It's 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.

All though I am past the beginning stages of my MS treatments, this sounds like a decent alternative to Copaxone if you are allergic to it…and it's a subcutaneous injection only! The AutoInjector can handle this with ease…good product! jefff

EXTAVIA is effective, and proven to delay the second episode in patients with clinically isolated syndrome (CIS). It has been shown to reduce the rate of moderate-to-severe relapses. The recommended dose of is 0.25 mg taken every other day through manual injection or with the EXTAVIA Auto-Injector II. It does not need to be refrigerated as an unmixed powder. After mixing however, it must be used right away or refrigerated and used within 3 hours…EXTAVIA is administered subcutaneously just under the skin using a short needle.


EXTAVIA is a prescription medicine, so if you're allergic to interferon beta-1b or another interferon beta, do not take. Also do not take if allergic to human albumin or mannitol.

Other issues are liver problems, eye yellowing, itchy skin, a felling of being very tired/drowsy, flu-like symptoms, nausea, vomiting, bruising easily, bleeding problems, breathing issues, swallowing issues, swelling of the mouth/tongue, rash, depression, anxiety, and skin bumps.

There is also an issue with a low white blood cell count.
