Would you use a wormer that's a month out of date?

[HelenBack]

I've just had my horse tested and he needs worming. I have a wormer that would be suitable but it's been there for a while and when I checked it expired last month. Not sure whether to chance still using it as I know a lot of things are still okay really after the expiry date, or whether I should just chuck it and buy a new one.

What would others do in this situation?

I would use it, there is usually a wide margin of error

 

[Gloi]

If it had been well stored I'd use it.

 

[HelenBack]

Thanks both. That was my thinking too. It's been kept in a cool, dry place and is still in the packaging so hopefully it will be okay.

Yes, when they withdrew Equitape I talked to my vet and they said as long as stored properly I was fine to buy and keep for the following spring.

Another who’d be happy to use.

Of course it'll be OK. Those Use By dates are rather arbitrary.

 

[HelenBack]

Well that was what I thought too but I just wanted to check in case somebody knew better than me.

Yep, I used a sedalin 12 months out of date. Still effective.

I'd be happy to use it but I would be sure to overdose by 100kg or so.

I would use, as others have said there is a very wide margin on use/sell by dates.

And at least with sedalin you get to tell easily that it's still working! I guess the worst that will happen with the wormer is it won't be effective and he'll need doing again but that could happen anyway.

Thanks, I always give a bit more anyway to account for weight changes and bits getting spat out etc.

Doesnt hurt to occasionally do a second worm count a few weeks after a worming to check for resistance .This could be a good time to do this. Personally ,I think its fine to use the stuff.
