Betaseron

Betaseron (interferon beta-1b) is an immunomodulatory medication used to treat relapsing forms of multiple sclerosis (MS). It helps reduce the frequency of MS relapses and slows the progression of physical disability. Betaseron works by modifying the immune response and reducing inflammation in the central nervous system.

Benefits

• Suitable for long-term disease management

Dosage

• Adults with relapsing MS: 250 micrograms (0.25 mg) injected subcutaneously every other day
• Injections should be rotated between different body sites to reduce skin reactions
