Background: Since November 2012, some of over-the-counter (OTC) medications have been sold in convenience store withoutpharmacist' s supervision. We purposed to examine if the product labels of OTCs provide sufficient information that is appropriatefor consumers who may have low health literacy. Methods: We compared the difficulty of words that are utilized in pharmaceuticalproduct labels of interest (intervention) with those in the 6th grade textbook (control). Pharmaceutical products of interest werecomprised of 13 OTCs which have been sold currently in convenience stores. We grouped words into the 4 levels of difficulty basedon the Korean Vocabulary Classification for Education, and statistically tested words frequency in each level between OTCs andcontrol. Results: The 13 OTC labels included lay language (easier or equal to language used in primary school) about 10% less;professional language about 10% more (p < 0.001 in all). Labels for analgesics had the longest and most difficult information,followed by common cold preparations, muscle pain relievers as plaster or cataplasma and digestives. Conclusion: The 13 OTClabels might fail to provide appropriate information for safety use by consumers in terms of the difficulty level of words. Theimprovement of labels of OTC medications and consumer education strategies are called for safety use of OTC medications sold inconvenience stores.
