What should I discuss with my healthcare provider before receiving ravulizumab?

You will need to receive a vaccine to protect against meningococcal infections at least 2 weeks before you start using ravulizumab. If your child is treated with ravulizumab, make sure he or she is vaccinated against pneumonia and influenza type B (Hib).

If you need to start receiving this medicine before you are vaccinated, you may be given antibiotic medicine to take during the first 2 weeks of ravulizumab treatment.

Tell your doctor if you have recently had any symptoms of infection (fever, chills, or flu-like symptoms).

Tell your doctor if you are pregnant. It is not known whether ravulizumab will harm an unborn baby. However, having PNH during pregnancy may cause complications in the baby or the mother, including blood clots, infections, bleeding, miscarriage, premature delivery, or death. The benefit of treating PNH may outweigh any risks to the baby or the mother.
