No worries!
They were likely just trying to make it easy to remember/ easier to explain to each patient instead of giving the various storage options every time. And to make sure you don't accidentally destroy any doses of medication as it is expensive and hard to replace.
Room temperature is fine but any place where it could get significantly warmer, (in a car during spring/summer, in direct sunlight, on your bathroom counter where you take hot steamy showers, etc) can cause damage much faster. I would still recommend a cold pack when driving long distances just in case it gets left in the car for a bit.
