Home Care Advice for Ringworm of the Body

1. Antifungal Cream
   • Use Micatin or Lotrimin cream (no prescription needed) 2 times per day.
   • Apply it to the rash and 1 inch beyond its borders
   • Continue the cream for at least 7 days after the rash is cleared
2. Contagiousness: 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. Your child doesn’t have to miss any day care or school for ringworm.
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 or develops any of the “Call Your Doctor” symptoms
