According to an article on Parenting.com, the U.S. Food & Drug Administration has issued a warning to all parents and caregivers about the potential for dosing errors when giving liquid acetaminophen to infants.
An additional concentration of liquid acetaminophen of 160 mg/5 mL is now available for infants. It had been sold with dosing cups for children ages 2 to 11. But consumers may be more familiar with the 80 mg/0.8 mL or 80 mg/mL concentrations of liquid acetaminophen, which could result in dosing errors, since older concentrations may still be on store shelves or in a family’s medicine cabinet.
The new concentration is less concentrated than earlier forms, which could lead to an infant receiving insufficient medication or making the drug ineffective. Giving too much acetaminophen can possible lead to death, and overdoses of infant acetaminophen, which can lead to death from liver failure, are the reason behind this change.
