Pyrantal pamoate has been used effectively against tapeworms for a long
time at double the normal dosing strength but this has been an off-
label usage. Recently, the FDA approved this dosage as effective for
the control of tapeworms. So now there are two FDA approved dewormers
available for use in horses- praziquantel and pyrantel pamoate at
double the standard dosage. Personally, I have used both in my
IR/Cushings boys with no problems. The praziquantel MAY be a problem so
as there is an effective, FDA approved, safe alternative that would
seem to be the prudent alternative to use in an animal when you aren't
sure if they will react.

As a barn manager, I would give you no choice under the circumstances either. Our policy is that every horse come onto this farm and is on our deworming program - period. There are no other options and that is simply our standard of care. Never had one boarder have a problem with it to be honest.

That said, I would certainly be open minded to the *type* of wormer being used on a compromised horse. We don't use Quest on some horses if we feel there's a risk. Instead we will do two Ivermectin dewormings 30-45 days apart.

Worming horses for tapeworm gets ride of them in the body - does not get rid of tapeworms in the environment which is what will reinfest the horses. If the boarders horses has tapeworms, dollars to donuts your horse has tapeworms and you should take this very seriously, in my opinion.

Dr. Kellon advises caution for Praziquantel in uncontrolled IR horses due to studies in other species showing problems with insulin. In controlled IR and Cushing's horses here we've personally had no problems.

I think this is the issue.
