Acetaminophen and Ibuprofen Dosages

Use this information as a guideline for caring for your child. Your doctor may decide to adjust the dosage as appropriate for your child. Please remember to keep all medications out of your child’s reach at all times.

Acetaminophen (Tylenol)

Acetaminophen reduces fever and relieves pain. Typical uses include fevers, immunizations, teething, earaches, bruises, headaches, etc. Please notify us prior to using Tylenol for babies under 2 months of age.


Note! As of July 2011, infant concentrated drops are being phased out in the United States and replaced with less-concentrated form of the medicine. The concentrated drops are still safe to use as long as the dose is correct. The old form is three times as concentrated as the new infant medicine, so use caution: Know your child's weight and follow the dosage chart.

Acetaminophen is available in the following forms:

  • Old infant drops: 80 mg/0.8 ml per dropper (shake well before using)
  • New infant liquid: 160 mg/5 ml per included syringe (shake well before using)
  • Children's chews or meltaways: 80 mg each
  • Junior-strength chews or meltaways: 160 mg each
  • Adult regular-strength tablets: 325 mg each
  • Rectal Suppository:120mg

Six Safety Tips for Acetaminophen

  1. Don't give to a baby under 3 months without a doctor's approval.
  2. Don't confuse infant drops with the new infant liquid. (Infant drops are three times more concentrated.)
  3. Always use the measuring device that comes with the medicine.
  4. The proper dosage is based on weight, not age.
  5. 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.
  6. Please remember to keep all medications out of your child's reach at all times.

Ibuprofen (Motrin, Advil)

Ibuprofen reduces fever, relieves pain, and fights inflammation. Typical uses include fevers, immunizations, teething, earaches, bruises, headache, sunburns, sore muscles, etc.

We usually recommend that ibuprofen not be used in babies under 6 months of age.

Ibuprofen is available in the following forms:


- Infant drops (50mg/1.25ml) Note: 1.25 ml = 1 dropper
- Children's liquid (100mg/5ml) Note: 5 ml = 1 tsp

- Junior strength tablets (100mg)
