Ridecamp: Re: [RC] [RC] equine tape worms (ugh!)

Double Strongid or Triple Strongid is effective and safe
in treating tape worms.  Irregardless, my most excellent
vet back in CA recommended I worm with double strongid once 
a year.  I read triple strongid in Equus a couple years 
ago.  Equus reported something like 95% kill rate for
double strongid and 100% kill rate for triple.  That's
2x or 3x normal dose for your horse's weight in one dosage.
I believe that Equus issue also had an article linking tape
worms to colic.  I don't know if the 95% kill rate means
it kills 95% of the tape worms in the horse, or if it means 
it kills 100% of the tape worms in 95% of the horses...

With the safety margin on strongid being something over
100x normal dose, this is infact very safe.  I don't know
if daily strongid has been shown to be effective against
tapes, but I would imagine not as you need to get the
concentration up in a single pass.

My worming regime looks something like:
ivermectin
double strongid  (for tapes)
ivermectin
ivermectin
pancur purge  (for encysted strongyles)
ivermectin

An interesting note, a friend of mine got an ivermectin
injection worming for her horse from her vet.  The horse
developed circular sores from thread worms migrating to
the surface and then dying.  It was obnoxious and she
didn't ride when the sores were the worst, but what's more 
obnoxious?  Having sores for a while, or knowing your horse 
has threadworms that the paste wormers haven't killed?  She
worms religiously on about the same schedule as I do so
the worming schedule wasn't the issue, just getting the
concentration up high enough I guess.

Pancur, Strongid, and Ivermectin are all very safe wormers.
I'm not comfortable yet with moxidectin personally.  It 
has a much narrower safety window. I don't use it in my horses and I don't use it in the new heartworm injection in 
my dog.  Accidently overdose a dog with ivermectin, and 
they have neurological problems and then they recover.  Overdose a dog with moxidectin and they die. 

Yup, we adopted a cattle dog.  What a great breed for around 
these here parts...
