From the Guidelines

Terbinafine 1% cream should be applied daily for 1 week to treat tinea cruris (jock itch) in individuals 12 years and older, as it has been shown to have a mycological cure rate of approximately 94% 1. When applying terbinafine 1% cream, it is essential to follow proper guidelines to ensure effective treatment and prevent recurrence.

  • Before application, wash and dry the affected area thoroughly to prevent moisture from interfering with the cream's effectiveness.
  • Apply a thin layer of the cream to the affected area and surrounding skin, gently massaging it into the skin until absorbed.
  • Continue treatment for the full prescribed duration of 1 week, even if symptoms improve earlier, to prevent recurrence.
  • To prevent spreading the infection to other body parts, wash hands thoroughly after application and avoid applying the cream to broken skin, mucous membranes, or eyes.
  • For best results, keep the groin area clean and dry, wear loose cotton underwear, and avoid sharing personal items like towels.
  • If symptoms worsen or don't improve after one week of treatment, consult a healthcare provider for further evaluation and guidance, as oral antifungal medications like itraconazole may be necessary for severe cases 1.
