eprinex versus ivermectin

[Gonda]

I'm very interested in learning what the difference is between eprinex and ivermectin. I've had to look extensively to dig up some definitive information so thought it was worth sharing.

After some extensive searching, I came across this site in my research:
http://www.jefferslivestock.com/eprinex … /cp/17185/ which is where they sell ivomec eprinex pour on for cattle. They also sell ivomec ivermectin pour on for cattle: http://www.jefferspet.com/ivomec-pour-on/p/17186/

If you read the descriptions of the two drugs in terms of how they work, they're pretty much identical, it seems.

Ivomec Eprinex contains Eprinomectin and Ivomec Ivermectin contains ivermectin.

Their mode of action seems to be identical, as is the dosing. It seems Eprinex kills more than the ivermectin does. It says here that eprinex is "the broadest-spectrum parasite control product available. Only EPRINEX

kills 42 species and stages of internal and external parasites, including roundworms, lungworms, grubs, mange mites, horn flies, and biting and sucking lice."

Ivermectin pour on has a 48 day withdrawal period for cattle, while Eprinex has a a zero withdrawal recommendation for cattle. That's quite a significant difference that seems is worth considering for poultry as well, though they're off label use for poultry to begin with.


So, is it safe to say then that Eprinex (versus ivermectin) is the better choice for poultry, for mites/lice/deworming? I thought I should raise this question as it really is not clear what the difference is when I read the various poultry forum postings, and the information seems a bit hard to find.

That's an interesting statement, since albendazole is the only one that kills tapeworms.

I've also read where dawg53 said one of them (Eprinex?) is losing effectiveness due to widespread use and resistance.

After doing my research, I chose to buy Eprinex to treat my poultry lice. It did not work at all. I later found out that feather lice that eat the feathers may not get the medicine needed to kill them. I used a dropper of .5ml to the back of each neck, down deep to the skin. That was just my experience...for what it's worth.

So did you end up trying one or the other? Have any luck? Anyone else have any input?

Eprinex still works on most internal fowl parasites along with mites that suck blood. It has lost much of its zing for the beef industry. The "white wormers" like Valbazen and Safe-Guard, albenzadole and fenbenzadole, are more effective and less toxic to the host. They do require oral dosing though which many try to avoid. Best to start with the -benzadole first followed in 10 days by the -mectin.

Lice are best treated with Permethrin or Seven dust.
