Just as the title says, In what circumstance did you use Panacur PowerPac? I have a horse coming back from 6 months off in a herd and wonder if its a good first step.

Have a fecal done first.
Definitely a FEC first. Do you know anything about the 6 months?
Hoping to solve chronic diarrhea in a young horse I owned. Didn’t work.
If we assume nothing has been done for 6 months, then we assume tapeworms and bots are a problem. A PP won’t touch either of those.
So, even if you opt to not do a FEC (but that really is ideal) then I’d start with Equimax. Then do a FEC in 12 weeks.
If you are afraid of a high load, and a resulting large die-off, then do a double dose of Safeguard/Panacur to kill some (likely) small %, then in 2 weeks do Equimax (or Quest Plus if the weight is good and you have a good handle on the weight).
There’s just not as much value in a PP these days as there was, due to resistance issues.
My mare had a high FEC count last year, and we used a Power Pac to knock the count down approximately 50%, took another FEC to see where we were, then followed up with Quest Plus. A final FEC showed we had cleared the issue. The vet told me a single or double one time dose of Panacur would be useless to knock the count down in any meaningful way before we got out the big guns. The Power Pac is a great way to lower the count with a low risk of impaction from die off.

Unless you do a FECRT, you can’t say for sure of that. While pyrantel pamoate does have big resistance issues, it’s lower than fenbendazole.
On my farm, fen is useless, but pyrantel pamoate is about 90% effective in a single dose.
So while you did find out that pp isn’t very effective on your farm (imagine how little would have been done with a single dose, or a one-time double dose if a the whole PP only took care of 50%!), you wouldn’t have known that without a FECRT.
So in my case, without knowing, a PP would have killed off almost all that very high count.
Thanks so much.
A point for everyone to consider is that impaction due to die off is a concern with ascarids (roundworms). It’s not a major concern with small strongyles because of the difference in size of the adult parasites and also the size of the horse likely to have the parasites. A foal, with it’s small overall size, is much more likely to have an issue with impaction with ascarids which are large worms. Adult horses generally are resistant to ascarids.
It is also wise to keep in mind that resistances are region specific. In this area, the widespread use of old school Strongid C has made any form of pyrantal useless. I used it. EVERYBODY used it.
On another note, my mare also had pneumonia, and I was not taking any chances. She was NQR for a few days which prompted the fecal, and not 2 days after it was pulled, spiked a high fever. She was VERY sick, and we did not want to stress her more than needed after getting the fever under control.
Just pull the FEC and talk to your vet. They know what works in your area.
But it was widely used here too (SE area) and my farm does not have a resistance to pyrantel pamoate.
