Good stuff. I have the Fish-Mox, and even tried it once when I thought that I was getting sick. It didn’t seem to affect me either way...not harm, but no improvement - but maybe because I had a virus rather than an infection. But I like the fact that nearly all pills are good for at least 8 years. I’ve been stocking prescriptions for a while, and now use one that is about 2 years old every day (i.e., I have a two-year supply, so, of course, I use the oldest first).
What's the shelf life of unrefigerated insulin?
I don't take it but my wife does.
Doxycycline has a 2 year shelf life. After that, it can turn toxic. Other tetracyclines may be even more toxic after expiration. Expired tetracyclines damage the kidneys.
FWIW, I was once told by a physician that even freeze dried penicillin had a 3-year shelf life.
The pharmacists/clinicians here can comment with more authority.
