Do fish meds expire?

Years ago (over 5) I purchased some fish meds for "just in case". Happily, I have never had to use them. I have looked for expiration dates, but couldn't find any. Does the effectiveness of fish meds lessen in time? Do they become toxic over time? Should I toss them or is it ok to hang on to them?

Thanks!

I would look them up on the website of the company that makes those particular products. It is likely that some types of medication do expire, such as antibiotics.

Just to be safe I would probably replace them once a year.

If the seal is not broken and it was kept in a cool dark place or stored in the proper way and depending on the product...it may or may not still be good.
Some product when expired usually will be inactive, some, however, can become toxic.
As Adastra posted-e-mail/website the company and get more information
But-IMO-when in doubt...throw it out...its not worth it.....

It could be.
The meds I've gotten expire within a year, so I wouldn't trust it if you can't find anymore info.
