pyrantel pamoate is pretty cheap and safe over here in the U.S. on amazon and so is fenbendazole - can get each without prescription. albendazole is little more expensive because its min 500 ml bottle here, so about $50, praziquantel cost abt $50 for 50 grams or so.
also, if raw grass-fed milk is reasonable price over there its possible that your body may tolerate it. and if you can get raw colostrum one fellow on here said he cured his digestive problems by drinking one gallon of it in one day. it might work like a nuke bomb on candida and bad bacteria, not sure about parasites though.
