HOW Plegridy® WORKS
Plegridy® is a long-acting interferon. Interferons are proteins occurring naturally in the immune system. Plegridy® is thought to reduce inflammation and impede the immune response of attacking the body’s own myelin.
FDA-Approved
Plegridy® was FDA-approved in 2014 to treat relapsing forms of MS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary-progressive disease, in adults.
Potential Side Effects
Flu-like symptoms, injection-site skin reaction, depression, white blood cell count and liver test abnormalities. Serious potential adverse events include liver failure. Potential side effects are usually temporary and manageable. Blood tests can monitor liver enzymes, blood-cell counts, and neutralizing antibodies.
