ANC <500 cells/mm3: Discontinue.
Low platelet counts:
Platelets 50,000-100,000 cells/mm3: Interrupt therapy; when platelet count is >100,000 cells/mm3, resume IV tocilizumab at 4 mg/kg (may increase to 8 mg/kg as clinically appropriate) or resume SubQ tocilizumab at every other week dosing (increase frequency to every week as clinically appropriate).
Platelets <50,000 cells/mm3: Discontinue.
IV: Prior to administration, dilute to 50 mL (children <30 kg) or 100 mL (children ≥30 kg and adults) by slowly adding to 0.9% sodium chloride. Use vials for IV to prepare infusion solutions; do not use prefilled SubQ syringes to prepare IV solutions. Withdraw equal volume of 0.9% sodium chloride to the volume of tocilizumab required for dose; slowly add tocilizumab dose into infusion bag or bottle. Gently invert to mix (avoid foaming). Diluted solutions may be stored under refrigeration or at room temperature for up to 24 hours (protected from light) and are compatible with polypropylene, polyethylene (PE), polyvinyl chloride (PVC), and glass infusion containers. Allow diluted solution to reach room temperature prior to infusion.
IV: Allow diluted solution for infusion to reach room temperature prior to administration; infuse over 60 minutes using a dedicated IV line. Do not infuse other agents through same IV line. Do not administer IV push or IV bolus. Do not use if opaque particles or discoloration is visible.
SubQ: Rheumatoid arthritis: When transitioning from IV administration to SubQ administration, give the first SubQ dose instead of the next scheduled IV dose. Administer the full amount in the prefilled syringe. Allow to reach room temperature prior to use. Do not use if particulate matter or discoloration is visible; solution should be clear and colorless to pale yellow. Rotate injection sites; avoid injecting into moles, scars, or tender, bruised, red, or hard skin. Prefilled syringe is available for use by patients (self-administration).
Store intact vials/syringes at 2°C to 8°C (36°F to 46°F). Do not freeze. Protect vials and syringes from light (store in the original package until time of use); keep syringes dry. Solutions diluted for IV infusion may be stored at 2°C to 8°C (36°F to 46°F) or room temperature for up to 24 hours and should be protected from light. Discard unused product remaining in the vials.

Concerns related to adverse effects:
• Anaphylaxis/hypersensitivity reactions: May cause hypersensitivity or anaphylaxis; anaphylactic events including fatalities have been reported with IV administration; hypersensitivity reactions have occurred in patients who were premedicated, in patients with and without a prior history of hypersensitivity, and as early as the first infusion. Medications for the treatment of hypersensitivity reactions should be available for immediate use. Patients should seek medical attention if symptoms of hypersensitivity reaction occur with subcutaneous use. Stop immediately and permanently discontinue treatment in patients who develop a hypersensitivity reaction to tocilizumab. In clinical studies, reactions requiring treatment discontinuation included generalized erythema, rash, and urticaria.
• Elevated liver enzymes: Monitor transaminases. Treatment should be discontinued in patients who develop elevated ALT or AST >5 x ULN. Patients receiving concomitant hepatotoxic drugs (eg, methotrexate) are at an increased risk of developing elevated transaminases; elevations are typically reversible and do not result in clinically evident hepatic injury.
• Fatal infections: [U.S. Boxed Warning]: Serious and potentially fatal infections (including active tuberculosis, invasive fungal, bacterial, viral, protozoal, and other opportunistic infections) have been reported in patients receiving tocilizumab; infection may lead to hospitalization or death. Most of the serious infections have occurred in patients on concomitant immunosuppressive therapy. Patients should be closely monitored for signs and symptoms of infection during and after treatment. If serious infection occurs during treatment, withhold tocilizumab until infection is controlled. Prior to treatment initiation, carefully consider risk versus benefit in patients with chronic or recurrent infections, tuberculosis exposure, history of or current opportunistic infection, underlying conditions predisposing to infection, or patients residing in or with travel to areas of endemic tuberculosis or endemic mycosis. The most common serious infections occurring have included pneumonia, UTI, cellulitis, herpes zoster, gastroenteritis, diverticulitis, sepsis, and bacterial arthritis. Do not administer tocilizumab to a patient with an active infection, including localized infection. Interrupt treatment for serious infection, opportunistic infection or sepsis.
