Ethically speaking not without a vet signing off on it, and I doubt a vet would because they can’t be sure of the providence/authenticity of the drug, if it had been switched by some other drug, etc, despite it being in a commercially marked container. Once a drug is out of the recognized mainstream of distribution, it becomes problematic for passing it on. I would hazard a strong suspicion that all “surrendered” drugs are quietly destroyed for just such a reason, and not recycled.
However, giving it away shouldn’t be illegal because it isn’t a controlled substance.
Bute and banamine are about the only equine drug I’d share, or borrow, or “lend” (give away) without a second thought to another horse owner because they are such a common, long standing, often used arsenal in the equine medicine chest. This drug, however, is a slightly different story as it isn’t in common use in horses as it wasn’t developed for equines in mind, and thus wouldn’t be found in the everyday equine medicine box. So the probability of casually bumping into another horse person that has a need for this medication is slim to null. I’d have to actively ask around, and I’m reluctant to do so.
I also want to venture a guess: is the medication Isoxuprine?
Sorry, but no.
And to the suggestion of talking to my vet: I have done so. Not happy with the response. (Basically a shoulder shrug) Therein lies my issue of what to do to be rid of this expensive med that isn’t needed or wanted and will not be used for any of my other animals.
Thanks to everyone that posted suggestions. I sincerely appreciate your thoughts. I believe I will talk to my local pharmacy (as this medication is human grade) and see what they recommend.
