What is the treatment for swimmer itch?

From the Guidelines

Treatment for swimmer's itch primarily focuses on relieving symptoms while the rash heals naturally within 1-2 weeks. The condition occurs when microscopic parasites from waterfowl penetrate human skin but cannot complete their life cycle, causing an allergic reaction that manifests as an itchy rash 1. Some key points to consider in the treatment of swimmer's itch include:

• Apply cool compresses to the affected areas for 20-30 minutes several times daily to reduce inflammation and itching
• Over-the-counter antihistamines like diphenhydramine (Benadryl) 25-50mg every 4-6 hours or cetirizine (Zyrtec) 10mg daily can help control itching
• Topical treatments such as calamine lotion, hydrocortisone cream (0.5-1%) applied 2-3 times daily, or colloidal oatmeal baths can provide additional relief
• Avoid scratching to prevent secondary infection
• If the rash is severe or becomes infected (showing increased redness, warmth, swelling, or pus), seek medical attention as prescription-strength corticosteroids or antibiotics may be necessary
• To prevent future episodes, dry off thoroughly after swimming in lakes or ponds, shower immediately after water exposure, and avoid swimming in areas known to have swimmer's itch. It's also worth noting that while there are various other conditions and treatments discussed in the provided evidence, such as the management of congenital ichthyoses 1 and infectious diseases associated with organized sports and outbreak control 1, these are not directly relevant to the treatment of swimmer's itch. Similarly, the treatment of cholestasis of pregnancy 1 and eosinophilia in returning travelers and migrants from the tropics 1 are not directly applicable to the treatment of swimmer's itch. Therefore, the most appropriate course of action is to focus on relieving symptoms and preventing secondary infection, as outlined above.

From the Research

Prevention and Risk Factors

• The effectiveness of various preventive measures, such as protective sun cream or patting the skin dry, is controversial 3.
• The use of molluscicides is definitely contraindicated due to the inoffensive nature of this dermatitis 3.
• High temperatures and sunshine increase the risk of encountering the parasite and becoming infected 5, 6.
• A wide variety of often interacting biotic and abiotic factors, as well as personal behavior, have an effect on the likelihood and severity of a human infection 7.
