WEDNESDAY, May 18 (HealthDay News) -- U.S. health advisers recommended Wednesday that dosing instructions should be added to the labels of medicines containing the widely used pain reliever and fever reducer acetaminophen to better protect children under the age of 2.
In a 21-0 vote, the panel of U.S. Food and Drug Administration advisers called for adding dosing information for children 6 months to 2 years old to over-the-counter medicines such as Children's Tylenol and similar products containing acetaminophen, the Associated Press reported.
Currently, the labels of such medications have dosing instructions for children aged 2 and up. For kids under 2, the labels on the liquid medicines simply tell parents to "ask a doctor."
The FDA advisers said the lack of specific dosing recommendations can lead to confusion, with parents unintentionally giving too much of the medicine to children under age 2. Acetaminophen-related overdoses are most common among children younger than 2, and have increased over the past decade, according to FDA data.
Wednesday's vote focused only on a small group of single-ingredient products, including J&J's Children and Infants' Tylenol, Novartis' Triaminic, Prestige Brands' Little Fevers and assorted drugstore brands, the AP said.
In a second vote Wednesday, the panel recommended unanimously that these medicines should also include dosing information based on children's weight -- considered the most accurate way to determine the proper dose. Nearly all over-the-counter manufacturers already include a dosing table with both weight and age. But the FDA advisers said instructions must emphasize that weight is the preferred approach, the AP reported.
While the FDA is not required to follow the recommendations of its advisory panels, it usually does so.
The American Academy of Pediatrics (AAP) and drug manufacturers are both strongly in favor of giving parents the additional dosing information.
"If we give parents better information, they will be able to give enough of the medicine to work well, at the same time minimizing the side effects," said Dr. Daniel Frattarelli, a pediatrician in Dearborn, Mich., who chairs the academy's drug committee and who planned to testify before the joint, two-day meeting of the FDA's Nonprescription Drugs Advisory Committee and the Pediatric Advisory Committee.
"Parents want to do the right thing for their children," he said. "We as a medical community have to give them that information so they are able to do this."
Although the evidence shows that acetaminophen is safe for young children, parents have to be careful with it, pediatricians noted. Giving too much can be toxic to the liver, causing poisoning and even liver failure.
In 2010, there were 270,000 reported overdoses of acetaminophen, according to the American Association of Poison Control Centers. Dosing errors involving children's acetaminophen products accounted for almost 7,500 cases -- nearly 3 percent.
In an ideal world, the parents of infants and toddlers would still consult with their pediatrician or pharmacist to get the proper medication dosing, said Dr. William Basco, director of general pediatrics at the Medical University of South Carolina.
But the reality is that many parents aren't doing that and are instead guessing about proper dosing. "There is no benefit to having parents guess at the right dose," Basco said.
Drug makers, including McNeil Consumer Healthcare, which makes Tylenol, also support the change.
"McNeil is committed to encouraging the appropriate and safe use of medicines in children, including adding new dosing information on the OTC pediatric acetaminophen label to assist caregivers and health-care providers in appropriately dosing children, especially those 6 to 23 months of age," the company wrote in materials submitted to the FDA.
By way of comparison, drugs containing ibuprofen -- another heavily used over-the-counter fever reducer -- already include dosing information for children under age 2.
