Health Canada is changing its labelling standards on over-the-counter acetaminophen products due to concerns over potential liver damage. Packaging will include “clearer instructions and stronger warnings” to help consumers use the products more safely, the agency said in a statement on its website. Acetaminophen is a drug frequently used in headache and pain medications, cold remedies, allergy medicines and opioid pain relievers. Taking too much acetaminophen or taking it for too long can lead to complications including liver damage, liver failure and even death. The new labelling will emphasize taking the lowest effective dose, not exceeding the recommended daily maximum, using them for no more than five days for pain and three for fever, and not consuming more than two alcoholic drinks in a day while taking acetaminophen. Labels will also display the words “contains acetaminophen” in bold, red text in the top right corner. They’ll also need to include a “Drug Facts” table with instructions, warnings and safety information. They also recommend that children’s liquid products include a calibrated dosing device, so caregivers can make sure they give kids the right amount. Health Canada will also send a notice to companies discouraging them from including acetaminophen in quantities greater than 325 milligrams. The changes come into effect immediately, and companies with products already on the market will have 18 months to update their product labels.
