Unresolved Neisseria meningitidis infections. Individuals not vaccinated against Neisseria meningitidis, unless the risks of delaying ravulizumab therapy outweigh the risks of developing a meningococcal infection.

Boxed Warning:

Serious meningococcal infections.


Increased risk of serious meningococcal infections (septicemia and/or meningitis). Vaccinate or revaccinate for meningococcal disease according to ACIP guidelines. Immunize patients without a history of meningococcal vaccination at least 2 weeks prior to treatment. Give 2 weeks of antibacterial prophylaxis if ravulizumab must be initiated immediately and vaccines administered <2 weeks before starting therapy. Monitor closely for signs of meningococcal infection; evaluate immediately if infection is suspected. Discontinue ravulizumab if undergoing treatment for meningococcal infection. Risk of other infections (eg, due to N. species [including gonococcal infections], S. pneumoniae, H. influenza); monitor closely for signs of worsening infection. PNH: risk of hemolysis and other reactions (eg, thrombosis) after treatment discontinuation; monitor closely for at least 16 weeks; if hemolysis signs/symptoms occur, consider restarting ravulizumab. aHUS: risk of TMA complications after treatment discontinuation; monitor for at least 12 months; if TMA occurs, consider reinitiating ravulizumab or organ-specific supportive measures. Pregnancy. Nursing mothers: not recommended (during and for 8 months after last dose).

Pharmacologic Class:

Complement inhibitor.


Administration of PE/PI (plasmapheresis or plasma exchange, or fresh frozen plasma) may reduce ravulizumab serum levels.

Adverse Reactions:

Upper RTI, headache, diarrhea, nausea, vomiting, headache, hypertension, pyrexia; meningococcal infection (may be fatal), infusion reactions (interrupt infusion if cardiovascular instability or respiratory compromise occur).
