The Persistence of Nystatin Use for Dermatophyte Infections
Background:
Despite the limited use of nystatin for tinea infections, physicians may continue to use it.
Methods:
We assessed the National Ambulatory Medical Care Survey for all to determine the extent of topical nystatin use in tinea infections.
Results:
Topical nystatin was used at 4.3% (2.1%, 6.0%) of all tinea infection visits. It was not used at visits with dermatologists and was most common among family medicine physicians (P=.02).
Discussion:
Physicians are continuing to use nystatin for the treatment of tinea infections. Dermatologists have discontinued this treatment regimen, whereas other specialties have an opportunity to further improve their knowledge in this regard. J Drugs Dermatol. 2023;22(12):e49-e50. doi:10.36849/JDD.5606e.
Insights
Physicians still prescribe nystatin for tinea infections, despite its limited effectiveness. This topical antifungal use is more common in family medicine than dermatology, indicating a need for updated clinical knowledge.
Area of Science:
- Dermatology
- Infectious Diseases
- Pharmacology
Background:
- Nystatin, an antifungal medication, is often prescribed for tinea infections.
- The efficacy of nystatin for treating superficial fungal infections like tinea is debated.
- Physicians' prescribing patterns for nystatin in tinea infections warrant investigation.
Discussion:
- Topical nystatin was prescribed in 4.3% of tinea infection visits.
- Dermatologists rarely used nystatin for tinea infections, unlike family medicine physicians.
- A significant difference (P=.02) in nystatin use was observed between medical specialties.
Key Insights:
- Nystatin remains in use for tinea infections despite limited evidence of efficacy.
- Prescribing patterns vary significantly across medical specialties.
- Dermatologists have largely ceased using nystatin for tinea infections.
Outlook:
- Further education is recommended for non-dermatology specialties regarding appropriate tinea treatment.
- Clinical guidelines should emphasize evidence-based therapies for fungal skin infections.
- Future research could explore reasons for continued nystatin use in specific practice settings.