• Gastrointestinal perforation: Use with caution in patients at increased risk for gastrointestinal perforation; perforation has been reported, typically secondary to diverticulitis. Monitor for new-onset abdominal symptoms; promptly evaluate if new symptoms occur.
• Hematologic effects: Neutropenia and thrombocytopenia may occur; may require treatment interruption, dose or interval modification, or discontinuation. Monitor neutrophils and platelets. Do not initiate treatment in patients with an ANC <2,000/mm3 or platelet count <100,000/mm3; discontinue treatment for ANC <500/mm3 or platelet count <50,000/mm3.
• Herpes zoster reactivation: Herpes zoster reactivation has been reported.
• Hyperlipidemia: Therapy is associated with increases in total cholesterol, triglycerides, LDL , and/or HDL; monitor ~4-8 weeks after initiation, then approximately every 6 months. Hyperlipidemia should be managed according to current guidelines.
• Malignancy: Use of tocilizumab may affect defenses against malignancies; impact on the development and course of malignancies is not fully defined, however, malignancies were observed in clinical trials.
• Tuberculosis: [U.S. Boxed Warning]: Tuberculosis (pulmonary or extrapulmonary) has been reported in patients receiving tocilizumab; both reactivation of latent infection and new infections have been reported. Patients should be tested for latent tuberculosis infection before and during therapy; consider treatment of latent tuberculosis used prior to tocilizumab treatment. Some patients who test negative prior to therapy may develop active infection; monitor for signs and symptoms of tuberculosis during and after treatment in all patients. Patients should be evaluated for tuberculosis risk factors with a tuberculin skin test prior to starting therapy. Consider antituberculosis treatment in patients with a history of latent or active tuberculosis if adequate treatment course cannot be confirmed, and for patients with risk factors for tuberculosis despite a negative test.
• Demyelinating CNS disease: Use with caution in patients with pre-existing or recent onset CNS demyelinating disorders; rare cases of CNS demyelinating disorders (eg, multiple sclerosis) have occurred. All patients should be monitored for signs and symptoms of demyelinating disorders.
• Hepatic impairment: Use is not recommended in patients with active hepatic disease or hepatic impairment. Monitor ALT and AST. Do not initiate treatment if ALT or AST is >1.5 times ULN.
Concurrent drug therapy issues:
• Biological DMARDs: Concomitant use with other biological DMARDs (eg, TNF blockers, IL-1 receptor blockers, anti-CD20 monoclonal antibodies, selective costimulation modulators) has not been studied and should be avoided due to the increased risk of infection.
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Elderly: Infection has been reported at a higher incidence in elderly patients compared to younger adults; use with caution in elderly patients.
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.
• Appropriate use: Subcutaneous administration is only indicated for adult patients with rheumatoid arthritis. Do not use subcutaneous injection for IV infusion.
• 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 secondary transmission of infection from live vaccines in patients receiving therapy.
Latent TB screening prior to therapy initiation; neutrophils, platelets, ALT/AST (prior to therapy, 4-8 weeks after start of therapy, and every 3 months thereafter [RA]); neutrophils, platelets, ALT/AST (prior to therapy, at second infusion, and every 2-4 weeks [SJIA, U.S. labeling; SJIA and PJIA, Canadian labeling] or 4-8 weeks [PJIA, U.S. labeling] thereafter); additional liver function tests (eg, bilirubin) as clinically indicated; lipid panel (prior to, at 4-8 weeks following initiation, and every ~6 months during therapy); signs and symptoms of infection (prior to, during, and after therapy); signs and symptoms of CNS demyelinating disorders
Pregnancy Risk Factor
Adverse events have been observed in some animal reproduction studies. Monoclonal antibodies cross the placenta, with the largest amount transferred during the third trimester. A pregnancy registry has been established to monitor outcomes of women exposed to tocilizumab during pregnancy (877-311-8972).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience injection site irritation, rhinorrhea, or rhinitis. Have patient report immediately to prescriber signs of infection, signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; blood in the urine; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any bleeding that is very bad or that will not stop), signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), swelling of hands or feet, severe headache, severe dizziness, passing out, severe abdominal pain, skin growths, burning or numbness feeling, or bowel changes (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
