What is the most important information I should know about ULTOMIRIS?
ULTOMIRIS is a medicine that affects your immune system. ULTOMIRIS may lower the ability of your immune system to fight infections.

• ULTOMIRIS increases your chance of getting serious meningococcal infections caused by Neisseria meningitidis bacteria. Meningococcal infections may quickly become life-threatening or cause death if not recognized and treated early.
  • You must complete or update your meningococcal vaccine(s) at least 2 weeks before your first dose of ULTOMIRIS.
  • If you have not completed your meningococcal vaccines and ULTOMIRIS must be started right away, you should receive the required vaccine(s) as soon as possible.
  • If you have not been vaccinated and ULTOMIRIS must be started right away, you should also receive antibiotics to take for as long as your healthcare provider tells you.
  • If you had a meningococcal vaccine in the past, you might need additional vaccines before starting ULTOMIRIS. Your healthcare provider will decide if you need additional meningococcal vaccines.
  • Meningococcal vaccines do not prevent all meningococcal infections. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a serious meningococcal infection:

• enroll in the ULTOMIRIS and SOLIRIS REMS program
• counsel you about the risk of serious meningococcal infections
• give you information about the signs and symptoms of serious meningococcal infection
• make sure that you are vaccinated against serious infections caused by meningococcal bacteria and that you receive antibiotics if you need to start ULTOMIRIS right away and you are not up to date on your vaccines
• give you a Patient Safety Card about your risk of meningococcal infection, as discussed above

• If your child is treated with ULTOMIRIS, your child should receive vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib).
• Certain people may be at risk of serious infections with gonorrhea. Talk to your healthcare provider about whether you are at risk for gonorrhea infection, about gonorrhea prevention, and regular testing.

• adults and children 1 month of age and older with a disease called Paroxysmal Nocturnal Hemoglobinuria (PNH).
• adults and children 1 month of age and older with a disease called atypical Hemolytic Uremic Syndrome (aHUS).
  ULTOMIRIS is not used in treating people with Shiga toxin E. coli related hemolytic uremic syndrome (STEC-HUS).
• adults with a disease called generalized Myasthenia Gravis (gMG) who are anti-acetylcholine receptor (AChR) antibody positive.
• adults with a disease called Neuromyelitis Optica Spectrum Disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive.

• have an infection or fever.
• are pregnant or plan to become pregnant. It is not known if ULTOMIRIS will harm your unborn baby.
  • Pregnancy Registry: There is a registry for pregnant women who take ULTOMIRIS. The purpose of this registry is to check the health of the pregnant mother and her baby. If you are pregnant or become pregnant while taking ULTOMIRIS, talk to your healthcare provider about how you can join this pregnancy registry or you may contact the registry at 1-833-793-0563 or www.UltomirisPregnancyStudy.com to enroll.
• are breastfeeding or plan to breastfeed. It is not known if ULTOMIRIS passes into your breast milk. You should not breastfeed during treatment and for 8 months after your final dose of ULTOMIRIS.

• Your healthcare provider will decide how long you need to receive ULTOMIRIS for your PNH, your aHUS, your gMG, or your NMOSD.

• You will be given intravenous ULTOMIRIS infusion by a healthcare provider through a needle placed in a vein
• You will usually receive:
  • a starting dose of intravenous ULTOMIRIS infusion by your healthcare provider, and then
  • 2 weeks later, you will start to receive an infusion of ULTOMIRIS every 8 weeks.

• Your child will usually receive:
  • a starting dose of intravenous ULTOMIRIS infusion by your healthcare provider, and then
  • your healthcare provider will decide how often your child will receive their intravenous ULTOMIRIS infusion, either every 4 weeks or every 8 weeks, depending on their weight, starting 2 weeks after the starting dose.

• After each administration, you should monitor for infusion-related reactions for at least 1 hour. See "What are the possible side effects of ULTOMIRIS?"
• If you have PNH and you stop receiving ULTOMIRIS, your healthcare provider will need to monitor you closely for at least 16 weeks after you stop ULTOMIRIS. Stopping ULTOMIRIS may cause breakdown of your red blood cells due to PNH.
  Symptoms or problems that can happen due to red blood cell breakdown include:

• If you have aHUS, your healthcare provider will need to monitor you closely for at least 12 months after stopping treatment for signs of worsening aHUS or problems related to a type of abnormal clotting and breakdown of your red blood cells called thrombotic microangiopathy (TMA).
  Symptoms or problems that can happen with TMA may include:
