Hi there,
Tammy is right. But, specifically the guidance says "Room temperature storage up to 30 days, if refrigeration is unavailable"
Note: if refrigeration is unavailable
Personally, I feel this does not include varying room temperatures and I would not advise anyone to leave it out in hi (hot) temperatures. But, that's my personal opinion. Would only feel comfortable to do something like that if I knew the temperatures at which the forumula/medicine would change.
