US BOXED WARNING:
- SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIA: This drug increases the risk of serious infections, especially those caused by encapsulated bacteria (e.g., Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae type B). Life-threatening and fatal infections with encapsulated bacteria have occurred with complement inhibitors; such infections may become rapidly life-threatening or fatal if not recognized and treated early. Vaccination for encapsulated bacteria should be completed or updated at least 2 weeks before the first dose of this drug, unless the risks of delaying this drug outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria in patients taking a complement inhibitor; the manufacturer product information should be consulted for further guidance managing risk of serious infections. Patients taking this drug are at increased risk for invasive disease caused by encapsulated bacteria, even if they develop antibodies after vaccination. Patients should be monitored closely for early signs/symptoms of serious infections and evaluated at once if infection is suspected. Due to the risk of serious infections caused by encapsulated bacteria, this drug is available only through a restricted program under a REMS.
CONTRAINDICATIONS:
- Serious hypersensitivity to the active component or any of the ingredients
- Initiation with unresolved serious infection caused by encapsulated bacteria, including S pneumoniae, N meningitidis, or H influenzae type B
Safety and efficacy have not been established in patients younger than 18 years.
Consult WARNINGS section for additional precautions.
