Important warnings This medicine can cause some serious health issues

Intravenous route (solution)

Meningococcal infections, which may rapidly become life-threatening or fatal if not recognized and treated early, have been reported in patients treated with eculizumab.

Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients with complement deficiencies.

Immunize patients with a meningococcal vaccine at least 2 weeks prior to administering the first dose of eculizumab, unless the risks of delaying eculizumab therapy outweigh the risk of developing a meningococcal infection.

Vaccination reduces, but does not eliminate, the risk of meningococcal infections.

Monitor patients for early signs of meningococcal infections and evaluate immediately if infection is suspected.

Eculizumab is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS).

Under the eculizumab REMS prescribers must enroll in the program.

Enrollment in the eculizumab REMS program and additional information are available by telephone: 1-888-SOLIRIS (1-888-765-4747) or at solirisrems.com.
