About Drug Identification Number (DIN)

A Drug Identification Number (DIN) is a computer-generated digit number, assigned to a drug product prior to being sold in Canada. Health Canada regulates OTC (Over-the-counter medicines sold directly to consumers without a prescription) drugs to ensure they are safe to use and decrease health risks of Canadians. In USA, FDA carries out a regulatory review of OTC drugs based on active pharmaceutical ingredients and labelling. More than 300,000 OTC drug products are available in the US market.
