* As of 2011, in an effort to minimize pediatric dosing errors, the Consumer Healthcare Products Association, in conjunction with the US Federal Drug Administration, is phasing out formulations that contain 100 mg per mL (infant acetaminophen drops) so that pediatric liquid preparations obtained in the United States after that time will all contain a concentration of 32 mg/mL (160 mg per 5 mL). However, 100 mg per mL solutions are likely to continue to be given to children from infant acetaminophen drops preparations purchased by caregivers before this phase out.
¶ NOTE: Tenfold dosing errors and toxicity from intravenous acetaminophen have occurred in small children when the calculated dose in mg is INCORRECTLY administered as the volume in mL because the concentration of the solution is 10 mg/mL. In the United States, intravenous acetaminophen is not licensed for use in children under two years of age.
