Hi, I've recently started taking Peginterferon alfa-2a, and I keep it in my fridge because that's what the instructions say. I'm going to visit my girlfriend in Scotland a week tomorrow. My journey is going to take two days, so I'll leave home on Saturday morning, stay in a hotel halfway on Saturday night and get to my girlfriend's flat on Sunday afternoon. When I get there I can keep my interferon in her fridge until I use it the following Thursday (because that's my day when I take it). This means my interferon will be out of the fridge for about 30 hours.
So is it safe for my interferon to be unrefrigerated for this amount of time, and if not, can someone recommend an inexpensive, effective way of keeping it cool? I can see there are lots of coolbag products online but I don't know how effective these are for interferon. Also, I've seen an old post on this site suggesting that it might not be safe to take it out of the fridge and allow it to warm up and then put it back in the fridge later.
I'd be grateful for any advice. Thanks.
