So I do not use medications if they are not stored at the proper temperatures.. especially injectables. However my lasix slightly froze while sitting in my truck at a race. I thought it'd be fine because it was 35 degrees.  well unfortunately it wasn't. I looked at it and it had floaters because it was starting to freeze. Do I myjust throw it away or thaw it out??? I absolutely do not want to use it if it changes the effectiveness or composition of the lasix.  

I would call your vet just to double check. It’s cheap enough that if you did pitch it, not that big a deal. My Lasix got HOT once and turned brown. Vet said to pitch it. Lpl

yes it's cheap enough. but I'm not at home and guess I'm going to have ro pawn some off of someone.
