What topical antifungal (antifungal medication), available only by prescription, is suitable for use in infants aged 6 months?

From the Guidelines

Nystatin is the prescription-only topical antifungal that can be used in infants as young as 6 months old. This medication is available in various forms, including cream, ointment, or powder, and is primarily used to treat candidiasis (yeast infections) on the skin 1. For infants, the typical application involves a thin layer to affected areas 2-3 times daily until the infection clears, usually continuing for 48 hours after symptoms resolve.

Key Considerations

• Ensure the area is clean and dry before application
• Use only the amount prescribed
• Wash hands before and after application
• Nystatin works by binding to sterols in the fungal cell membrane, creating pores that lead to cell death
• It's particularly effective against Candida species and has a good safety profile in infants due to minimal systemic absorption when applied topically, making it suitable for young patients under medical supervision through prescription.

Application and Safety

• The medication should be applied as directed by a healthcare provider
• Monitoring for any signs of adverse reactions or interactions is crucial, although rare in topical use
• Nystatin's effectiveness and safety for infants as young as 6 months old make it a viable option for treating fungal infections in this age group, as supported by guidelines such as those from 1.

From the Research

Topical Anti-Fungal Medications

• The following topical anti-fungal medications are available by prescription:
  • Clotrimazole
  • Nystatin
  • Miconazole 2, 3, 4
• These medications can be used to treat various fungal infections, including cutaneous candidiasis 4

Age Restrictions

• There is evidence to suggest that some of these medications can be used in infants as young as 6 months old, but the specific medication and dosage would depend on the individual case and the prescribing doctor's advice 5, 4
• Ketoconazole has been used to treat severe Candida infections in newborn infants and babies, but it requires rigorous controls of liver function due to the risk of hepatotoxic reactions 5

Prescription Requirements

• All of the mentioned topical anti-fungal medications require a prescription from a doctor 2, 3, 4
• The choice of medication and treatment plan would depend on the individual case and the prescribing doctor's advice, taking into account factors such as the type and severity of the infection, as well as the patient's age and medical history 5, 6, 4
