The Consumer Healthcare Products Association which is the chief trade group for OTC drug manufacturers said the move was intended to reduce dosing errors.

"CHPA member companies are voluntarily making this conversion to one concentration to help make it easier for parents and caregivers to appropriately use single-ingredient liquid acetaminophen,” said CHPA CEO Scott Melville.

Earlier this week, the FDA released a final guideline document for OTC liquid manufacturers stating all such products should be packaged with calibrated dosing devices.

Several studies have revealed that children receive improper doses of OTC liquid medicine because parents use household spoons or because the dosages devices included in packaging are not easy to read.

Our advice? Always read medication labels and use proper devices that accurately measure dosage.
