Multiple: Avonex (interferon beta 1a) is an interferon, given into the muscle once weekly, and copaxone, injected under skin daily, is a polymer. But why use needles, as we have 3 oral agents, and all are as potent or more potent than Avonex (interferon beta 1a) and copaxone.

Avonex (interferon beta 1a) v Copaxone: Avonex (interferon beta 1a) is an injection given to a muscle once per week. It is a deep shot. Copaxone is a superficial shot given under the skin every day. The retail costs of the medicines are about the same. They are both expensive; insurance coverage may be important. Avonex (interferon beta 1a) sometimes may cause flu-like side effect symptoms, copaxone may not. Both can cause irritation by the injection site.

What's the difference between the MS drugs avonex (interferon beta 1a) and copaxone?

# OF INJECTIONS: Both Avonex and Copaxone are drugs of the 90's, and have helped numerous pts. Copaxone is injected daily, does have injection rxtns, yet is considered safer for pregnancy. Avonex is injected once weekly, but can cause flu rxtns, depression, thyroid and liver issues, and is not safe for pregnancy. Both are modestly effective, but many newer agents have better outcomes (tysabri, gilenya, (fingolimod) etc).
