Possible side effects
EMPAVELI is a medicine that can affect your immune system. EMPAVELI can lower the ability of your immune system to fight infections.
- EMPAVELI may increase your chance of getting serious and life‑threatening meningococcal infections. Meningococcal infections may quickly become life‑threatening and cause death if not recognized and treated early.
- EMPAVELI may also increase the risk of getting serious infections. People who take EMPAVELI may have an increased risk of getting infections caused by Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. Serious infections may quickly become life-threatening and cause death if not recognized and treated early.
- You must be vaccinated against these bacteria at least 2 weeks before your first dose of EMPAVELI if you have not already had these vaccines.
It's important to have all your prior vaccination records readily available before starting treatment with EMPAVELI.
- You must be vaccinated against these bacteria at least 2 weeks before your first dose of EMPAVELI if you have not already had these vaccines

- If you have not been vaccinated and EMPAVELI therapy must be started immediately, you should receive 2 weeks of antibiotics with your vaccinations
- If you have been vaccinated against these bacteria in the past, you might need additional vaccinations before starting EMPAVELI. Your healthcare provider will decide if you need additional vaccinations
- Vaccines reduce the risk of serious infections but do not prevent all serious infections
Call your healthcare provider or seek emergency medical care right away if you have any new signs or symptoms of a serious infection:
- fever with or without shivers or the chills

- shortness of breath
- extreme pain or discomfort
- headache with nausea or vomiting

Tell your healthcare provider about all the vaccines you receive and medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements which could affect your treatment.
EMPAVELI REMS program ensures your safety is a top priority
EMPAVELI is only available through a program called the EMPAVELI REMS (Risk Evaluation and Mitigation Strategy).
REMS is a safety program run by the FDA. Before you can take EMPAVELI, your healthcare provider must enroll in the program and will provide you with the following:
- Counseling on the risk of serious infections caused by certain bacteria
- Information about the symptoms of serious infections
- Appropriate vaccinations
- A Patient Safety Card
- Carry this card with you at all times during treatment and for 2 months after your last EMPAVELI dose
- Show this card to any healthcare professional to help diagnose and treat you quickly
- Your risk of serious infection may continue for several weeks after your last dose of EMPAVELI

Before you take EMPAVELI, tell your doctor about all your medical conditions, including if you:
