Older adults frequently take many medications, with two-fifths taking 5 or more. While most older adults are exposed to polypharmacy as part of evidence-based treatment of 1 or more chronic conditions, with a rising tide of medications comes higher risk of adverse drug events. One strategy to prevent harms associated with polypharmacy is to identify medications that are unnecessary or inappropriate and proactively deprescribe them. The American Geriatric Society Beers Criteria1 and similar lists have provided a starting point for identifying medications that are most often inappropriate in older adults. However, the appropriateness of many other medications is highly dependent on the clinical context of the individual patient. One potentially valuable strategy for deprescribing efforts is to identify common prescribing cascades, instances in which a second (potentially avoidable) medication is administered in response to an adverse effect or drug reaction caused by another medication. In this issue of JAMA Internal Medicine, Savage and colleagues2 describe an example of a prescribing cascade: the prescription of loop diuretics following calcium channel blocker initiation.2
