A jellyfish sting is one of the most common summer problems on Spanish beaches. Most stings are mild and settle with simple first aid. Here is what to do, and what not to do.
Quick Answer
| Question | Answer |
|---|---|
| What do I rinse it with? | Seawater, never fresh water. |
| Ice? | Yes, wrapped in a cloth or bag, for about 15 minutes. |
| Vinegar? | Not unless the lifeguard tells you to: it can worsen some stings. |
| Rub it with sand or a towel? | No. |
| When is it an emergency? | Breathing difficulty, chest pain, a whole-body reaction, or a sting near the eye. |
Jellyfish Sting Treatment, Step by Step
- Get out of the water and tell the lifeguard. Many Spanish beaches have a first-aid post.
- Rinse with seawater. Fresh water can release more venom.
- Remove any tentacles with tweezers or gloves, never bare hands.
- Apply cold using ice wrapped in a cloth, for about 15 minutes.
- Ease the pain and itch with paracetamol or ibuprofen if suitable for you. A pharmacist can suggest a cream or an antihistamine.
- Do not rub or scratch.
When to Call 112 or Go to Urgencias
- Difficulty breathing, a hoarse voice, or swelling of the face or throat.
- Chest pain, severe dizziness or fainting.
- A very large sting area, especially in a child.
- A sting in or near the eye.
- A Portuguese man o' war (a blue jellyfish with a floating sail): go to first aid even if symptoms seem mild.
In the Following Days
If the area becomes increasingly red, hot or produces pus, or you develop a fever, it may be infected and a doctor should check it.
Frequently Asked Questions
Does urine help?
No. It is a myth and does not help.
How long does the mark last?
The pain usually eases within hours. The mark can last days or weeks.
Sting not settling, or worried it is infected? Book a video consultation with an online doctor in Spain for urgent, non-emergency care. In an emergency, call 112.
