I recently discovered that worms are now showing resistance to Panacur and was wondering if anyone uses

Oxibendazole.

I have itchy butted horses that zimecterin gold 6 weeks ago doesn't seem to be helping.

Can you give the oxibendazole in a 5 day double dose like panacur?

Sorry I have no information to answer your actual question but are you sure the horse is itchy because of worms? There are a number of other things that can lead a horse to itching. There is a thread on here from this morning that describes some of the causes.

Yep I checked that thread. Alot of good ideas there. Unfortunately I've checked all those suggestions. And I will bath them all with Lime Sulfur this weekend.

Tail rubbing is caused from pinworms, you need to use pyrantel pamoate (Strongid brand name) to kill the pinworms, I don't think that fenbendazole, ivermectin (in Zimectrin Gold) or oxibendazole is as effective on pinworms.

The double dose of fenbendazole for 5 days is to kill encycsted strongyles and will not have anything to do with tail rubbing.

Sometimes insect bites or allergies cause it too. Have you talked with your vet about it?

The Ivermectin packaging says it gets rid of Pinworms (adults and fourth-stage larvae). Is this not the case?

Jill thats what my vet told me. I also talked with Dr. Barr at Rood and Riddle a large vet clinic in Kentucky and she said horses are now showing resistance to certain types of wormers. So I am looking for a wormer that I have never used on my horses before. And this one is the only one. I was hoping someone had used it and it cured the itchy butt. Panacur double dose didn't, zimecterin gold or zimectrin didn't and neither did the pamoate. I'm going to try it this weekend I'll post my results.
