Humira injection - 2 days early

2-days early should be fine. You want to maintain a stable humira-concentration within your blood, and being a few days early or late does not create an issue. I'd rather be early than late though! I've had remicade infusions rescheduled and been 3 days early/late before and nobody thought a thing of it (my gasteroenteroligist, the infusion nurse, etc.).

you can also take it with you -- the pens can be left at room temp (with no sun exposure) for 14 days.
