High Fever First Aid – What NOT to do

When dealing with high fever first aid, certain actions can make the situation worse. Avoid these common mistakes to keep yourself or others safe.

Do NOT give aspirin to children or teens

Avoid giving aspirin to anyone under 18 years old. It can cause serious complications like Reye’s syndrome, which affects the liver and brain.

Do NOT overdress or overbundle

Covering someone with too many clothes or heavy blankets can raise body temperature further. Use light clothing and breathable covers instead.

Do not try to make someone drink if they are vomiting, drowsy, or unconscious. This can cause choking or aspiration. Instead, seek medical help immediately.

Avoid cold baths, ice packs, or alcohol rubs to lower fever. These methods can cause shivering, which raises body temperature and may be harmful.

When to call 911 or seek urgent care

• If the person has difficulty breathing, persistent vomiting, seizures, or severe headache
• If the fever lasts more than 3 days or is above 40°C (104°F)

• If there is confusion, difficulty waking, or neck stiffness

In these cases, call 911 or go to the nearest emergency department without delay. Prompt medical attention can prevent serious complications.
