Risk Factors

Hot, humid conditions can increase your risk of jock itch. Other risk factors include:
  • Perspiring heavily
  • Being obese
  • Wearing tight clothing
  • Wearing dirty clothing, especially underwear or athletic supporters
  • Infrequently changing underwear
  • Infrequent showering
  • Sharing towels or clothing with other people
  • Using public showers or locker rooms
  • Contact sports such as wrestling
  • Having an immune system disorder
Both men and women can be affected. The condition is more common in men, especially those who perspire heavily.


Over-the-counter antifungal creams can usually treat jock itch. Creams or lotions work better on jock itch than sprays. In severe or persistent cases, your doctor may prescribe stronger creams or oral medicine. Use your prescription for the entire time that your doctor recommends. This will help prevent the rash from returning. If your rash does not go away within a month of treatment, call your doctor.

Oral Medications

If the rash doesn't improve with the cream, your doctor may need to prescribe an oral medicine.
Call the doctor if the rash begins to ooze. The rash may be secondarily infected with bacteria. If your doctor confirms this, you may be given an antibiotic.

Lifestyle Changes

These steps can also help to treat jock itch:
  • Dry the infected area before dressing.
  • Avoid sharing clothing and towels with others.
  • Wear loose-fitting clothes that are made out of cotton. Another option is to wear clothes that are designed to wick moisture away from your skin.
