I hope Doc comes back on here because children have to be dealth with differently.
If I decided to do the Zymex 11, I would cut it down a little to like maybe 2 or 3 capsules and be sure to give it in between meals so it digests tapeworm and not food. The Zymex 11 will digest other worms like ascaris, too, and other intestinal worms when it is taken in between meals. I think this kid needs help soon, so take it or leave it for the suggestions here. It's all natural, and some adults have drank a quart of Barefoot dewormer at a time with no problems, so maybe the kid needs to stay on the dewormer since the problems persist.
