5 day panacur

I don't use it as my girl goes all depressed and lethargic for about a week during and after it. I also believe there is now widespread resistance to the active ingredient anyway and there are other drugs available that treat the same worms. I'm by no means an expert though and will be interested to see what others think
 
This is the first time I have used it. Hope my horses will be ok on it. One has pinworm the other is ok, but the vet recommended me doing both as they share the same field
 
It can be a very useful wormer if your horse doesn't have two many resistant worms.

Only moxidectin (Equest) and 5 day Panacur will treat encysted worms. If you don't know whether your horse has resistant worms then be sure to worm count about ten days after the last dose and the egg level should be right down from a previous significant count if it has worked well. (Yes we know encysted worms don't lay eggs but use the adult stages as an indication)
It is also a good treatment for pinworm.
 
A friend used this on her two horses. Both had to be rushed to equine hospital about six hours later with severe colic. One died. The other had to have a big emergency operation. He just about pulled through, too weak to stand for a week, and had to be slowly nursed back to health for the next two months.

Wouldn't touch it with a bargepole.
 
2 out of 7 of ours developed severe urticaria on the 3rd day(one of those 2 also had mild colic symptoms). Vet advised to stop treatment on the 3rd day(when I rang him) and said it was the reaction of those 2horses to the release of the dead worms/toxins from the deceased worms into their bloodstream(process of the ejection from the body). So,whilst it had clearly worked to kill worms,he advised not to use it again on those two. Whilst the other 5 were fine,I have not used since-use Equest instead.
 
And had no probs with Equest btw. Difficult,as I think it's very much individual to the horse but perhaps those a bit more sensitive(the 2 who reacted are also sensitive to any shampoos except mild ones&to fly bites etc and one of them on Pink Powder for sensitive gut) it is supposed to be the safest,is used on pregnant&lactating mares etc. Vet said he would advise it for use on sensitive horses but 'you just never know'. There's always a 'speshul' few,isn't there?! ;)
 
I think it depends how bad the worm burden is before it's given. If they are very wormy to start with then the dead ones can cause serious problems and blockages. My vet said to be careful using it on things that you think have a large burden for thus reason.
 
That's probably the long and the short of it, patterdale.

I guess it depends what you are aiming to treat with it. At this time of the year the encysted bug*ers will have erupted anyway I think, so might as well us any of the other chemicals which treat the adults.

My only experience with panacur equine guard was.. well, you'll all laugh. My horse (12 years ago) was looking ill-thrifty, even though he had been wormed. YO got the crystal lady out (god knows why, it wasn't specifically for my lad) who dangled her crystal over him and pronounced he had redworm and to treat with (something, can't now remember what)... :D YO advised me that she knew of a much better wormer than that one, and so he went on panacur 5 day.

Dunno how the hell a dangly crystal can tell you which worms he had (I have a supply of cynicism for this) but I won't slag her off because fair play he did get better very soon after that! :D
 
I used it recently then did a worm count a few weeks later. It had little effect on the worm burden. Spoke to vet who feels it isn't that effective anymore.
 
Slightly confused by the comments about not using it on horses who have a worm burden, on our vets advice and from reading about this wormer it does have a higher resistance.
This is why it is used in horses when you do not know the worming history,it is not so severe and does not cause a mass exit to encysted worms which in turn can lead to severe colic.

You give it over the 5 day period so although it is not so severe will help to clear the worms gradually, you then worm after with another wormer.

If you give something that is not resistant you can cause a mass exodus by the worms and severe colic especially if the horse has encysted red worms a weak worm ridden horse or pony cannot cope with this and it has to happen in stages.

We give this to all horses we get in before they go on to our pasture over 5 days as instructed by our vet we have never had a problem and I would be very careful of giving a stronger wormer to a horse you suspect may have a worm burden.
 
Funny reading some of the comments on here as I gave a five day dose of panacur as I had a pony with an unknown worming history, the dose ended a week ago last saturday and all this weekend he has been suffering from bouts of mild colic, I did wonder whether the two were linked?
 
Equest pramox is far safer according to a lecture I went to a couple of weeks back. It causes less inflammation. But both panacur and equest are dangerous for a horse with a very poor body score so needs careful vet supervision in those cases.
 
Hello I have held an AMTRA qualification for 4 years (meaning I can sell horse wormers) and I was taught that there are trials showing 100% resistance in gutworms to white wormers (Benzimidazole - Panacur) throughout the UK. I was also told that although Panacur will treat encysted larvae unlike Equest that will kill the larvae in the gutwall, Pancur triggers the emergence of the larvae before killing them. This is only what I was taught but I would much rather use faecal egg counts and a dose of Equest Pramox if needed. Hope this helps.
 
With my friend's horses - one of which that died, she did regular worm counts and thought that her horses had very low worm burdens (she has her own 15 acres and poo picks religiously). However it is thought that she had been doing the counts at the wrong times of year, so that the worms were not active and did not show on the counts.. Therefore the horses did actually have high worm burdens because, due to the worm count readings, they had not been wormed as often.

The theory was, as the worms were killed, they were replaced by ones that had been embedded in the gut wall - this kept happening as the dosage went on, and it left the gut wall with lots of holes and the gut full of dead worms...
 
May I ask you what times of year you should do worm counts? A friend's son did a thesis on it for his vet's exams and said only a couple of periods gave accurate readings, but I can't remember when he said!
 
Confused, mums boy worm count was fine, 3 weeks later we saw more pin worms in mid boy pooh, spoke to my vet who recommended 5 day panacur, but now I'm worried about some of the horrifying stories on here, think I will just to to keep a close eye on both boys

I agree with this absolutely. Its not the Panacur Guard which causes the problem its the worms! Either because the horse has lots and the wormer has done its job ie killed the worms or because some worms are resistant and they dont get killed. Resistance is easy to spot by having a reduction worm count done.
Personally I have been told by my vet that panacur strongid-p are preferable to the more modern ivermectin and moxidecin as both the later have their own set of problems and ivermectin is implacated in EGS sucesptaility and moxidection can be rather harsh and cause problems eg colic because of that. theres lots of threads on here about all this.
You are best advised to speak to your vet TBH.
