First Aid for STINGING LIMU (SEAWEED) STINGS

For mild to moderate cases of skin rash, remove the swimming suit immediately, and wash skin vigorously with soap and water. Wash the suit too. Although unproven, cool compresses or rubbing alcohol may help relieve the pain. For persistent itching or skin rash, try percent hydrocortisone ointment four times a day, and one or two 25 milligram diphenhydramine (Benadryl) tablets every 6 hours. These drugs are sold without prescription. Diphenhydramine may cause drowsiness. Don't drive, swim, or surf after taking this medication. Irrigate exposed eyes with tap water for at least 15 minutes.
 

For severe discomfort, blistering not responding to first aid treatment, eye stings, or any signs of infection (redness, swelling, pus), see a doctor.
 

Victims who have accidentally eaten this limu should suck on ice to relieve pain while going to an emergency room.
 

Any difficulty breathing signals an allergic reaction, always a medical emergency.
