How long are you going to be gone for? If not more than a week to 10 days, I wouldn’t pack any of it with me, simply not worth the hassle. Missing a dose or two won’t affect you that much.
If you’re going to be gone for an extended time, I’d pack some sort of insulated cooler or water bottle holder with one of the cold packs or whatever. That should keep it cold for a pretty good while.
