What is the most important information I should know about ZILBRYSQ?
ZILBRYSQ is a medicine that affects part of your immune system. ZILBRYSQ may lower the ability of your immune system to fight certain infections.
  • ZILBRYSQ increases your chance of getting serious and life-threatening meningococcal infections. Meningococcal infections may become life-threatening or fatal if not recognized and treated early.
    • You must complete or update two types of meningococcal vaccines (for both serogroup B infections and serogroup A, C, W, and Y infections) at least 2 weeks before your first dose of ZILBRYSQ if you have not already had these vaccines.
    • If your healthcare provider decided that urgent treatment with ZILBRYSQ is needed, you should receive meningococcal vaccination(s) as soon as possible.
    • If you have not completed or updated vaccinations for meningococcal infections at least 2 weeks before your first ZILBRYSQ dose and ZILBRYSQ therapy must be started right away, you must also receive antibiotics.
    • If you had a meningococcal vaccine in the past, you might need additional vaccination before starting ZILBRYSQ. Your healthcare provider will decide if you need additional meningococcal vaccination.
    • Meningococcal vaccines do not prevent all meningococcal infections. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a meningococcal infection:
  • headache with nausea or vomiting
  • headache and fever
  • headache with a stiff neck or stiff back
  • fever
  • fever and a rash
  • confusion
  • muscle aches with flu-like symptoms
  • eyes sensitive to light
Your healthcare provider will give you a Patient Safety Card about the risk of meningococcal infection. Carry it with you at all times during treatment and for 2 months after your last ZILBRYSQ dose. Your risk of meningococcal infection may continue for several weeks after your last dose of ZILBRYSQ. It is important to show this card to any healthcare provider who treats you. This will help them diagnose and treat you quickly.
ZILBRYSQ is only available through a program called the ZILBRYSQ REMS. Before you can receive ZILBRYSQ, your healthcare provider must:
  • enroll in the ZILBRYSQ REMS.
  • counsel you about the risk of meningococcal infection.
  • give you the Patient Guide, including information about the signs and symptoms of meningococcal infection.
  • give you a Patient Safety Card about your risk of meningococcal infection, as discussed above.
  • make sure that you are vaccinated with two types of meningococcal vaccines and, if needed, get revaccinated with the meningococcal vaccines. Ask your healthcare provider if you are not sure if you need to be revaccinated.
ZILBRYSQ may also increase the risk of other types of serious infections.
  • ZILBRYSQ may increase your chance of getting Streptococcus pneumoniae and Haemophilus influenzae type b. Your healthcare provider will tell you if you should receive the Streptococcus pneumoniae and Haemophilus influenzae type b vaccinations.
  • Certain people may have an increased risk of gonorrhea infection. Talk to your healthcare provider about whether you are at risk for gonorrhea infection, about gonorrhea prevention, and about regular testing.
Call your healthcare provider right away if you have new signs or symptoms of infection.
