Precautions

US BOXED WARNINGS:
SERIOUS INFECTIONS:
-Patients treated with this drug are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Therapy should be discontinued if a patient develops a serious infection or sepsis.
-Healthcare providers should perform a test for latent TB; if positive, treatment for TB should be started prior to starting therapy with this drug. All patients should be monitored for active TB during treatment, even if the initial latent TB test is negative.
MALIGNANCY:
-Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor (TNF) blockers, including this drug.
-Cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers. Almost all had received azathioprine or 6-mercaptopurine concomitantly with a TNF-blocker at or prior to diagnosis. Most cases were reported in patients with Crohn's disease or ulcerative colitis, most of whom were adolescent or young adult males.

CONTRAINDICATIONS:
-Hypersensitivity to the active component or any of the ingredients
-Hypersensitivity to other murine proteins
-Doses greater than 5 mg/kg should not be administered to patients with moderate to severe heart failure (New York Heart Association [NYHA] Functional Class III/IV)

Safety and efficacy have not been established in patients younger than 6 years for Crohn's disease or ulcerative colitis. Safety and efficacy have not been established in patients younger than 18 years for all other indications.
