Medication Information Medication information provided by pharmaceutical companies on OTC medication bottles and package labels may be confusing to parents. Chang, Chen, Chang. and Smith (2011) contended that many parents rely on written information, either in labels or on package inserts, but this ften inconsistent between brands or concentrations of a medication, incomplete and / or difficult for parents to read and understand, especially for individuals with. low levels of reading and / or health literacy. Furthermore, acetaminophen and ibuprofen both come in differ ent concentrations within their own product line for pediatric populations, and the concentrations between products vary. causing considerable confusion for parents when calculating appro- priate safe dosages. Some manufactures and retailers in the United States have addressed this issue by voluntarily removing the more concentrated drops from the market (Federal Drug Administration. 2011 Ironically, changes in medication concentrations to increase consistency and ultimately decrease medication errors may, in fact, increase errors during. the transition period as parents adjust to the changes in the concentrations available and the potentially new volume of medication required for accurate dosing Traynor, 2009; Warner, 2011).
