Since it is spreading and feels warm despite using Allegra (fexofenadine), Permed (permethrin), and Gris-ODT (griseofulvin), it is very important to contact her prescribing doctor or a dermatologist promptly. A spreading, warm rash could suggest that the current treatment needs adjusting, or it could indicate a secondary skin infection or an allergic reaction. In the meantime, applying cool, damp compresses can help soothe the itching and warmth. Please encourage her to avoid hot showers and scratching. A quick medical evaluation is the safest way to ensure she gets the right relief.
