Fungi and yeast (a type of fungus) can be treated with a variety of products, both topical and oral. Griseofulvin is not included in this list because other drugs are less harsh and also effective.
Recommended dosages vary from 30mg/kg to 45mg/kg to 90 mg/kg. Program seems to have a high range of safety. Must be taken with a fatty meal -- perhaps 1cc of flax seed oil for better absorption.
Oral and topical antifungal agent -- used primarily to treat oral or intestinal Candida infections.
Oral Dosage: no dose is listed for guinea pigs in Carpenter's Formulary. However, dosages for other species are listed. Depending on species, dosage varies from 22,000 Units/kg/day to 500,000 IU/kg twice daily. For example, the cat dosage is 100,000Units POq6h.
Nystatin can be used to treat an overgrowth of yeast in the intestinal tract. Droppings that are soft and look pitted can be tested for yeast by a vet. It is not absorbed systemically when taken by mouth. It appears to be safe in pregnant animals. If given in high doses may cause anorexia and diarrhea. Since it is not absorbed, it is not toxic when ingested (toxicity would be very rare) though temporary GI stress can result. It is contraindicated in animals that have shown previous hypersensitivity. Store room temp/in dark/avoid moisture.
As a topical treatment, it is used to treat Candidal (Monilial) skin infections. Nystatin is the principal ingredient in Panalog (other active ingredients: neomycin and triamcinolone).
