I agree that is is a dangerous assumption to presume that something good for animals is good for humans too, but in this case, pyrantel pamoate is being used for humans ( a product called combantrin ) for pinworms.
Actually, I'm not referring to the substance but to the formulation. The danger I mention lies in the faulty logic:
IF A is safe for MOST B, THEN it should be fine for C.
Notice the word "MOST", the construct "it should be fine" with a strong outline on the word "should", and the logical proposition that MOST B should be quite similar to C. This logic would imply great approximation between "MOST B" and C. Dangerous logic, specially in terms of health; my thought.
Given then that it is probably safe for humans to take (though I would n't really want to head to the local feed supplier to get my dosage as suggested in the article that started all of this!) I would like to know how effective the product is against all the parasites discussed on this forum....has anyone else had experience of using pyrantel pamoate? I 'd love to hear more...
There's data on Pyrantel Pamoate spread all over the place. Here's a really quick search:
How Well It Works
Pyrantel pamoate gets rid of pinworm infections more than 90% of the time.1 However, reinfection with pinworms is very common.

However, I agree as well that many tests should be made to see how it kills different species EFFECTIVELY, if they're not available already; nevertheless, I'm not willing to become a test subject myself. I have little information on the substance.
