BE VERY CAREFUL ABOUT EXPIRATION DATES OF THESE TWO ANTIBIOTICS……TETRACYCLINE AND DOXYCYCLINE.

DO NOT USE THEM IF THEY ARE EXPIRED.

ONCE EXPIRED THEOR CHEMICAL STRUCTURE CHANGES AND CAN EASILY HARM YOU.

The other antibiotics do not show this sort of change when the expiration date comes and goes.

I always tell people to store their bottles of antibiotics inside small glass canning jars with a tightly affixed lid and ring, and then place those jars on your cool cement basement floor. You can throw moisture absorbing packets into each jar also, but of you carefully tightly seal the ring and lid, no moisture should get in.

The temperature on a cement basement floor, in my part of the country, stays at 65 degrees. I have placed small thermometers on the floor and monitored the temp regularly…..it never varies. That is an ideal temperature for preserving the integrity of your antibiotics. Just be sure you place the bottles inside sealed glass jars.

The military did a study looking at the safe she

F life of all the drugs they purchase and were THROWING AWAY WHEN THE MEDS EXPIRED…….HORRIFIC WASTE. They found that if you store the medication on a controlled temp/ humidity environment , which is what you achieve when you put the bottles inside glass jars with a canning lid and ring and moisture absorber, the life of the medication is extended greatly. So I suggest you stock up on some new canning jars that come with lids and rings, get some moisture absorbers, and safely store the meds you buy.

I had an unused, just "expired", doxycycline prescription going into covid-19. With its covid-19 treatment potential, per Dr Zelenko, I searched a bit. Found https://www.fda.gov/it/media-base/147142/download

The FDA has been testing lots of doxycycline in the national stockpile (doxycycline is stockpiled for a bioterrorism countermeasure in "their" / not available to us? national stockpile )

for example a lot with a March 31, 2015 expiration was extended twice, for use till July 31, 2022. extended again? I seem to remember reading of their considerations against that but those do not show up in my quick search for reference.

somewhat weakened antibiotics is one thing. Killing your kidney function with toxic / gone bad antibiotics is another, (there is remdesivir for that).

Good tip on storage, thank you.
