liquid Cypro and expiration date?
Marc Davis <lmdavis@...>
My horse has been on the liquid Cypro for 4 months now. In the beginning it
was working well, however, in the last three weeks he has started to show
some "changes" that make me wonder if he is not responding to Cypro any
more. I'm also wondering if since the expiration date on my bottle is up in
July maybe it actually loses effectiveness sooner than what the producer
thinks? Anyone have any experiences here?
Carla, Only know from being a nurse and with expiration dates on "Human
Meds" -- for sure they do not lose their "power" before the exp. date. In
fact, many of the meds that are "outdated" or "have expired" (somehow I hate
speaking of anything or anyone in those terms, a nurse thing too, I am sure)
can be safely used for quite a long time after that date. Yeah, that is a
"well kept secret." So I would say, "NO, it wouldn't be because you are
nearing the exp. date." and "YES, that's my FINAL ANSWER."
Anyone else have any pros or cons with the liquid? I know it is cheaper, I
know it is easier, my question is -- is it doing as good a job? I am not
sure about that myself! Kay, who just wishes she knew more about this stuff
All I know is that Kay is exactly right, the majority of meds are
effective well after expiration dates... and I've heard that
generally if a pill looks the same color it always did, isn't
crumbling or falling apart or changing color, etc, its probably
I know pills (solid) last the longest past expiration dates -- often
YEARS past. Gel caps not nearly as well or as long, they'll 'die'
sooner and are a bit more risky to use past expiration. Liquids &
liquid suspensions (like the cypro) go quickest, often in a matter of
a few months, but still generally roughly twice the expiration date.
Personal experience -- I had some gel caps for pain (herniated disk)
that I accidently left in the truck for a few hours... they were
TOTALLY inactivated after that, absolutely worthless. Um, it WAS
about 108 or 110 that day... in the truck, betcha 120 or higher...
So you may want to check the storage directions and be sure it hasn't
gotten too hot or cold...
I'd be much more suspicious, however, that he's just starting to not
respond to it as well... again, check with BET labs, they told me if
he's NOT producing enough thyroid, the cypro won't work or won't work
well, so you may just need to add some thyrol-l...
