My neuro likes to keep patients on the 22mcg dose longer than the 2 weeks in the
titration pack, to get acclimated to the med. Ask your doc about that.
My neuro tests for liver, etc bloodwork at 3, 6, & 9 months -- I asked for more frequent tests -- monthly for the first 6 months.
I also have thyroid disease, take Lipitor, and have a history of depression, so had some extra fears about taking Rebif -- but so far, no problems there.
