Jock Itch (Tinea Cruris): Treatment Timeline & Escalation Criteria

Tinea cruris typically resolves in 2–4 weeks with topical antifungals (terbinafine, clotrimazole, ketoconazole) BID + hygiene (dry, loose cotton).

See a doctor if:

• No improvement at 2 weeks
• Spread beyond inguinal folds (buttocks, abdomen)
• Immunocompromised, diabetic
• Severe inflammation, pustules, fever

Oral antifungals (terbinafine, fluconazole) for extensive/refractory cases. Rule out erythrasma, psoriasis, inverse psoriasis, candidiasis.
