Ok. Shark is on top of these things and i rate his advice as excellent and best anywhere.
However, IF this is a Cestoda flat worm (platyhelminths and tapeworms), I cannot fathom NOT using praziquantel at least as part of the treatment - Different sources offer different quality levels of prazi - choosing is somewhat like throwing a dart blindfolded, but assuming truly pure, prazi should still at least be considered as a go-to med for Cestoda. You might explore different source of prazi if having issues. Herx response might also be in play - this could be a sign of the prazi working. See articles on this.
Note mixing (vigerously shaking in small container)prazi powder with a little 80 proof vodka, breaks down powder (prazi is non-soluble in water), and perhaps adding a little flavored water drink for taste reduces greatly the ghastly taste. Absorption rate is reported improved by others which is the real reason to consider this option.
Opinions and recent studies indicate a wide variation of effectiveness on prazi treatment of trematode flukes - so I got that. Prazi has for me been consistently a most effective "part" of treatment. Flukes are tough - staying the coursr of effective treatment critical
