Interferon beta medications are used to treat multiple sclerosis (MS). They help slow the progression of certain types of MS, but it's not entirely clear how they work. Interferon beta medications are usually given as injections. Examples include interferon beta-1a (Avonex, Rebif), interferon beta-1b (Betaseron, Extavia), and peginterferon beta-1a (Plegridy).

Copaxone (glatiramer acetate) is an immunomodulator used to reduce the frequency of relapses in patients with multiple sclerosis (MS). It is not an interferon, but may be grouped with interferon betas Avonex and Betaseron; together the three first-line treatments are sometimes known as the "ABC" drugs for MS. The exact mechanism of action of Copaxone in patients with MS is unknown. A generic form of glatiramer acetate is also available under the name Glatopa, but only for the once-daily injection.
