Medications Medications that are used to kill roundworms are called ascaricides. Those recommended by the World Health Organization for<unk>  are: albendazole, mebendazole, levamisole and pyrantel pamoate. Single‐dose of albendazole, mebendazole, and ivermectin are effective against<unk> . They are effective at removing parasites and eggs from the intestines. Other effective agents include tribendimidine and nitazoxanide. Pyrantel pamoate may induce intestinal obstruction in a heavy worm load. Albendazole is contraindicated during pregnancy and children under two years of age. Thiabendazole may cause migration of the worm into the esophagus, so it is usually combined with piperazine. Piperazine is a flaccid paralyzing agent that blocks the response of Ascaris muscle to acetylcholine, which immobilizes the worm. It prevents migration when treatment is accomplished with weak drugs such as thiabendazole. If used by itself, it causes the worm to be passed out in the feces and may be used when worms have caused blockage of the intestine or the biliary duct. Corticosteroids can treat some of the symptoms, such as inflammation. Other medications * Hexylresorcinol effective in single dose. During the 1940s a crystoid form of this compound was the treatment of choice; patients were instructed not to chew the crystoids in order to prevent burns to the mucous membranes. A saline cathartic would be administered several hours later. * Santonin, more toxic than hexylresorcinol and often only partly effective. * Oil of chenopodium, more toxic than hexylresorcinol Surgery In some cases with severe infestation the worms may cause bowel obstruction, requiring emergency surgery. The bowel obstruction may be due to all the worms or twisting of the bowel. During the surgery the worms may be manually removed.
