Receiving ravulizumab-cwvz injection may increase the risk that you will develop a meningococcal infection (an infection that may affect the covering of the brain and spinal cord and/or may spread through the bloodstream) during your treatment or for some time afterward. Meningococcal infections may cause death in a short period of time. You will need to receive a meningococcal vaccine at least 2 weeks before you begin your treatment with ravulizumab-cwvz injection to decrease the risk that you will develop this type of infection. If you have received this vaccine in the past, you may need to receive a booster dose before you begin your treatment. If your doctor feels that you need to begin treatment with ravulizumab-cwvz injection right away, you will receive your meningococcal vaccine as soon as possible and take an antibiotic for 2 weeks.
Even if you receive the meningococcal vaccine, there is still a risk that you may develop meningococcal disease during or after your treatment with ravulizumab-cwvz injection. If you experience any of the following symptoms, call your doctor immediately or get emergency medical help: headache that comes along with nausea or vomiting, fever, a stiff neck, or a stiff back; fever; rash and fever; confusion; muscle aches and other flu-like symptoms; or if your eyes are sensitive to light.
Tell your doctor if you have fever or other signs of infection before you begin your treatment with ravulizumab-cwvz injection. Your doctor will not give you ravulizumab-cwvz injection if you already have a meningococcal infection.
Your doctor will give you a patient safety card with information about the risk of developing meningococcal disease during or for a period of time after your treatment. Carry this card with you at all times during your treatment and for 8 months after your treatment. Show the card to all healthcare providers who treat you so that they will know about your risk.
A program called Ultomiris REMS has been set up to decrease the risks of receiving ravulizumab-cwvz injection. You can only receive ravulizumab-cwvz injection from a doctor who has enrolled in this program, has talked to you about the risks of meningococcal disease, has given you a patient safety card, and has made sure that you received a meningococcal vaccine.
