What is the most important information I should know about EMPAVELI?
EMPAVELI is a medicine that affects your immune system. EMPAVELI may lower the ability of your immune system to fight infections.
  • EMPAVELI increases your chance of getting serious infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. These serious infections may quickly become life-threatening or cause death if not recognized and treated early.
    • You must complete or be up to date with the vaccines against Streptococcus pneumoniae and Neisseria meningitidis at least 2 weeks before your first dose of EMPAVELI.
    • If you have not completed your vaccines and EMPAVELI must be started right away, you should receive the required vaccines as soon as possible.
    • If you have not been vaccinated and EMPAVELI must be started right away, you should also receive antibiotics to take for as long as your healthcare provider tells you.
    • If you have been vaccinated against these bacteria in the past, you might need additional vaccines before starting EMPAVELI. Your healthcare provider will decide if you need additional vaccines.
    • Vaccines do not prevent all infections caused by encapsulated bacteria. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a serious infection:
  • fever with or without shivers or the chills
  • fever with chest pain and cough
  • fever with high heart rate
  • headache and fever
  • confusion
  • clammy skin
  • fever and a rash
  • fever with breathlessness or fast breathing
  • headache with nausea or vomiting
  • headache with a stiff neck or stiff back
  • body aches with flu-like symptoms
  • eyes sensitive to light
Your healthcare provider will give you a Patient Safety Card about the risk of serious infections. Carry it with you at all times during treatment and for 2 months after your last dose of EMPAVELI. Your risk of serious infections may continue for several weeks after your last dose of EMPAVELI. It is important to show this card to any healthcare provider who treats you. This will help them diagnose and treat you quickly.
EMPAVELI is only available through a program called the EMPAVELI Risk Evaluation and Mitigation Strategy (REMS). Before you can take EMPAVELI, your healthcare provider must:
  • enroll in the EMPAVELI REMS program
  • counsel you about the risk of serious infections caused by certain bacteria
  • give you information about the symptoms of serious infections
  • make sure that you are vaccinated against serious infections caused by encapsulated bacteria and that you receive antibiotics if you need to start EMPAVELI right away and you are not up to date on your vaccines
  • give you a Patient Safety Card about your risk of serious infections, as discussed above
