- For administration by IV infusion only. Not for intradermal, subcutaneous, IM, IV bolus, or intra-arterial administration.
- Reconstitute each vial with 10 mL of sterile water for injection with a syringe equipped with a 21-gauge or smaller needle. Gently swirl by rotating the vial to dissolve the lyophilized powder. Avoid prolonged or vigorous agitation; do not shake. Foaming of the solution on reconstitution is not unusual; allow to stand for 5 min.
- Further dilute the total volume of reconstituted solution to 250 mL with sodium chloride 0.9% injection. The infusion solution concentration should be between 0.4 and 4 mg/mL.
- Administer by IV infusion over a period of no less than 2 h through an infusion set with an in-line, sterile, nonpyrogenic, low–protein-binding filter with a pore size of 1.2 micrometers or less.
- Do not infuse infliximab concomitantly in the same IV line with any other agent.
- Premedication may be administered at the health care provider's discretion. Premedication could include antihistamines, acetaminophen, and/or corticosteroids.
- Slow or suspend infusion for mild to moderate infusion reactions; upon resolution of the reaction, reinitiate at a lower infusion rate and/or administer acetaminophen, antihistamines, and/or corticosteroids. Discontinue infliximab in patients who do not tolerate the infusion after these interventions.
- Discontinue further infliximab treatment in patients who experience severe infusion-related hypersensitivity reactions.
Store vials in refrigerator (36° to 46°F). Discard any unused reconstituted solution or infusion solution.
Drug InteractionsAbatacept, anakinra
Risk of serious infection and neutropenia may be increased. Coadministration of infliximab and abatacept or anakinra is not recommended.Azathioprine and 6-mercaptopurine
Rare, aggressive, and often fatal postmarketing cases of hepatosplenic T-cell lymphoma have been reported in adolescent and young adult patients with Crohn disease treated with infliximab. All of these hepatosplenic T-cell lymphomas with infliximab have occurred in patients on concomitant treatment with azathioprine or 6-mercaptopurine.TNF blockers (eg, adalimumab, certolizumab, etanercept, golimumab)
Risk of serious infection may be increased. Avoid coadministration of infliximab and another TNF blocker.Tocilizumab
Coadministration may increase the risk of serious infection. Avoid coadministration.Vaccines
Do not coadminister live vaccines.

Serious, life-threatening infections leading to hospitalization and death may occur. Infections include active tuberculosis (TB), including disseminated or extrapulmonary disease or reactivation of latent TB. Test patients for latent TB before and during treatment. Start treatment for latent infection before infliximab use. Other infections include invasive fungal infections (eg, histoplasmosis, aspergillosis, pneumocystosis), which may be disseminated rather than localized diseases. Consider empiric antifungal therapy in patients at risk of invasive fungal infections who develop severe systemic illness. In addition, bacterial, viral, and other infections caused by opportunistic pathogens, including Legionella and Listeria , may occur. Discontinue infliximab in patients developing a serious infection or sepsis. Most patients who develop these infections are taking concurrent immunosuppressants, such as corticosteroids or methotrexate.Malignancies
Lymphoma and other malignancies, some fatal, have been reported in children and adolescents treated with TNF blockers, including infliximab. Rare cases of hepatosplenic T-cell lymphoma have been reported in adolescent and young adult patients with Crohn disease or ulcerative colitis treated with infliximab. All the hepatosplenic T-cell lymphomas with infliximab have occurred in patients on concomitant treatment with azathioprine or 6-mercaptopurine.
Closely monitor patients for signs and symptoms of infection during or after infliximab treatment. Monitor long-term carriers of hepatitis B. Test patients for latent TB before and during treatment. If patients with heart failure are treated, closely monitor during treatment and discontinue infliximab if new or worsening symptoms of heart failure occur. Monitor patients with psoriasis for nonmelanoma skin cancers, especially those who have had prolonged phototherapy treatment. Evaluate patients with signs and symptoms of liver dysfunction for evidence of liver injury.
Category B .
Undetermined. Lactating women should not breast-feed while taking infliximab.
Not studied in children younger than 6 y with Crohn disease; safety and efficacy not established in children for other indications.
Use with caution because of higher incidence of infection in elderly patients.
Reactions vary in their time of onset. Urticaria, dyspnea, and hypotension have occurred during or within 2 h of infliximab infusion; however, serum sickness–like reactions have been observed as early as after the second dose and when infliximab was reinstituted following an extended period without infliximab treatment.
May result in autoantibody formation and, rarely, development of a lupus-like syndrome.
Treatment has been associated with adverse outcomes in patients with heart failure; use in patients with heart failure only after other treatment options have been considered. Worsening heart failure and new-onset heart failure have been reported during postmarketing experience.
Leukopenia, neutropenia, pancytopenia, and thrombocytopenia, sometimes fatal, have been reported. Use with caution in patients with ongoing or a history of significant hematologic abnormalities.
Hepatitis B virus reactivation
Has occurred in patients who are long-term carriers of hepatitis B; some cases were fatal.
Severe hepatic reactions, including acute liver failure, jaundice, hepatitis, and cholestasis, have been reported; some cases were fatal or necessitated liver transplant.
Treatment can be associated with development of antibodies to infliximab. The incidence is approximately 10% in patients given a 3-dose induction regimen followed by maintenance dosing.
Rarely, CNS manifestations of systemic vasculitis, seizure, and new-onset or exacerbation of clinical symptoms and/or radiographic evidence of CNS demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barré syndrome, may occur.
Bring children with Crohn disease up to date with all vaccinations prior to starting infliximab therapy. It is recommended that live vaccines not be given concurrently.
Single doses of up to 20 mg/kg have been administered without toxic effects.
