HOME CARE ADVICE FOR RINGWORM

  1. Antifungal Cream:

    • Use Lamisil, Micatin or Lotrimin cream (no prescription needed) 2 times per day.

    • Apply it to the rash and 1 inch (2.5 cm) beyond its borders.

    • Continue the cream for at least 7 days after the rash is cleared.

  2. Contagiousness:

    • Your child doesn't have to miss any child care or school for ringworm.

    • Ringworm of the skin is mildly contagious. It requires direct skin-to-skin contact.

    • The type acquired from pets is not transmitted from human to human, only from animal to human.

    • After 48 hours of treatment, ringworm is not contagious at all.

    • Wrestlers, however, should avoid all wrestling until evaluated by your child's doctor.

  3. Expected Course: It clears completely in 3 to 4 weeks. For any recurrences, suspect the household puppy or kitten and take it to the vet for diagnosis and treatment.

  4. Call Your Doctor If:

    • Rash continues to spread after 1 week on treatment

    • Rash is not cleared by 4 weeks

    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
