Betaseron® (interferon beta-1b) is a purified, sterile, lyophilized protein product produced by recombinant DNA techniques. Rebif is taken three times per week by subcutaneous injection, while Betaseron is injected every other day. Betaseron has a broader indication than Rebif. Click here to learn more.
