Vyvgart is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat adults with myasthenia gravis who have a specific type of antibody called anti-acetylcholine receptor antibody. Vyvgart is also referred to by its drug name, efgartigimod alfa-fcab.

Vyvgart is believed to work by sticking to and blocking a protein called the neonatal Fc receptor (FcRn). This protein helps to control the levels of antibodies in the blood. When Vyvgart blocks FcRn, it lowers the levels of harmful antibodies, which helps muscles work better.

How do I take it?
Vyvgart comes in a single-dose vial and is given as a subcutaneous (under the skin) injection. Vyvgart infusions should be administered by a health care professional. Your doctor will prescribe the Vyvgart dosage that’s right for you.
