  2. Always use the measuring device that comes with the medicine.
  3. The proper dosage is based on weight, not age.
  4. Never give acetaminophen to a child who’s taking other medicines unless directed by a doctor. Other medicines may also contain acetaminophen, creating a dangerous overdose.
  5. Please remember to keep all medications out of your child’s reach at all times.

Frequently Asked Questions About Pediatric Medication

Both are effective for reducing fever and relieving pain in children. Acetaminophen (Tylenol) can be used in babies as young as 2 months (with physician approval for under 3 months). Ibuprofen (Motrin, Advil) should not be used in children under 6 months. For older children, ibuprofen tends to last longer (6–8 hours versus 4–6 hours for acetaminophen) and also reduces inflammation, which makes it better for pain from injuries, sunburns, or sore muscles. If you are unsure which is right for your child, call Spring Valley Pediatrics at 202-966-5000.

Yes — alternating acetaminophen and ibuprofen is a common and effective strategy for managing persistent or high fevers in children over 6 months. Because the two medications work differently and are processed through different pathways, alternating them allows more continuous fever control without exceeding the safe dosing interval for either drug. A typical approach is to give one medication, then give the other 3–4 hours later, then return to the first. Always use weight-based dosing (see the charts above) and call Spring Valley Pediatrics if your child’s fever is not responding or if you have questions about timing.

Always dose by weight, not age. The dosing charts on this page show the correct amount for your child’s current weight. Use the measuring device that comes with the medication — never a kitchen spoon. If your child is between weight ranges, use the dose for the lower weight. If your child has recently gained weight, recalculate the dose — what was correct six months ago may now be too low.

Acetaminophen may be given every 4–6 hours as needed. Do not give more than 5 doses in 24 hours. Always wait the full interval between doses — giving it too frequently, even at the correct per-dose amount, can cause liver damage.

Ibuprofen may be given every 6–8 hours as needed. Do not give more than 4 doses in 24 hours. Do not give ibuprofen to children under 6 months, and use with caution in children who are dehydrated or vomiting significantly — contact our office in those cases.

Be very careful. Many over-the-counter cold and cough medicines already contain acetaminophen. Giving Tylenol on top of a cold medicine that includes acetaminophen can cause an accidental overdose. Always read the full ingredient list on any multi-symptom cold medicine before combining it with Tylenol. If you are unsure, call us before giving both.

Call Spring Valley Pediatrics at 202-966-5000. A fever that does not respond to appropriate doses of acetaminophen or ibuprofen, or a fever above 104°F, or a fever in a child under 3 months of age warrants a call regardless of what medications have been given. Do not increase the dose beyond the weight-based chart in an attempt to bring the fever down faster.

Call Poison Control immediately at 1-800-222-1222 — available 24 hours a day, 7 days a week. Do not wait for symptoms. Acetaminophen overdose is particularly serious because liver damage may not be apparent for 24–72 hours. If your child is unconscious, having difficulty breathing, or having a seizure, call 911.

No. Ibuprofen is not recommended for infants under 6 months. For fever or pain in babies under 6 months, use acetaminophen at the appropriate weight-based dose. For babies under 3 months with any fever above 100.4°F, call Spring Valley Pediatrics or go to the emergency room immediately — do not treat with medication and wait.

Not necessarily. Fever is the immune system’s response to infection and is not dangerous in most healthy children. The goal of medication is comfort — helping your child feel well enough to drink fluids and rest — not achieving a normal temperature number. If your child has a fever but is drinking fluids and is reasonably comfortable, it is acceptable to monitor without immediately giving medication. Call us if the fever is above 104°F, lasts more than 3 days, or your child seems very ill.
