What happens to avonex (interferon beta-1a) if at room temperature for 24 hours?

Answer 1

i take avonex. out of refrigeration for 24 hours? it is totally useless and a waste of $500.00. avonex is supposed to be refrigerated and only out of the fridge long enough to warm to body temp for injection. the longest mine has ever been out of refrigeration was 4 hours when our power went out, but i had it in a cooler on ice.
after 12 hours of no refrigeration, again, it is useless and a waste of $500.00 for 1 shot. but, there are 2 kinds of avonex, i use the prefilled syringe. there is also the kind that has to be mixed. i assume that you are talking about the prefilled syringe.

Answer 2

I have taken Betaseron for years and a couple of years ago they finally developed a type that doesn't require refrigeration. It sure makes traveling, etc easier. Maybe the Avonex folks will soon develop a type not requiring refrigeration - you might want to contact them and ask about this. After all they are both interferons so it sounds likely. Good Luck.

Answer 3

the presyringed type is less stable. Therefore the potency has been reduced. The precise amount of reduction of the potency depends on the maximum temperature obtained. You should by the lyophilized stuff, or get a generator
