What is a Fever?

A fever is a temporary increase in body temperature, often in response to an infection. In children, a rectal or temporal temperature of 100.4°F (38°C) or higher is clinically defined as a fever.

Choosing the Right Medication: Ibuprofen vs. Acetaminophen

Parents often face a choice between two common over-the-counter (OTC) antipyretics:

  • Ibuprofen (e.g. Children's Motrin): An NSAID that reduces both pain and inflammation. It is indicated for children 2 years and older. Dosages should be spaced 6-8 hours apart and must be administered with food to avoid gastric irritation.
  • Acetaminophen (e.g. Tylenol): A pain reliever and fever reducer that is safer on empty stomachs. It can be given every 4-6 hours but lacks anti-inflammatory properties.

Key Pediatric Safety Warning

Never administer adult formulations or exceed recommended weight-based dosages. Always use the syringe or dosing cup provided in the packaging to ensure accurate measurement.
