US BOXED WARNING:
Serious meningococcal infections:

• This drug is a complement inhibitor and increases the risk of serious infections caused by Neisseria meningitidis.
• Life-threatening and fatal meningococcal infections have been reported in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.
• Meningococcal vaccination (for serogroups A, C, W, Y, and B) should be completed or updated according to current ACIP recommendations at least 2 weeks before administering this drug unless the risk of delaying therapy outweighs the risk of developing a serious infection.
• Monitor for signs of meningococcal infections and evaluate immediately if infection is suspected, as patients receiving this drug are at increased risk for invasive disease caused by Neisseria meningitidis, even if they develop antibodies following vaccination.
• Due to the risk of serious meningococcal infections, this drug is available only through a restricted program under a REMS.

CONTRAINDICATIONS:

• Unresolved serious Neisseria meningitidis infection

Safety and efficacy have not been established in patients younger than 18 years.
