Warnings
May cause neutropenia, decreased platelets, elevated liver transaminases, and increased lipid parameters; monitor neutrophils, platelets, lipids, and liver function tests every 4-8 weeks
Impact of treatment is unknown regarding development of malignancies, but malignancies were observed in clinical studies; treatment with immunosuppressants may increase risk of malignancies
Anaphylaxis or serious hypersensitivity reactions have occurred, including fatalities, with or without concomitant arthritis therapies
Impact of treatment with tocilizumab on demyelinating disorders is unknown, but multiple sclerosis and chronic inflammatory demyelinating polyneuropathy were reported rarely in RA clinical studies; monitor for signs and symptoms potentially indicative of demyelinating disorders
Caution if increased risk for GI perforation; gastrointestinal perforation reported, primarily as complications of diverticulitis; promptly evaluate patients presenting with new onset abdominal symptoms for early identification of gastrointestinal perforation
Pregnancy and Lactation
Insufficient data available in pregnant women to determine whether there is a drug-associated risk for major birth defects and miscarriage
No data available on the presence of tocilizumab in human milk, effects of the drug on the breastfed infant, or effects of the drug on milk production
Maximum Dosage
May use alone or in combination with methotrexate or other DMARDs
Not recommended in patients with an ANC<1,000/mm3 , platelet count <50,000 mm3, or ALT/AST >10x ULN
IV infusion
4 mg/kg IV q4Weeks initially; may increase to 8 mg/kg q4Weeks based on clinical response
Not to exceed 800 mg/dose q4weeks
SC injection
- Weight <100 kg: 162 mg SC every other week, followed by an increase to weekly based on clinical response
- Weight ≥100 kg: 162 mg SC weekly
Giant Cell Arteritis
Not recommended in patients with an ANC<1,000/mm3 , platelet count <50,000 mm3, or ALT/AST >10x ULN
IV
- 6 mg/kg IV q4Weeks in combination with tapering course of glucocorticoids
- May be used alone following glucocorticoid discontinuation; if necessary, interrupt dosing for management of dose-related laboratory abnormalities (eg, elevated liver enzymes, neutropenia, thrombocytopenia)
- Not to exceed 600 mg/infusion
SC
- 162 mg SC weekly in combination with a tapering course of glucocorticoids
- Based on clinical considerations, may consider 162 mg SC every other week in combination with tapering course of glucocorticoids
- May be used alone following glucocorticoid discontinuation; if necessary, interrupt dosing for management of dose-related laboratory abnormalities (eg, elevated liver enzymes, neutropenia, thrombocytopenia)
Transitioning from IV to SC
- Administer first SC dose instead of next scheduled IV dose
- Dose interruption or reduced administration frequency of SC dose from every week to every other week dosing may be needed for management of dose-related laboratory abnormalities
Systemic Sclerosis-Associated Interstitial Lung Disease
162 mg SC qWeek
Dose interruption may be needed for managing dose-related laboratory abnormalities (eg, elevated liver enzymes, neutropenia, thrombocytopenia)
SC administration with prefilled ACTPen autoinjector not studied in SSc-ILD
IV administration not approved for SSc-ILD

Cytokine Release Syndrome
8 mg/kg IV once; may be administered as alone or in combination with corticosteroids
If no clinical improvement in the signs and symptoms of CRS occurs after initial dose, may administer up to 3 additional doses; allow 8-hr interval between consecutive doses
