I my self would try to stay away from many of the commercially available anti parasitic medications that are out there.
From my experience as a health practitioner, one has to be very careful about maintaining the viability of the intestinal gut flora. Very few people realize that over 80% of the body's immuns system is found in the gut, and is called Gut Associated Lymphatic tissue, or called GALT for short.
I have read the guidelines within this forum, and respect them, so will only suggest in passing that a product that I have personally uses to rid myself of a bad case of tapeworms. Its called Miracle-Mineral-Supplement , and can be sourced at http://www.mmshealthy4life.com
Its powerful stuff...
I once used a pharmaceutical parasite killer, and it almost did the same to me as well!
