Jock Itch

Teen Version

What is jock itch?

Jock itch is a fungus that causes a pink, scaly, itchy rash on the inner thighs, groin, and scrotum. (Note: The rash is not on the penis.) Jock itch is also called ringworm of the crotch or tinea cruris. Usually, only males get jock itch.

How can I take care of myself?

  • Antifungal medicine

    Buy Tinactin, Micatin, or Lotrimin powder or spray (nonprescription) at your drugstore. Twice a day put the powder or spray on the rash and at least 1 inch beyond the borders of the rash. Make sure you get the medicine in all the creases.

    Continue using the medicine for several weeks, or for at least 7 days after the rash seems to have gone away.

  • Dryness

    Jock itch will heal much more quickly if the groin area is kept dry. You should wear loosely fitting cotton shorts. Wash shorts and athletic supporters after each use. Wash the rash area once a day with plain water and dry it carefully. Do not use soap on the rash.

  • Scratching

    Scratching will delay the cure, so avoid scratching the area.

  • Contagiousness

    Jock itch is not very contagious. The fungus won't grow on dry, normal skin. You may continue to take gym and play sports. Wash clothes after each use. Storing clothes in a locker or gym bag lets the fungus grow on the clothes.

When should I call my health care provider?

Call during office hours if:

  • There is no improvement in 1 week.
  • The rash is not completely cured in 1 month.
  • You have other questions or concerns.
