Treatment
Pet animals
Treatment requires both systemic oral treatment with most of the same drugs used in humans—terbinafine, fluconazole, or itraconazole—as well as a topical "dip" therapy.Because of the usually longer hair shafts in pets compared to those of humans, the area of infection and possibly all of the longer hair of the pet must be clipped to decrease the load of fungal spores clinging to the pets hair shafts. However, close shaving is usually not done because nicking the skin facilitates further skin infection. Twice-weekly bathing of the pet with diluted lime sulfur dip solution is effective in eradicating fungal spores. This must continue for 3 to 8 weeks.Washing of household hard surfaces with 1:10 household sodium hypochlorite bleach solution is effective in killing spores, but it is too irritating to be used directly on hair and skin. Pet hair must be rigorously removed from all household surfaces, and then the vacuum cleaner bag, and perhaps even the vacuum cleaner itself, discarded when this has been done repeatedly. Removal of all hair is important, since spores may survive 12 months or even as long as two years on hair clinging to surfaces. Cattle
In bovines, an infestation is difficult to cure, as systemic treatment is uneconomical. Local treatment with iodine compounds is time-consuming, as it needs scraping of crusty lesions. Moreover, it must be carefully conducted using gloves, lest the worker become infested.
Kaopectate is an orally taken medication from  Arcadia Consumer Healthcare for the treatment of mild diarrhea. It is also sometimes used to treat indigestion, nausea, and stomach ulcers. The active ingredients have varied over time, and are different between the United States and Canada. The original active ingredients were kaolinite and pectin. In the US, the active ingredient is now bismuth subsalicylate (the same as in Pepto-Bismol). In Switzerland, attapulgite is used. Ingredients
The active ingredient in Kaopectate has changed since its original creation. Originally, kaolinite was used as the adsorbent and pectin as the emollient. Attapulgite (a type of absorbent clay) replaced the kaolinite in the 1980s, but was banned by the U.S. Food and Drug Administration in a ruling made in April 2003. As a consequence, since 2004, bismuth subsalicylate has been used as the active ingredient in U.S. marketed products. In Canada, McNeil Consumer Healthcare continues to market Kaopectate using attapulgite as the active ingredient. However, Kaopectate was recalled in July 2021 in Canada because it may contain arsenic and lead beyond acceptable limits.As of 2020, the US rights to Kaopectate are owned by Arcadia Consumer Healthcare (formerly Kramer Laboratories). Other animals
The U.S. Food and Drug Administration (FDA) does not have a clear stance on the administration of Kaopectate products on animals such as dogs and cats suffering from diarrhea. However, the Journal of the American Veterinary Medical Association Journal news article noted in 2003 that the new salicylate formulation might be harmful to cats.
