Off Label Uses
Familial Mediterranean fever
Evidence from a small number of patients in a short-term controlled trial and noncontrolled trials suggests that anakinra may reduce the frequency of attacks in patients with familial Mediterranean fever (FMF) who are resistant or intolerant to colchicine [Ben-Zvi 2017], [Kucuksahin 2016], [Pecher 2017].
Based on European League Against Rheumatism (EULAR) guidelines for the management of FMF, interleukin-1 (IL-1) blockers are recommended for patients unresponsive or resistant to the maximum dose of colchicine [EULAR [Ozen 2016]].
Gout, treatment of acute flares (when conventional therapy is ineffective, contraindicated, or not tolerated)
Data from a case series and several retrospective chart reviews have suggested anakinra may be beneficial for the treatment of acute flare of gout in patients who are refractory to, intolerant of, or have contraindications to conventional therapy (eg, colchicine, NSAIDs, corticosteroids) [Ghosh 2013], [Ottaviani 2013], [So 2007]. Additional data may be necessary to further define the role of anakinra in this condition.
Based on European League Against Rheumatism (EULAR) evidence-based recommendations for the management of gout, interleukin-1 (IL-1) blockers (eg, anakinra) may be considered for treating acute gout flares in patients with frequent flares and who have contraindications to other anti-gout therapies including colchicine, NSAIDS, and corticosteroids. Following flare treatment with interleukin-1 (IL-1) blockers, urate-lowering therapy should be adjusted to meet uricemia target levels.
Evidence from small controlled and noncontrolled trials and several case reports/series indicates that anakinra may be effective in preventing recurrences in patients with recurrent pericarditis refractory to conventional therapy.
European Society of Cardiology (ESC) guidelines on the diagnosis and management of pericardial diseases recommend that intravenous immunoglobulin, anakinra, or azathioprine be considered in cases of infection-negative, corticosteroid-dependent recurrent pericarditis in patients not responsive to colchicine.
Hypersensitivity to E. coli-derived proteins, anakinra, or any component of the formulation
Neonatal-onset multisystem inflammatory disease (NOMID): SubQ: Initial: 1 to 2 mg/kg daily in 1 to 2 divided doses; adjust dose in 0.5 to 1 mg/kg increments as needed; usual maintenance dose: 3 to 4 mg/kg daily (maximum: 8 mg/kg daily). Note: Once-daily administration is preferred; however, the dose may also be divided and administered twice daily.
Familial Mediterranean fever (off-label use): SubQ: 100 mg once daily (Ben-Zvi 2017)
Gout, treatment of acute flares (when conventional therapy is ineffective, contraindicated, or not tolerated) (off-label use): SubQ: 100 mg once daily (Ghosh 2013; Ottaviani 2013; So 2007). Most patients received therapy for 3 days (So 2007). Additional data may be necessary to further define the role of anakinra in this condition.
Pericarditis (recurrent) (off-label use): SubQ: 100 mg once daily. Dosing based on limited data with treatment periods up to 6 months (Brucato 2016; Cantarini 2010). Additional data is necessary to further define the role of anakinra in the treatment of this condition.
Rheumatoid arthritis (RA): SubQ: 100 mg once daily (administer at approximately the same time each day).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Refer to adult dosing.
Familial Mediterranean Fever; colchicine-resistant: Very limited data available: Children ≥2 years and Adolescents: SubQ: 2 mg/kg/dose once daily; dose, frequency, and duration of therapy were adjusted as needed based on clinical response, usual reported duration: 4 to 8 months; some patients may require a longer duration. Patients continued to receive concomitant colchicine (Eroglu 2015).
Juvenile idiopathic arthritis (JIA): Limited data available:
Systemic-onset JIA (SOJIA): Children and Adolescents: SubQ: Initial: 1 to 2 mg/kg/dose once daily; maximum initial dose: 100 mg; if no response, may titrate typically at 2-week intervals by doubling dose up to 4 mg/kg/dose once daily; maximum dose: 200 mg (Dewitt 2012; Gattorno 2006; Hedrich 2012; Irigoyen 2006; Lequerré 2008; Nigrovi 2011; Quartier 2011).
Polyarticular course JIA: Children ≥2 years and Adolescents: SubQ: 1 mg/kg once daily; maximum dose: 100 mg (Ilowite 2009; Reiff 2005).
Kawasaki disease, refractory to IVIG: Very limited data available; reported dosing highly variable: Infants >2 months and young children (eg, <4 years): SubQ: 1 to 6 mg/kg/day in 1 to 2 divided doses; dosing based on case reports and expert recommendation as an alternate therapeutic option; a case report in a 2-year old reported a dose of 1 mg/kg/dose once daily; another case report in a 3-year old reported a dose of 2 mg/kg/dose once daily for 14 days; a higher dosing regimen was described in an 11-week old who had therapy initiated at 3 mg/kg/dose twice daily and further increased to 3 mg/kg/dose three times daily due to continued worsening clinical presentation; after clinical improvement and corticosteroid taper begun the anakinra dose was decreased to 4 mg/kg/dose twice daily (AHA [McCrindle 2017]; Cohen 2012; Sanchez-Manubens 2017; Shafferman 2014).
Multisystem inflammatory syndrome in children (MIS-C) associated with SARS-CoV-2: Very limited data available, optimal regimen and place in therapy not well established:
Note: Use is based on limited experience in patients with MIS-C, extrapolation from other disease states, expert opinion, and case reports in adults (AAP 2020; ACR [Henderson 2020]; Aronoff 2020; Elias 2020; Hennon 2020). As data and experience continue to rapidly evolve, dosing will be updated as appropriate.
