a decrease in the number of white blood cells (neutropenia) and platelets.
Anakinra should not be started in individuals with active infections.
Infections occur more frequently when anakinra is used in combination with drugs that block tumor necrosis factor.
What is the dosage for anakinra?
- The dose of anakinra for rheumatoid arthritis is one subcutaneous injection of 100 mg daily. The dose should be administered at approximately the same time every day.
- The dose for treating neonatal-onset multisystem inflammatory disease (NOMID) is 1-2 mg/kg daily up to a maximum dose of 8 mg/kg.
Which drugs or supplements interact with anakinra?
Anakinra should not be combined with drugs that block tumor necrosis factor (TNF) alpha. Combining anakinra with drugs that block tumor necrosis factor such as infliximab (Enbrel) and etanercept (Remicade) or other drugs that reduce function of the immune system increases the risk of serious infections.
Is anakinra safe to use during pregnancy or while breastfeeding?
Anakinra has not been studied in pregnant women.
It is not known if anakinra is excreted in the breast milk of females who are nursing.
What else should I know about anakinra?
What preparations of anakinra are available?
Pre-filled syringes, 100 mg
How should I keep anakinra stored?
Anakinra should be kept refrigerated at 2 C to 8 C (36 F to 46 F)
How does anakinra work?
Anakinra blocks the effects of human interleukin-1, and is used in the treatment of rheumatoid arthritis. IL-1 is a protein that is produced by many cells in the body. It is found in increased amounts within joints that are inflamed by arthritis. IL-1 attaches to receptors on the tissues within and surrounding the joints as well as on the cells that are responsible for inflammation, for example, white blood cells. The attachment of IL-1 activates the cells to release enzymes that promote inflammation. The enzymes destroy the cartilage and bone and contribute to pain and swelling of the joints. Anakinra attaches to the IL-1 receptor and prevents IL-1 from attaching to the receptor. Thus, the inflammatory and enzyme-releasing effects of IL-1 are prevented and pain and swelling of the joints are reduced.
When was anakinra approved by the FDA?
Anakinra was approved by the Food and Drug Administration in November 2001.

Biological TherapyThe purpose of biological therapy is to boost the immune system to fight infection and disease. Types of biological therapy include monoclonal antibodies, interleukin-2 (IL-2), and colony-stimulating factors. Side effects of biological therapy may include flu-like symptoms, nausea, vomiting, and diarrhea.
Biologics Biologic Drug Class
A biologic drug is a product that is produced from living organisms or contain components of living organisms. Biologics include recombinant proteins, tissues, genes, allergens, cells, blood components, blood, and vaccines. Biologics are used to treat numerous disease and conditions, for example:
- Chronic migraine
- Hepatitis B
- Hemophilia Respiratory syncytial virus (RSV) prophylaxis
- HPV prevention
- Rheumatoid arthritis
- Inflammatory bowel disease
Side effects of biologics depend upon the specific biologic drug; however, common side effects may include:
- High blood glucose levels
Drug interactions, preparations, and pregnancy and breastfeeding information should be reviewed prior to administering these drugs.
Drug InteractionsDrug interactions occur frequently. Get facts about the types of drug interactions, what substances or other things that may interact with drugs such as OTC drug and prescription drugs, vitamins, food(s) (grapefruit), and laboratory tests. Find out how to protect yourself from potential drug interactions.
Juvenile ArthritisJuvenile idiopathic arthritis (juvenile rheumatoid arthritis or JRA) annually affects one child in every thousand. There are six types of JIA. Treatment of juvenile arthritis depends upon the type the child has and should focus on treating the symptoms that manifest.
Rheumatoid ArthritisRheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease.

Still's DiseaseStill's disease (systemic-onset juvenile rheumatoid arthritis) is a disorder characterized by inflammation with high fever spikes, fatigue, salmon-colored rash, and/or arthritis. Though there have been several theories regarding the cause(s) of Still's disease, the cause is not yet known. Many symptoms of Still's disease are often treatable with anti-inflammatory drugs.
