How Much Tylenol Is Safe for Your Child?

Giving your child Tylenol®? Too much acetaminophen can cause serious liver damage—even before symptoms appear. Check your child's weight and the concentration on the bottle before every dose.

Quick Answer: What's the Safe Tylenol Dose?

Use your child's current weight and check the exact product strength. In the United States, common Infant's Tylenol and Children's Tylenol liquids both contain 160 mg per 5 mL. The chewable chart applies only to 160 mg tablets. For children younger than 2 years, confirm the dose with your pediatrician before giving it.

Important: For children younger than 2 years, confirm acetaminophen dosing with your pediatrician or another qualified healthcare professional. A rectal temperature of 100.4°F (38°C) or higher in a baby younger than 3 months requires prompt medical evaluation.

Tylenol Dosage Chart by Weight

This chart applies only to U.S. pediatric liquid acetaminophen labeled 160 mg/5 mL and 160 mg chewable tablets. Always read the current Drug Facts label because products, concentrations and directions may change.

Weight Approximate age Liquid 160 mg/5 mL 160 mg chewable
6–11 lb 0–3 months 1.25 mL* Not appropriate
12–17 lb 4–11 months 2.5 mL* Not appropriate
18–23 lb 12–23 months 3.75 mL* Not appropriate
24–35 lb 2–3 years 5 mL 1 tablet
36–47 lb 4–5 years 7.5 mL 1½ tablets
48–59 lb 6–8 years 10 mL 2 tablets
60–71 lb 9–10 years 12.5 mL 2½ tablets
72–95 lb 11 years 15 mL 3 tablets

*Clinician-directed doses only for children younger than 2 years. The starred liquid amounts are not instructions to dose an infant independently. Confirm the dose with your pediatrician. A rectal fever of 100.4°F (38°C) or higher in a baby younger than 3 months requires prompt medical evaluation; do not delay care to give medicine.

Chewable safety: The chewable amounts apply only to products labeled 160 mg per tablet. Follow the exact product directions for minimum age, chewing and any half-tablet doses; do not assume every brand can be split.

Before You Give Tylenol or Acetaminophen

  • Confirm the bottle says acetaminophen 160 mg per 5 mL.
  • Use the syringe or dosing cup supplied with the medicine—never a kitchen spoon.
  • Follow the product label for dose intervals (commonly every 4 hours as needed), and do not exceed 5 doses in 24 hours for the products shown.
  • Prevent accidental overdose: Do not combine Tylenol with another medicine containing acetaminophen (sometimes labeled APAP).
  • For chewables, follow your exact product label. Use half-tablet doses only when the product instructions allow them and your child can chew safely.

What Is Tylenol?

Tylenol is a brand name for acetaminophen, a medicine used to reduce fever and relieve pain. Store-brand acetaminophen may contain the same active ingredient. The correct amount depends primarily on your child's weight and the concentration of the product.

Acetaminophen can make a child more comfortable, but it does not treat the infection or other condition causing the fever. A child's behavior, breathing, hydration and associated symptoms often matter more than the number on the thermometer.

Should I Use Weight or Age for a Tylenol Dose?

Use your child's current weight whenever possible. Children of the same age can differ considerably in size, which is why weight-based dosing is more precise than choosing a dose from age alone.

The ages shown in the chart are approximate and are included as a helpful reference. If you do not know your child's current weight or are unsure which row applies, contact your pediatrician before giving the medicine.

How to Give Acetaminophen Safely

  • Read the active-ingredient and concentration labels every time.
  • Shake liquid medicine if the label instructs you to do so.
  • Measure liquid doses in milliliters with the supplied device.
  • Write down the dose and time, especially when more than one caregiver is involved.
  • Keep all medicines locked away and out of children's sight and reach.
  • Ask before alternating acetaminophen and ibuprofen; complicated schedules can lead to dosing mistakes.

Call Your Pediatrician

  • Before giving acetaminophen to a child younger than 2 years.
  • If you are unsure of the correct product, concentration or dose.
  • If fever lasts more than 24 hours in a child younger than 2 years or more than 3 days in an older child.
  • If your child has liver disease, takes other medicines or has ongoing pain.
  • If your child looks increasingly ill, is not drinking normally or is not improving as expected.

  • A baby younger than 3 months has a rectal temperature of 100.4°F (38°C) or higher.
  • Your child is difficult to wake, has trouble breathing, has a seizure, has a stiff neck or develops a purple rash that does not fade when pressed.
  • You may have given too much acetaminophen or combined multiple acetaminophen-containing products. Call Poison Control immediately, even if your child has no symptoms.

Possible overdose: Call Poison Control immediately at 1-800-222-1222 in the United States. Do not wait for symptoms. Call 911 if the child collapses, has a seizure, has trouble breathing or cannot be awakened.

Dr. G's Pearl

Parents often focus on bringing a fever down to a "normal" number. The goal is comfort, not a perfect temperature. If your child is drinking, interacting and breathing comfortably, that is reassuring. If your child looks seriously ill, seek care regardless of the temperature.

Frequently Asked Questions

How much Tylenol can I give my infant?
Use your baby's current weight and confirm the product concentration. Because labeling directs caregivers to ask a healthcare professional for children younger than 2 years, confirm the dose with your pediatrician. Any rectal temperature of 100.4°F (38°C) or higher in a baby younger than 3 months needs prompt medical evaluation.
What is the Tylenol dosage for a 1-year-old?
A 1-year-old's Tylenol dose should be selected by current weight, not age alone. Children in this age group commonly fall into the 12–17 lb or 18–23 lb rows, but confirm the child's actual weight and the liquid concentration. Because the child is younger than 2 years, confirm the dose with your pediatrician.
How much Tylenol can I give a 2-year-old?
Use your 2-year-old's current weight. A child weighing 24–35 lb corresponds to 5 mL of U.S. liquid acetaminophen labeled 160 mg/5 mL. If the child weighs less than 24 lb, contact your pediatrician before dosing.
Should I calculate children's Tylenol by weight or age?
Weight is preferred because children of the same age can differ substantially in size. Age is only a backup when an accurate current weight is unavailable.
Is a kids' Tylenol dosage based on weight?
Yes. A children's Tylenol dose by weight is more precise than choosing a dose from age alone. Find the child's current weight in the chart, then verify whether you are using liquid acetaminophen 160 mg/5 mL or a 160 mg chewable product.
How often can children take Tylenol?
For children younger than 12, acetaminophen is generally given every 4 hours while symptoms last, but no more than 5 doses in 24 hours. Follow your product's current Drug Facts label and your pediatrician's instructions.
Are Infant's Tylenol and Children's Tylenol the same concentration?
In the United States, current Infant's Tylenol and Children's Tylenol liquid products are commonly 160 mg per 5 mL. Never assume: check the concentration printed on your bottle before every dose, especially with older, imported or specialty products.
Can I alternate Tylenol and ibuprofen?
Do not start an alternating schedule unless your child's healthcare professional recommends it and gives you a clear written plan. Alternating medicines can increase the risk of timing and dosing errors.
What if I accidentally gave too much Tylenol?
Call Poison Control at 1-800-222-1222 immediately in the United States, even if your child looks well. Acetaminophen overdose can cause serious liver injury before obvious symptoms appear.
