how to treat swimmers itch

Swimmer’s itch usually gets better on its own, but you can reduce the itching with cool compresses, calamine or 1% hydrocortisone cream, and an oral antihistamine like loratadine or diphenhydramine. Avoid scratching, and watch for signs of infection; if the rash is severe, lasts more than about 1–2 weeks, or you get fever or pus, get medical care.

What helps at home

• Put a cool, wet cloth on the rash for 20–30 minutes at a time.

• Apply calamine lotion or an anti-itch cream.

• Use 1% hydrocortisone cream as directed on the package.

• Take an antihistamine for itch relief if appropriate for you.

• Try an oatmeal bath or a baking soda paste if the skin is very irritated.

• Keep nails short and avoid scratching to lower the chance of infection.

When to get help

Seek medical advice if the rash is getting worse, becomes red or pus-filled, or you have a fever. A clinician may recommend stronger prescription creams if the itch is severe.

Prevention next time

Rinse and dry off right after swimming, and avoid waters known for swimmer’s itch outbreaks. It’s often linked to freshwater lakes, especially near shorelines or weed growth.

Quick note

Swimmer’s itch is uncomfortable but usually temporary and not contagious.
