Home Remedies vs. Medical Treatment: When to Seek Help

Home Treatment (Low-Cost Option) – Under $20

Most mild jellyfish stings can be treated at home using:

• Over-the-Counter Pain Relievers – Ibuprofen or acetaminophen ($5 – $15).

💡 Best for: Mild stings causing redness, swelling, or discomfort without severe pain or breathing issues.

Medical Treatment (Higher Cost) – $100 – $10,000+

Seek medical attention if you experience:

• Severe pain that doesn’t improve
• Difficulty breathing or chest pain
• Nausea, vomiting, or dizziness
• Signs of infection (red streaks, pus, fever)
• A sting from a dangerous jellyfish (Box Jellyfish, Irukandji, Portuguese Man-of-War, Lion’s Mane, etc.)

💡 Best for: Moderate to severe stings requiring prescription pain relief, antibiotics, IV fluids, or antivenom.
