What is the most important information I should know about FABHALTA?

FABHALTA is a medicine that affects part of your immune system and may lower your ability to fight infections.

• FABHALTA increases your chance of getting serious infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type b. These serious infections may quickly become life threatening or fatal if not recognized and treated early.
  • You must complete or update your vaccinations against Streptococcus pneumoniae and Neisseria meningitidis at least 2 weeks before your first dose of FABHALTA.
  • If you have not completed your vaccinations and FABHALTA must be started right away, you should receive the required vaccinations as soon as possible.
  • If you have not been vaccinated and FABHALTA must be started right away, you should also receive antibiotics to take for as long as your health care provider tells you.
  • If you have been vaccinated against these bacteria in the past, you might need additional vaccinations before starting FABHALTA. Your health care provider will decide if you need additional vaccinations.
  • Vaccines do not prevent all infections caused by encapsulated bacteria. Call your health care provider or get emergency medical care right away if you have any of these signs and symptoms of a serious infection:
    • Fever with or without shivers or chills
    • Fever with chest pain and cough
    • Fever with high heart rate
    • Headache and fever
    • Confusion
    • Clammy skin
    • Fever and a rash
    • Fever with breathlessness or fast breathing
    • Headache with nausea or vomiting
    • Headache with stiff neck or stiff back
    • Body aches with flu-like symptoms
    • Eyes sensitive to light

Your health care provider will give you a Patient Safety Card about the risk of serious infections. Carry it with you at all times during treatment and for 2 weeks after your last dose of FABHALTA. Your risk of serious infections may continue for a few weeks after your last dose of FABHALTA. It is important to show this card to any health care provider who treats you. This will help them diagnose and treat you quickly.

FABHALTA is only available through a program called the FABHALTA Risk Evaluation and Mitigation Strategy (REMS). Before you can take FABHALTA, your health care provider must:

• Enroll in the FABHALTA REMS program.
• Counsel you about the risk of serious infections caused by certain bacteria.
• Give you information about the symptoms of serious infections.
• Make sure that you are vaccinated against serious infections caused by encapsulated bacteria and that you receive antibiotics if you need to start FABHALTA right away and you are not up to date on your vaccinations.
• Give you a Patient Safety Card about your risk of serious infections.

Who should NOT take FABHALTA?

Do not take FABHALTA if you:

• Are allergic to FABHALTA or any of the ingredients in FABHALTA.
• Have a serious infection caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, or Haemophilus influenzae type b when you are starting FABHALTA.

Before you take FABHALTA, tell your health care provider about all your medical conditions, including if you:

• Have an infection or fever.
• Have liver problems.
• Are pregnant or plan to become pregnant. It is not known if FABHALTA will harm your unborn baby.

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking FABHALTA with certain other medicines may affect the way FABHALTA works and may cause side effects.

Know the medicines you take and the vaccines you receive. Keep a list of them to show your health care provider and pharmacist when you get a new medicine.

For people with PNH:

• If you stop taking FABHALTA, your health care provider will need to monitor you closely for at least 2 weeks after stopping FABHALTA. Stopping FABHALTA may cause a breakdown of red blood cells due to PNH. 
  
  Symptoms or problems that can happen due to breakdown of red blood cells include:
  • Decreased hemoglobin level in your blood
  • Blood in your urine
  • Shortness of breath
  • Trouble swallowing
  • Tiredness
  • Pain in the stomach (abdomen)
  • Blood clots, stroke, and heart attack
  • Erectile dysfunction
• It is important that you take FABHALTA exactly as your health care provider tells you to lower the possibility of breakdown of red blood cells due to PNH.

What is FABHALTA?  
FABHALTA is a prescription medicine used to:

• Treat adults with paroxysmal nocturnal hemoglobinuria (PNH).
• Reduce protein in the urine (proteinuria) in adults with primary immunoglobulin A nephropathy (IgAN), who are at risk of their disease progressing quickly.

FABHALTA is approved based on a reduction of proteinuria. Continued approval may require results from an ongoing study to determine whether FABHALTA slows decline in kidney function. 

It is not known if FABHALTA is safe and effective in children with PNH or IgAN.
