Patients who have ringworm should visit medical professionals and follow their individual instructions for treatment, according to WebMD. Humans and pets should not share medication, because their dosage and ingredient requirements would generally be different, reports Slate.
Doctors may recommend antifungal cream and antifungal pills such as Lamisil, Tinactin or a corticosteroid, explains WebMD. Veterinarians may suggest antifungal pet shampoo and drugs such as Lamasil or griseofulvin, notes VCA Animal Hospitals. Medication for pets often include ingredients that do not undergo safety testing for human consumption, reports Slate. Ringworm is a fungal skin disease that causes red, worm-like rashes, according to Mayo Clinic. Owners and pets may transfer ringworm to each other through contact with the skin or contaminated items.
