The Risks of Patient Pill Splitting: A Case Report and Review.

The cutting or splitting of pills can be used by patients to create an intermediate dose or to save money in situations where a higher dose is priced at relatively the same cost as a lower dose. A number of studies of selected medications have concluded that pill splitting in general can be done without adverse effects, with the exception of enteric-coated medications and extended-release medications. Individual patients should be assessed for evidence of patient understanding, as well as the physical abilities for pill splitting. Here, we present the case of a patient whose lack of understanding and inability to organize the pill-splitting process led to poor control of her hypertension, resulting in an emergency department (ED) evaluation.
