Ravulizumab-cwvz may increase your chance of having serious infections, including a meningococcal infection. Avoid people who are sick or have infections. Tell your doctor right away if you or your child develop headaches, nausea, vomiting, fever, a stiff neck or back, rash, confusion, muscle aches, or if your eyes have become sensitive to light. Make sure you have received a vaccine to prevent meningococcus infections at least 2 weeks before you receive this medicine. You may also be given antibiotic medicines for 2 weeks to prevent infections if you are to use this medicine right away. If you have already received the meningococcal vaccine in the past, your doctor will decide if you need another dose.

Ask your doctor for a patient safety card. This card will list the symptoms of meningococcus infections and what to do if you have them. Carry the card with you at all times during treatment and for 8 months after your last dose. You will need to show the card to any doctor who treats you.
