Ringworm is a common fungal infection that mostly affects toddlers and school-aged children. The infection is easily spread through physical contact between infected children, animals and surfaces. The main symptom of ringworm is the appearance of dry, itchy, bald patches in the scalp that may appear in the shape of a “ring”. The patches may also be painful or sensitive to touch.
The usual treatment for ringworm includes anti-fungal medications which are taken by mouth. Two commonly prescribed medications are griseofulvin (Gris-PEG) and terbinafine (Lamisil oral tablets). They both work to stop fungal growth and may take up to six weeks to eliminate the infection. In addition to anti-fungals, washing the scalp with an over-thecounter, medicated shampoo such as Selsun Blue (selenium sulfide) helps clear the fungus and prevents the spread of the infection to other body parts.
