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

PEMGARDA may cause serious side effects, including:

  • A serious allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and can happen during or after your infusion of PEMGARDA. In case you have a severe allergic reaction to PEMGARDA and need medical help right away, you will receive PEMGARDA in a healthcare setting. Your healthcare provider will monitor you for allergic reactions during your infusion and for at least 2 hours after you are finished receiving PEMGARDA. Your healthcare provider will stop PEMGARDA right away if you develop signs or symptoms of anaphylaxis or severe allergic reaction. Tell your healthcare provider right away if you get any of the following signs or symptoms of anaphylaxis during or after your infusion of PEMGARDA:
  • itching
  • flushing
  • hives
  • skin redness
  • swelling of your face, lips, mouth, tongue, throat, hands, or feet
  • sweating
  • dizziness
  • ringing in the ears
  • wheezing
  • trouble breathing
  • chest discomfort
  • fast heartbeat

What should I tell my healthcare provider before I receive PEMGARDA?

Tell your healthcare provider about all of your medical conditions, including if you:

  • have any allergies, including if you have had a severe allergic reaction to a COVID-19 vaccine or PEMGARDA.
  • are pregnant or plan to become pregnant. It is not known if PEMGARDA can harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if PEMGARDA can pass into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you receive PEMGARDA.
  • have any serious illnesses.

The side effects of receiving any medicine by vein (IV) may include pain, redness, bleeding, bruising of the skin, soreness, swelling, and possible infection at the infusion site.

The most common side effects in people treated with PEMGARDA who have moderate-to-severe immune compromise include allergic and infusion-related reactions, infusion site reactions, common cold, viral infection, flu-like illness, tiredness, headache, and nausea.

These are not all the possible side effects of PEMGARDA. Not a lot of people have been given PEMGARDA. Serious and unexpected side effects may happen. PEMGARDA is still being studied, so it is possible that all of the risks are not known at this time.
