Bkemv (eculizumab) is a complement inhibitor. It blocks the complement system, which is part of your immune system.
- For PNH: It helps protect red blood cells from being broken down too early.

Risks and warnings for Bkemv (eculizumab)
Bkemv (eculizumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Serious meningococcal infections
Bkemv (eculizumab) can raise your risk of severe meningococcal infection. This is a fast-moving infection that can lead to meningitis or blood infection and can become life-threatening in a short time. Even if you’ve had your meningitis vaccines, this risk doesn’t go away fully.
Your prescriber should make sure your meningococcal vaccines are up to date before you start Bkemv (eculizumab). If treatment can’t wait, you’ll need vaccines as soon as possible and you might also need antibiotics for a period of time. Call for help right away if you have fever, rash, a stiff neck, bad headache, nausea, vomiting, confusion, or eyes that are sensitive to light. Your care team will keep watching for these symptoms during treatment.
Because of this risk, Bkemv (eculizumab) is available only through a special FDA safety program called the BKEMV REMS. Before you start treatment, your prescriber will enroll you in the program, discuss this risk with you, and give you a Patient Safety Card to carry during treatment and for 3 months after your last dose.
Risk of other serious infections
Bkemv (eculizumab) can also raise your risk of other serious bacterial and fungal infections because it affects part of your immune system. Your prescriber might recommend certain vaccines before you start treatment. Tell your care team right away if you have a fever, chills, cough, trouble breathing, severe sore throat, or other signs of infection.
Problems after stopping treatment
- Risk factors: PNH | aHUS
Don't stop Bkemv (eculizumab) without talking to your prescriber. Stopping treatment can cause your condition to come back or become worse.
Your risk depends on the condition being treated:
- For PNH: Stopping the medication can cause your red blood cells to break down too quickly. Your care team will monitor you for at least 8 weeks after your last dose.
- For aHUS: Stopping the medication can cause serious blood clotting problems called thrombotic microangiopathy (TMA). Your care team will monitor you for at least 12 weeks after your last dose.
Tell your care team right away if you have chest pain, trouble breathing, confusion, dark urine, swelling, seizure, signs of a blood clot, or symptoms of a stroke.
Infusion reactions
Bkemv (eculizumab) can cause infusion-related reactions, including serious allergic reactions like anaphylaxis. Your care team will monitor you during the infusion and for at least 1 hour after each infusion. Tell them right away if you have chest pain, trouble breathing, swelling of your face or throat, dizziness, or feel like you might faint during or after your infusion. If needed, they might slow or stop the infusion and treat your symptoms.
