hey star,
best wishes w/ Humira. i fancied the the regular syringes, personally the "slower" i injected the med (abdomen always) the less it STUNG! burns like a mother! {sorta' like the bigger Enbrel doses. (wow Enbrel...seems like sooo long ago!).
i was on Enbrel for 2 yrs and Humira for 2 years.
never had any significant reaction from either. of course some anemia & low wbc's...but nothing scary.
serum sickness is a nightmare. luckily my GI didn't d/c the Remicade after that happened last spring. was about my 18th infusion by then.
they stopped the IV, ran saline, gave a bunch of meds to counteract the infusion reaction....but i continued after that.
hmm...i remember i got super dizzy, nauseous, chest tightening and my BP dipped to 86/60...
my doc has me do this regimen of pre-pre-medicating and "post" medicating for the remicade reactions...4 days on pred, tylenol & benedryl before the remicade and 4 days after.
i feel you'll do fine w/ the Humira. when does your 1st shipment come? best wishes!
