Understanding Fever in Children
First and foremost: What is a fever? A fever in a child is usually a temperature of 100.4°F (38°C) or higher and is the body’s natural reaction to infection. While usually harmless and part of the immune response, a child’s fever can still cause concern for parents. The goal of treatment is often comfort, not necessarily getting your child’s temperature “back to normal.” Knowing when and how to treat a fever can be difficult and depends on several factors, including the severity of the fever, the level of discomfort your child is experiencing, and your child’s response to certain medicines.
"What medicines are recommended?"
For most children 6 months and older, the two most commonly used medicines to relieve fever-related discomfort and pain are:
- Acetaminophen (e.g., Children’s Tylenol)
- Ibuprofen (e.g., Children’s Motrin or Children’s Advil)
Ibuprofen is generally not recommended for babies younger than 6 months unless a healthcare professional has given you specific instructions to use it.
Both types of medications:
- Are safe when used as directed.
- Reduce fever and relieve pain.
- Should be dosed based on your child’s weight, not age (link out to dosing guidelines).
- Should only be administered with the dosing device (i.e., cup or syringe) provided with your medicine.
For most children over the age of 6 months, starting with one medicine - either acetaminophen (Children’s Tylenol) or ibuprofen (Children’s Motrin or Children’s Advil) - is an appropriate first step to reduce fever and discomfort.
For some children, a healthcare professional may recommend using acetaminophen and ibuprofen at different times if discomfort persists or returns before the next dose of the first medicine is due. This is not routinely needed and should not be used simply to lower a temperature number.
Alternating medicines can be confusing and can increase the risk of dosing errors or accidental overdose. Do not alternate acetaminophen and ibuprofen unless your child’s healthcare professional gives you a specific plan. If they recommend it, use a written schedule that records the medicine, dose, and exact time each dose is given.
There is research that suggests that:
- using both medicines at different times may lower temperature more than using one medicine alone over the next several hours.
- some children experience improved comfort and better sleep.
Alternating fever medicines does not treat the infection or shorten the illness.
"What do pediatric health organizations recommend?"
Many major pediatric and medical organizations agree on two key points when it comes to treating fever in children:
- The main goal of fever treatment is comfort, not normalizing temperature.
Fever by itself is often not harmful in most children. Medicines should be used to help a child feel better, stay hydrated, and rest, not just to lower the number on the thermometer.
- Using one medicine is usually preferred.
The American Academy of Pediatrics (AAP) states that although alternating or combining acetaminophen and ibuprofen can lower fever more effectively, it may also raise the risk of incorrect dosing. Therefore, regularly using both medications together is not usually advised unless directed by a healthcare provider.
The AAP and Other Pediatric Experts emphasize that:
- Families who alternate medicines should do so only with clear instructions from their child’s physician and a written dosing schedule.
- Simple regimens reduce errors and are safer for most families.
- Always consult with your child’s pediatrician with questions.
Important Update: Acetaminophen
Takeaways for Parents:
- It is safe and effective to use either acetaminophen or ibuprofen alone for most children.
- Alternating may be considered in certain situations to improve comfort or reduce stubborn fevers, if recommended by your child’s healthcare provider.
- Careful dosing, documentation, and supervision are essential when more than one medicine is used.
When Alternating May Be Considered by a HealthcareProfessional
Your child’s healthcare provider may recommend alternating if:
- your child remains very uncomfortable after receiving one medicine correctly.
- discomfort returns before the next dose of the first medicine is due.
- single therapy has not provided enough relief.
In these situations, alternating therapies may help – but it must be done carefully to prevent dosing errors or accidental overdoses.
If your child is vomiting, drinking poorly, urinating much less than usual, or has other signs of dehydration, contact a healthcare professional. Ask before giving ibuprofen.
A NOTE ABOUT DYE-FREE PRODUCTS: Dye-free medications and supplements are a great option for individuals who prefer or require products without dyes, such as those with allergies, sensitivities, or personal preferences. Importantly, both dye-containing and dye-free options are held to the same rigorous safety and quality standards. If you’re unsure which is right for you or your family, talk to your pharmacist or healthcare provider. They can help you choose the option that best suits your needs.
"How do I alternate my child's fever medications safely?"
If your child’s physician recommends alternating acetaminophen and ibuprofen:
- Write everything down. Record the medicine’s name, strength or concentration, dose in mL, and the exact time it was given.
- Follow correct intervals between medication doses.
- Acetaminophen may only be given as directed on the package label or by your child’s healthcare professional. For children under 12, acetaminophen may be given every 4 hours while symptoms last, with no more than 5 doses in 24 hours. - Dose by weight. Use your child’s weight in pounds (lbs) or kilograms (kg) to calculate correct dosing.
- Only use single active ingredient medicines (e.g., Children’s Tylenol, Children’s Advil). Do not use multi-symptom medicine products. They can contain the same active ingredients, potentially resulting in an accidental overdose.
- Stop treatment once your child is comfortable.
Remember to treat your child's discomfort, not necessarily the number on the thermometer.
When You Should Call Your Child’s Pediatrician
Contact your healthcare professional if:
- your child is younger than six (6) months of age.
- a fever lasts more than three (3) days (>72 hours).
- a fever is 104°F (40°C) or higher.
- your child is vomiting, dehydrated, or lethargic.
- any underlying medical conditions are present.
- you are unsure which medicine to use, how much to give, or when the next dose is due.

Safe Use Tips & Takeaways
Heart Health Takeaways
- A fever is generally considered to be a temperature of 100.4°F (38.0°C) or higher.
- Temperature in infants can be most accurately measured using a digital rectal thermometer.
- Talk to your doctor before giving a pain reliever or fever reducer containing ibuprofen if your baby is younger than 6 months (ibuprofen is generally notrecommended for children < 6 months).
- Talk to your doctor before giving acetaminophen to a child younger than 2 years to obtain the proper dosing instructions - acetaminophen / ibuprofen.
- Before giving your child any medicines, make sure you know your child’s weight. Dosing is based on weight, not age. Be sure to always double check if the drug facts label may list child weight in kilograms or pounds.
- Make sure to read the package label very carefully for proper dosing.
- Always use the measuring device (i.e., cup or syringe) that comes with the medicine. Do not mix and match dosing devices.
- Don’t give aspirin to anyone under 12 years of age unless instructed by your doctor.
- Do not give sponge baths or attempt to reduce your child’s fever with cool or cold water. This can cause shivering and result in an increased body temperature.
