Marine Stings and Scrapes - Home Treatment

Seabather's eruption

  • Do not rub your skin. If larvae are on your skin, rubbing will cause them to sting.
  • Remove your swimsuit as soon as possible. Since larvae can become trapped in the fabric of your suit, it is important to remove a contaminated suit to prevent more stings.
  • If available, rinse in household vinegar (5% acetic acid solution) or rubbing alcohol (40%–70% isopropyl alcohol).
  • Shower with fresh water. Apply soap and vigorously scrub your skin. Do not shower with a contaminated suit on. If larvae are trapped in the fabric of a suit, a freshwater shower will cause the larvae to sting.
  • Take an antihistamine, such as diphenhydramine or chlorpheniramine, or apply 1% hydrocortisone cream cream to help control itching. Note: Do not use the cream on children younger than age 2 unless your doctor tells you to. Do not use in the rectal or vaginal area in children younger than age 12 unless your doctor tells you to. Also, don't give antihistamines to your child unless you've checked with the doctor first.
  • Use an ice pack to help relieve pain.
  • Wash the rash with soap and water daily.
