Pharma Jellies out there: does freezing a medication (in pill form) cause it to lose its efficacy?

I’m no authority, but my son has acquired a lot of pharmaceutical knowledge through independent study, and he maintains that freezing pills prolongs their period of effectiveness.

Thanks, @Jeruba , I was hoping so! I have no idea if the freezing process alters the chemical composition of the stuff…

That’s good to know, because I habitually freeze my pharma.

I can’t state which ones, but several, when I was very sick, had to be maintained within a certain temp range. Before you guess, talk to the pharmacist!