Infants, Children, and Adolescents: IV, SubQ: 2 to 10 mg/kg/day in divided doses every 6 to 12 hours; doses up to 13 mg/kg/day have been described (AAP 2020; ACR [Henderson 2020]; Chiotos 2020; Lee 2020); duration dependent upon clinical course, tapering over 3 weeks has been suggested (AAP 2020). Note: While poorly documented, the IV route has been suggested in MIS-C recommendations, particularly in patients requiring high doses or who have bleeding concerns, subcutaneous skin conditions, or neurologic comorbidities (Mehta 2020). Dosing and use of IV route is extrapolated from other disease states (eg, macrophage activation syndrome, Kawasaki disease, secondary hemophagocytic lymphohistiocytosis), limited published experience (pediatric and adult), and expert opinion (AAP 2020; ACR [Henderson 2020]; Cavalli 2020; Dimopopoulos 2020; Eloseily 2020; Halyabar 2019; Mehta 2020; Pontali 2020).
Neonatal-onset multisystem inflammatory disease (NOMID) or chronic infantile neurological, cutaneous, and articular syndrome (CINCA) [cryopyrin-associated periodic syndromes (CAPS)]: Infants, Children, and Adolescents: SubQ: Initial: 1 to 2 mg/kg/day in 1 to 2 divided doses; adjust dose in 0.5 to 1 mg/kg increments as needed to control inflammation; usual maintenance dose: 3 to 4 mg/kg/day; maximum daily dose: 8 mg/kg/day. Note: Once-daily administration is preferred; however, the dose may also be divided and administered twice daily.
Rheumatoid arthritis: Adolescents ≥18 years: SubQ: 100 mg once daily; administer at approximately the same time each day.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
SubQ: Allow solution to warm to room temperature prior to use (30 minutes). Inject into outer area of upper arms, abdomen (do not use within 2 inches of belly button), front of middle thighs, or upper outer buttocks. Rotate injection sites; do not administer into tender, swollen, bruised, red, or hard skin or skin with scars or stretch marks.
Store in refrigerator at 2°C to 8°C (36°F to 46°F); do not freeze. Do not shake. Protect from light. Discard any unused portion.

<1%, postmarketing, and/or case reports: Hepatitis (noninfectious), hypersensitivity reaction (including anaphylaxis, angioedema, pruritus, skin rash, urticaria), increased serum transaminases, metastases (malignant lymphoma, malignant melanoma), opportunistic infection, thrombocytopenia (including severe)
Concerns related to adverse effects:
• Anaphylaxis/hypersensitivity reactions: Hypersensitivity reactions, including anaphylactic reactions and angioedema, have been reported; discontinue use if severe hypersensitivity occurs; medications for the treatment of hypersensitivity reactions should be available for immediate use.
• Infections: Associated with an increased risk of serious infections in rheumatoid arthritis studies. Anakinra should not be initiated in patients with an active infection. If a patient receiving anakinra for rheumatoid arthritis develops a serious infection, therapy should be discontinued; if a patient receiving anakinra for neonatal-onset multisystem inflammatory disease (NOMID) develops a serious infection, the risk of a NOMID flare should be weighed against the risks associated with continued treatment. Safety and efficacy have not been evaluated in immunosuppressed patients or patients with chronic infections; the impact on active or chronic infections has not been determined. Immunosuppressive therapy (including anakinra) may lead to reactivation of latent tuberculosis or other atypical or opportunistic infections; test patients for latent TB prior to initiation, and treat latent TB infection prior to use.
• Injection site reactions: Injection site reactions commonly occur (within first 4 weeks of therapy) and are generally mild with a duration of 14 to 28 days.
• Malignancy: May affect defenses against malignancies; impact on the development and course of malignancies is not fully defined. As compared to the general population, an increased risk of lymphoma has been noted in clinical trials; however, rheumatoid arthritis has been previously associated with an increased rate of lymphoma.
• Neutropenia: A decrease in neutrophil count may occur during treatment. Assess neutrophil count at baseline, monthly for 3 months, then every 3 months for up to 1 year. In a limited number of patients with NOMID, neutropenia resolved over time with continued anakinra administration.
• Asthma: Use with caution in patients with asthma; may have increased risk of serious infection.
• Renal impairment: Use caution in patients with renal impairment; extended dosing intervals (every other day) are recommended for severe renal insufficiency (CrCl <30 mL/minute) and ESRD.
• Elderly: Use caution due to the potential higher risk for infections.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling.
• Immunizations: Patients should be brought up to date with all immunizations before initiating therapy; live vaccines should not be given concurrently. There is no data available concerning the effects of therapy on vaccination or secondary transmission of live vaccines in patients receiving therapy.
CBC with differential (baseline, then monthly for 3 months, then every 3 months for a period up to 1 year); TB test (baseline); serum creatinine; signs/symptoms of infection
Based on limited information, use of anakinra may be continued through conception in women with rheumatic and musculoskeletal diseases who are planning a pregnancy and not able to use alternative therapies; use should be discontinued once pregnancy is confirmed. Conception should be planned during a period of quiescent/low disease activity (ACR [Sammaritano 2020]).
Based on limited information, use of anakinra may be continued in males with rheumatic and musculoskeletal diseases who are planning to father a child (ACR [Sammaritano 2020]).
Information related to the use of anakinra during pregnancy is limited (Berger 2009; Chang 2014; Duman 2019; İlgen 2017; Ozdogan 2019; Smith 2018; Youngstein 2017).
Until additional information is available, anakinra is not currently recommended for the treatment of rheumatic and musculoskeletal diseases during pregnancy. Anakinra should be discontinued once pregnancy is confirmed (ACR [Sammaritano 2020]).
Women exposed to anakinra during pregnancy may contact the Organization of Teratology Information Services (OTIS), Rheumatoid Arthritis and Pregnancy Study at 1-877-311-8972.
