EXTAVIA (interferon beta-1b) is a prescription medication approved for the treatment of relapsing forms of multiple sclerosis (MS) to reduce the frequency of episodes. EXTAVIA is also for patients who have had a single episode and MRI findings consistent with MS.
Why Use EXTAVIA to Treat Multiple Sclerosis?
Your doctor may recommend EXTAVIA for several reasons. Here are a few:
EXTAVIA is effective.
- EXTAVIA is proven to delay the second episode in patients with clinically isolated syndrome (CIS)
- EXTAVIA has been shown to reduce the rate of moderate-to-severe relapses
- The recommended dose of EXTAVIA is 0.25 mg taken every other day through manual injection or with the EXTAVIA Auto-Injector II
EXTAVIA doesn't need to be refrigerated as an unmixed powder. After mixing, however, EXTAVIA must be used right away or refrigerated and used within 3 hours.
EXTAVIA is administered subcutaneously.
EXTAVIA is administered just under the skin using a short needle.
