From the FDA Drug Label
DOSAGE AND ADMINISTRATION ... Pediatric patients (older than 2 years): A dosage of 10 mg/kg daily is usually adequate The FDA drug label does not answer the question.
From the Research
For a 3-month-old with ringworm, the most effective treatment is likely to be a topical antifungal cream, but due to the age of the patient, it's crucial to consult a pediatrician before starting any treatment. The pediatrician will likely recommend a topical antifungal cream specifically safe for infants, such as clotrimazole 1% or miconazole 2% 1.
Key Considerations
- Apply a thin layer to the affected area twice daily for 2-3 weeks, continuing for at least one week after the rash disappears.
- Keep the area clean and dry, washing with mild soap and water before each application.
- Avoid covering the treated area with tight clothing or bandages.
- During treatment, wash your hands thoroughly before and after touching the affected area, and don't share towels, clothing, or bedding to prevent spread.
- Ringworm is a fungal infection, not caused by worms, and infants are particularly susceptible due to their developing immune systems.
Oral Medication
If the infection worsens, spreads, or doesn't improve after a week of treatment, return to the doctor as oral medication might be needed, with itraconazole being the most effective option according to recent studies 2.
Treatment Duration
The treatment duration may vary depending on the severity of the infection and the response to treatment, but generally, treatment should continue for at least one week after clinical clearing of infection 3.
Important Notes
It's essential to note that while there are various treatment options available, the most recent and highest quality study 2 suggests that itraconazole is the most effective oral antifungal drug, but this should only be considered under the guidance of a pediatrician for a 3-month-old infant.
