Indications: Treatment of fever and pain. Give every 4-6 hours as needed, no more than 5 times in 24 hours.

NOTES:
1)CAUTION: In May, 2011, a move to one standard concentration (160 mg/5 ml) of liquid acetaminophen medicine for infants and children was announced. Up until this point, there have been mainly 2 concentrations: 80 mg/0.8 ml (Infant Concentrated Drops) and 160 mg/5 ml (Children's Liquid Suspension or Syrup). During this transition period, both old and new concentrations of infant acetaminophen may be available on store shelves and in homes. Before selecting a dose, please double check the infant package carefully to find the correct concentration. Then, select the dosage according to the concentration and child's weight.
2) Dosing is based on WEIGHT, not age. Keep note of your child's most recent weight.
3) Suppositories come in 80, 120, 325, and 650 mg doses. For the rectal dose, use the oral dose. These are over the counter and do not require a prescription.
4) Use a proper measuring device. For infant drops, only use the dropper provided in the package. For children's suspension, use the medicine cup or a special medicine syringe. A kitchen teaspoon is not accurate enough.
5) DO NOT GIVE TO INFANTS < 8 weeks of age without speaking to a physician. Fever in a child less than 8 weeks of age needs a full evaluation regardless of the time of day.
6) WARNING: Be aware that many over-the counter (OTC) medications such as cold preparations may contain acetaminophen, which can lead to double dosing. Read all OTC labels carefully. The FDA advises against using multi-ingredient OTC medications in children less than 6 years of age.
