A member asked:

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

A doctor has provided 1 answer

# 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).
