Treatment

The allergic reaction to penetrating cercariae is self-limiting; signs and symptoms usually will resolve within 1-2 weeks. Minimal symptomatic treatment and good hygiene to prevent itching and secondary infections are usually sufficient treatment for most cases of cercarial dermatitis.

Treatment of cercarial dermatitis has not been evaluated in clinical trials. Systemic antihistamines or topical antihistamines or corticosteroids can be used to reduce symptoms. Topical antiseptics or antibiotics as well as systemic antibiotics may be needed in the case of secondary infection.
