I Left My Propecia In the Car Overnight and Everything Froze

Hello,
I live in the midwest and it’s very cold and snowy. A few days ago I accidentally left my Propecia in my car overnight. When I went out the next morning, my water bottle and everything in the car was frozen so it had gotten quite cold the night before. This is the first and only time this has happened. Do you think the rest of the prescription is okay?

I spoke with a rep at Merck about this and was told that freezing may alter the value of Propecia. The safest thing to do is to replace what you are using with fresh medications. Or you can chance it, but that’s entirely up to you.
