INTRODUCTION: there is a large amount of drugs with visual, phonetic or spelling similarities in their trade names and/or active ingredients that create operational and medication errors and could cause harm to patients. This problem is known by the acronym LASA (Look-Alike, Sound-Alike). OBJECTIVE: to identify LASA medicines and/or active ingredients in the Argentine pharmaceutical market. METHOD: the international and national literature on LASA was reviewed. Then a search of trade name and generic medicines in the Alfabeta®, Kairos® and Manual Farmacéutico® internet databases was conducted during July 2008. The researchers surveyed the visual aspect of medicines in their premises work and generated a photographic archive. In addition, a LASA error voluntary report system was implemented and subjected to analysis in order to characterize the factors involved in LASA problem. RESULTS: 927 sets of LASA medications were found among 20.517 medicines assessed and 80 LASA errors were reported through the report system. CONCLUSION: LASA medicines are a public health problem in Argentina. Their detection, communication and prevention are needed to avoid negative consequences for patients.
