Treatment
The ideal method would be prevention by improved sanitation (proper disposal of feces), practicing good hygiene (washing of hands), etc., before any drug regimen is administered.
Ivermectin is the drug of first choice for treatment because of higher tolerance in patients.[14] Thiabendazole was used previously, but, owing to its high prevalence of side-effects (dizziness, vomiting, nausea, malaise) and lower efficacy, it has been superseded by ivermectin and as second-line albendazole. However, these drugs have little effect on the majority of these autoinfective larvae during their migration through the body. Hence, repeated treatments with ivermectin have to be administered to kill adult parasites that develop from the autoinfective larvae.
In the UK, mebendazole and piperazine are currently (2007) preferred.[15]

Strongyloides stercoralis, also known as the threadworm, is the scientific name of a human parasitic roundworm causing the disease of strongyloidiasis.
Strongyloides stercoralis is a nematode that can parasitize humans. The adult parasitic stage lives in tunnels in the mucosa of the small intestine. The genus Strongyloides contains 53 species[1][2] and S. stercoralis is the type species. S. stercoralis has been reported in other mammals, including cats and dogs. However, it seems that the species in dogs is typically not S. stercoralis, but the related species S. canis. Non-human primates are more commonly infected with S. fuelleborni and S. cebus although S. stercoralis has been reported in captive primates. Other species of Strongyloides naturally parasitic in humans, but with restricted distributions, are S. fuelleborni in central Africa and S. kellyi in Papua New Guinea.
In American usage, Strongyloides is usually called threadworm; in British usage, however, threadworm may refer to Enterobius while Strongyloides is called pinworm.[3]
