Linda, you bring up a very good point.  In cattle, there are times when one simply doesn't give dewormers that kill encysted or migrating phases, because there are potentially so many that the death of them all at once can cause anaphylactic shock and death.  I'm beginning to think that folks had likely best check the local times when bots are migrating, and avoid those times of year for doing the fenbendazole purge as well.  Likely the most dangerous time of year is late fall and early winter--at any rate, it is for cattle with migrating grubs, but the bot life cycle is somewhat similar.  Each locale has its own "cut-off" time for doing cattle because of this.

Subject: RC: Re: Panacur Purge

I did a Panacur purge on my horse late last fall

for the first time in the six years that I have owned him.

The only thing unexpected was that my horse

broke out in welts all over his body beginning

the third day of the purge.  He wasn't a very happy

camper.  The welts disappeared the second day

after the completion of the five day purge.

 

It turns out they actually *do* warn you about

this.  If there are encysted buggies in the muscle

tissue, they emit an irritant toxin as they begin to die

and the horse's body responds with swelling.

The Panacur also caused a number of bots

that were working their way into the jaw to

do a quick exit, resulting in supprating sores

under the jaw.
