Dosing in kidney impairment
Renal Impairment Physicians should consider administration of the prescribed dose of KINERET every other day for patients who have severe renal insufficiency or end stage renal disease (defined as creatinine clearance < 30 mL/min, as estimated from serum creatinine levels) [see Use in Specific Populations and Clinical Pharmacology] .
Dosing in liver impairment
Hepatic Impairment No formal studies have been conducted examining the pharmacokinetics of KINERET administered subcutaneously in patients with hepatic impairment.

Administration Instructions on appropriate use should be given by the healthcare provider to the patient or caregiver. Patients or caregivers should not be allowed to administer KINERET until the patient or caregiver has demonstrated a thorough understanding of procedures and an ability to inject the product correctly. The prescribed dose of KINERET should be administered according to the instructions for use and any unused portions discarded.
After administration of KINERET it is essential to follow the proper procedure for disposal of syringes and any residual drug. Recommend patients to rotate their injection sites to reduce the risk of injection site reactions and injection site amyloid deposits [see Warnings and precautions] . See the “Information for Patients” insert for detailed instructions on the handling and injection of KINERET.
Do not use KINERET beyond the expiration date shown on the carton. Visually inspect the solution for particulate matter and discoloration before administration. There may be trace amounts of small, translucent-to-white amorphous particles of protein in the solution. The prefilled syringe should not be used if the solution is discolored or cloudy, or if foreign particulate matter is present.
If the number of translucent-to-white amorphous particles in a given syringe appears excessive, do not use this syringe.
Drug interactions
Check anakinra against a medication listLabel text (2 paragraphs)
No drug-drug interaction studies in human subjects have been conducted. Toxicologic and toxicokinetic studies in rats did not demonstrate any alterations in the clearance or toxicologic profile of either methotrexate or KINERET when the two agents were administered together. A higher rate of serious infections has been observed in RA patients treated with concurrent KINERET and etanercept therapy than in patients treated with etanercept alone. Use of KINERET in combination with TNF blocking agents is not recommended ( 7 )
7.1 TNF Blocking Agents A higher rate of serious infections has been observed in patients treated with concurrent KINERET and etanercept therapy than in patients treated with etanercept alone [see Warnings and Precautions ( 5.2 )] . Two percent of patients treated concurrently with KINERET and etanercept developed neutropenia (ANC < 1 x 10 9 /L). Use of KINERET in combination with TNF blocking agents is not recommended.
Contraindications
4 CONTRAINDICATIONS KINERET is contraindicated in patients with known hypersensitivity to E coli -derived proteins, KINERET, or any components of the product [see Hypersensitivity Reactions ( 5.3 )] . Known hypersensitivity to E coli -derived proteins, Kineret, or to any component of the product. ( 4 )
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Available data from retrospective studies and case reports on KINERET use in pregnant women are insufficient to identify a drug associated risk of major birth defects, miscarriage, or maternal and fetal adverse events. There are risks to the mother and fetus associated with active rheumatoid arthritis or Cryopyrin-Associated Periodic Syndromes (CAPS). In animal reproduction studies, subcutaneous administration of anakinra to pregnant rats and rabbits during organogenesis demonstrated no evidence of fetal harm at doses up to 25 times the maximum recommended human dose (MRHD).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Published data suggest the risk of adverse pregnancy outcomes in women with rheumatoid arthritis or CAPS is associated with increased disease activity.
Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (<2500 grams), and small for gestational age at birth. Data Human Data The available data from retrospective studies and case reports of anakinra-exposed pregnancies have not identified an increased frequency or pattern of birth defects, miscarriage, or adverse maternal or fetal outcomes. An international multi-center retrospective study of pregnancy outcomes with interleukin-1 inhibitors reported on 23 anakinra-exposed pregnancies. There were 21 live births of healthy infants, 1 miscarriage, and 1 infant with left renal agenesis.
The estimated background rate of detected renal malformations is 0.2-2% of all newborns. Another retrospective study reported on 10 anakinra-exposed pregnancies in women with CAPS. There were 9 live births, 1 miscarriage, and 1 fetal demise in a twin pregnancy. The surviving twin was born healthy. Overall, these data cannot definitively establish or exclude any anakinra-associated risks during pregnancy. Methodological limitations of these data include small sample size and the inability to control for confounders such as the timing of drug exposure, underlying maternal disease, and concomitant medication use. Animal Data Animal reproduction studies were conducted in rats and rabbits.
In embryo-fetal development studies, anakinra was…
