Few things cause more parental anxiety than a child with a fever. While fever is actually a healthy immune response, knowing when and how to treat it with medication is essential knowledge for every parent and caregiver. This guide covers everything you need to know about managing children's fevers safely. ## Understanding Fever in Children A fever is generally defined as a temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher. Fever itself is not an illness but a symptom indicating that the body is fighting an infection. In most cases, fever is not dangerous and does not need aggressive treatment. The goal of treating a fever is not necessarily to bring the temperature back to normal but to make the child more comfortable. A child with a fever of 102 degrees who is playing happily may not need medication, while a child with 101 degrees who is miserable and unable to sleep would benefit from treatment. ## When to Treat and When to Call the Doctor For infants under 3 months, any fever of 100.4 degrees or higher requires immediate medical attention. Do not give fever medication without contacting your pediatrician first. For infants 3 to 6 months, call your doctor for fevers of 102 degrees or higher, or if the fever lasts more than one day. For children over 6 months, treat if the child is uncomfortable. Call the doctor if the fever exceeds 104 degrees, lasts more than 3 days, or is accompanied by concerning symptoms. Warning signs that require urgent medical attention include difficulty breathing, severe headache or stiff neck, unusual rash (especially one that does not blanch when pressed), persistent vomiting, extreme lethargy or unresponsiveness, and seizures. ## Acetaminophen (Tylenol) Dosing Acetaminophen can be given to infants as young as 2 months (with pediatrician guidance) and is available as Infants' Tylenol (160 mg/5 mL) and Children's Tylenol (160 mg/5 mL). These now have the same concentration. The dose is 10 to 15 mg per kilogram of body weight, given every 4 to 6 hours as needed, with a maximum of 5 doses in 24 hours. Always dose by weight, not by age, using the provided measuring device. ## Ibuprofen (Motrin/Advil) Dosing Ibuprofen can be given to children 6 months and older. Children's Motrin/Advil (100 mg/5 mL) is the standard formulation. The dose is 5 to 10 mg per kilogram of body weight, given every 6 to 8 hours as needed, with a maximum of 3 doses in 24 hours. Ibuprofen has the advantage of reducing inflammation as well as fever and may provide slightly longer fever reduction. ## Alternating Medications Many pediatricians recommend alternating acetaminophen and ibuprofen for persistent fevers that do not respond well to a single medication. A typical schedule involves giving one medication, then giving the other 3 hours later. For example, give Tylenol at 8 AM, Motrin at 11 AM, Tylenol at 2 PM, and Motrin at 5 PM. This approach takes advantage of the different mechanisms and timing of the two medications to provide more consistent fever control. The critical safety rule is to track each medication separately and never exceed its individual maximum daily dose. ## Critical Safety Rules Never give aspirin to children under 18 (risk of Reye's syndrome). Never give ibuprofen to infants under 6 months. Always use the measuring device that comes with the product, not a kitchen spoon. Check all other medications for acetaminophen content to avoid double dosing. Do not wake a sleeping child to give fever medication unless your doctor specifically advises it. ## When Medication Is Not Needed Not every fever requires medication. If your child has a mild fever but is eating, drinking, playing, and sleeping normally, watchful waiting is perfectly appropriate. Keep the child hydrated, dress them in light clothing, and monitor for any changes. Fever is a natural part of the immune response and may actually help the body fight infection. *This article is for informational purposes only and does not constitute medical advice.
