What is the most important information I should know about EPYSQLI?
EPYSQLI is a medicine that affects your immune system. EPYSQLI may lower the ability of your immune system to fight infections.
- EPYSQLI increases your chance of getting serious meningococcal infections caused by Neisseria meningitidis bacteria. Meningococcal infections may quickly become life-threatening or cause death if not recognized and treated early.
- You must complete or update your meningococcal vaccines at least 2 weeks before your first dose of EPYSQLI.
- If you have not completed your meningococcal vaccines and EPYSQLI must be started right away, you should receive the required vaccine(s) as soon as possible.
- If you have not been vaccinated and EPYSQLI must be started right away, you should also receive antibiotics to take for as long as your healthcare provider tells you.
- If you had a meningococcal vaccine in the past, you might need additional vaccines before starting EPYSQLI. Your healthcare provider will decide if you need additional meningococcal vaccines.
- 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 serious meningococcal infection. Fever, fever with high heart rate, headache and fever, confusion, muscle aches with flu-like symptoms, fever and a rash, headache with nausea or vomiting, headache with a stiff neck or stiff back or eyes sensitive to light.
Your healthcare provider will give you a Patient Safety Card about the risk of serious meningococcal infection. Carry it with you at all times during treatment and for 3 months after your last dose of EPYSQLI. Your risk of meningococcal infection may continue for several weeks after your last dose of EPYSQLI. It is important to show this card to any healthcare provider who treats you. This will help them diagnose and treat you quickly.
EPYSQLI is only available through a program called the EPYSQLI Risk Evaluation and Mitigation Strategy (REMS). Before you can receive EPYSQLI, your healthcare provider must:
- enroll in the EPYSQLI REMS program
- counsel you about the risk of serious meningococcal infections
- give you information about the signs and symptoms of serious meningococcal infection
- make sure that you are vaccinated against serious infections caused by meningococcal bacteria and that you receive antibiotics if you need to start EPYSQLI right away and you are not up to date on your vaccines
- give you a Patient Safety Card about your risk of meningococcal infection, as discussed above
EPYSQLI may also increase the risk of other types of serious infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria gonorrhoeae.
- If your child is treated with EPYSQLI, your child should receive vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib).
- Certain people may be at risk of serious infections with gonorrhea. Talk to your healthcare provider about whether you are at risk for gonorrhea infection, about gonorrhea prevention, and regular testing.
- Certain fungal infections (aspergillus) may also happen if you take EPYSQLI and have a weak immune system or a low white blood cell count.
