thanks to everyone! now i'm really relieved!
Make sure it's in moisture tight containers.
i keep levothyroxin in the fridge all the time
I've heard of some people keeping their thyroid medications in the fridge or freezer, but you must make sure the containers are completely sealed or that they are placed inside sealed containers so that moisture does not enter the bottles and ruin the pills. Moisture would damage the pills more quickly than heat, I think.
