Plegridy Information

The only interferon beta for relapsing MS you inject once every 2 weeks

PLEGRIDY (peginterferon beta-1a) is an interferon for people with relapsing forms of MS. PLEGRIDY can help reduce relapses, delay the progression of physical disability, and reduce brain lesions on MRI.

Pegylation is what makes PLEGRIDY different.

Pegylation is a process that allows the molecule to stay in your body longer.

A polyethylene glycol, or "PEG," chain is attached to the molecule. This increases the size and lengthens the amount of time the molecule can last in the body.

 Polyethylene glycol (PEG) is added to make interferon last longer in the body.
