I haven't tried these meds yet, but tried Ivermectin twice on it's own, for ascarids and it didn't seem to have any effect?
Pyrantel Paomate liquid from E-Bay I tried once before anything else, under the assumption by most info sources that it would kill them, it just paralyzed them, and I could feel a few drop off! :(
Maybe some were expelled, but I don't know for sure? Either way, you need a fast acting laxative to flush them out, (although the bottle said "do not use a laxative") so I assume there's a laxative already in it? And maybe it would dilute the action of it, I don't know?
