FREEZING Prescription drugs (Not intentionally)

[Sourdough]

PLEASE don't guess. A guess is worth slightly less than ZERO.

If you are one of those humans who feels compelled to respond but is clueless, please in your response state you have zero idea, but can't control yourself.

It is slightly below zero this morning. This winter 24'-25' it will get -28 to -36 "below" but my prescription drugs are delivered via USPS. If you have professional training, please voice your opinion of potential damage to any class of prescription medication freezing.

Watch this thread as it is nearly assured someone will post that they don't know, but they think (read did not think) freezing prescription medication could harm or degrade them.

Speaking from personal experience, (and I have a PhD in chemical engineering)...

Way back when you could buy a year's worth of prescription drugs at a time, I found that before the year was out the drugs were turning yellow. So I started keeping them in the freezer. In the freezer they kept indefinitely. I've been doing this for decades.
There are SOME drugs like insulin and other injectable drugs that are in a liquid state that you CANNOT freeze, but drugs that are solid, in my experience, will keep just fine in the deep freeze for a long long time. Solid is the key. In capsules or hard pills either one. But it must be solid.
The reason you can't keep liquid drugs in the freezer is that ice crystals form and when that happens it can cause a separation of ingredients (like in ice distillation).
