Is Expired Tetracycline OK?

Recommended Posts

Sara would probably be the best one to answer this categorically, but I would hazard a guess and say it would be safer not to use it...in the human world, drugs past their use by date are disposed of, at least in the hospitals I used to work in - no longer seen as safe and fit for human consumption.

It may all be a load of marketing genius by the pharmaceutical giants to get people to buy more regularly, but who would want to take the risk...

My understanding is that use by dates are an 'indication' of when the drug will no longer be useful. However in our store we will not use drugs in our tanks that are past their use by date, on instruction from our fish vet.

Better safe than sorry?

A best before date is an indicator. A used by date is where the pharmaceutical companies legal obligations end.

Thanks for the clarification Brenton :-)

Either way, we don't use it after that date. With the amount of fish we have in a bay, it's just not worth the risk.

Thanks for the answers.

I just found some info online saying that expired tetracycline can go toxic.

Apparently other antibiotics are usually 90% effective for quite a while after the use by date.
