Which patient scenario could be safely managed with over‑the‑counter antifungal treatment in a community pharmacy?

• A. A 35-year-old man with burning around the head of the penis
• B. A 35-year-old patient on carbimazole with an in-range TSH
• C. A 20-year-old woman who is pregnant
• D. A 60-year-old with diabetes and neuropathy

Answer: (A)

OTC topical antifungals are appropriate for uncomplicated, superficial fungal infections in adults when there are no red flags. The healthy man with burning around the head of the penis could have candidal balanitis, a surface fungal infection, which is typically treatable with a short course of a topical azole in a community pharmacy. The advice would be to use the antifungal as directed, keep the area clean and dry, avoid sexual contact until resolved, and seek care if symptoms persist beyond a week, worsen, or if any discharge, ulcers, fever, or other concerning signs develop.

The other scenarios raise safety or appropriateness concerns. Pregnancy can complicate treatment choices, and while some topical azoles are generally safer, professional guidance is preferred. Diabetes with neuropathy increases the risk of atypical or more serious infections and may require medical evaluation rather than self-care. A patient on carbimazole may have drug interaction considerations or other safety issues that make self-treatment less appropriate without clinician input.
