What Are the Treatments for Sea Lice?

Sea lice actually are not lice at all. They are the microscopic offspring of jellyfish; However, since their effects are similar to those of head or pubic lice, they have gained the nickname of sea lice. Like adult jellyfish, these small larvae have small stingers. When agitated, sea lice can cause an irritating skin rash.

Location

• Sea lice are generally found in warmer waters, especially in the Caribbean and the Gulf of Mexico. The most common culprit is the thimble jellyfish, which can migrate to other areas depending on the water temperature and the sea current. Sea lice are most active between April and August.

Before Treatment

• Before treatment, remove your bathing suit completely and shower to wash away any residual larvae. Any type of application, even fresh water, can cause the jellyfish stingers to activate and continue injecting toxins into your body. Do not wear the suit until after it has been through the washer several times and dried with high heat.

Vinegar

• Dilute a bottle of vinegar with about a gallon of water. Using a soft sponge, gently cleanse the areas that have been affected and are starting to itch. The vinegar should help neutralize any remaining toxins. Once you have cleansed with the vinegar, rinse off in the shower.

Ice

• If you are still feeling uncomfortable, apply an ice pack to the affected area. The cold should help relieve any swelling and dull the pain.

Topical

• To help relieve the itching, apply skin treatments such as calamine or hydrocortisone lotion or cream. After washing the area thoroughly, apply a thin coating to the rash. Continue this process two to three times a day until the itching is gone. Always read the instructions on the treatments to avoid possible side effects.

Medication

• Anti-inflammatory drugs may also help relieve the swelling and pain associated with sea lice stings. However, most such drugs have not been approved for children under the age of 12. Check with your doctor for treatment options for your child if the stings are serious enough to warrant medication.
