FDA-Approved Indication
- Nystatin topical powder is specifically indicated for cutaneous or mucocutaneous mycotic infections caused by Candida albicans and other susceptible Candida species 1
- The groin area is a common site for candidal skin infections, particularly in obese and diabetic patients 2
Application Protocol
- Clean and dry the affected area thoroughly before each application 2
- Apply nystatin powder to the groin area as directed
- Continue treatment for 7-14 days until the infection has completely resolved 2

Effectiveness Profile
- Topical nystatin is effective against Candida species causing skin infections 2
- Nystatin demonstrates high efficacy with 81.72% of Candida strains showing sensitivity 3
- For vulvovaginal candidiasis (a related condition), nystatin achieved 78.3% mycological cure rates, comparable to fluconazole 4
When Nystatin May Be Particularly Useful
- For Candida glabrata infections: Nystatin showed 64.3% cure rates versus only 12.5% for fluconazole 4
- For fluconazole-resistant Candida: Nystatin successfully treated 5 of 9 patients, while fluconazole failed in all 7 resistant cases 4
- These advantages make nystatin a valuable option when azole resistance is suspected or confirmed 2, 4
When to Consider Alternatives
- For complicated infections or non-response to topical therapy: Systemic antifungals may be required 2
- Topical azoles (clotrimazole, miconazole) can be considered as alternatives for resistant cases 2
- Oral fluconazole may be necessary for more extensive infections that don't respond to topical treatment 2
