Older adults often carry the heaviest medication load of any patient population, and that load is where much of the bedside risk lives. Every extra drug adds a chance for an interaction, a side effect, or a missed dose, and the nurse is usually the first person positioned to notice when something is off.
Polypharmacy is commonly described as the regular use of five or more medications, though the safer working definition centers on appropriateness rather than a count. A patient on six well-indicated, well-tolerated drugs may be fine. A patient on four that no longer match their goals of care may not be. AHRQ frames the core safety concern plainly: deprescribing exists because potentially inappropriate medications accumulate over time and the risk of adverse drug events rises with each additional medication. Your job is not to decide what to stop. Your job is to surface the signals that prompt a review and to keep the patient safe while prescribers and pharmacists act on them.
Start with an honest medication reconciliation
Reconciliation is the foundation of every polypharmacy strategy, and it is where nursing rigor pays off most. An accurate list is the first step of the structured deprescribing approach AHRQ describes, and it depends on more than copying the prior chart.
- Ask the patient to bring everything, including over-the-counter products, supplements, herbals, eye drops, topicals, and inhalers. The "brown-bag" review catches what the EHR misses.
- Cross-check multiple sources: discharge notes, the home list, and pharmacy fill history. Discrepancies between these often reveal the real problem.
- Clarify what the patient actually takes versus what is prescribed. Skipped doses, doubled doses, and expired bottles change the clinical picture.
- Watch for duplication across specialists. Multiple prescribers and no single primary coordinator is a well-recognized driver of polypharmacy.
Document discrepancies clearly. A reconciliation that names a conflict is far more useful to the team than a tidy list that hides one.
Know the high-risk drugs and what to monitor
Certain classes account for a disproportionate share of harm in older adults, and the StatPearls review on reducing polypharmacy names them directly: anticholinergics, sedatives and anxiolytics, opioids, and cardiovascular agents, along with NSAIDs and proton pump inhibitors. These deserve focused nursing attention.
- Anticholinergics contribute to delirium, memory loss, urinary retention, and falls. The burden is cumulative across many common drugs, so the total anticholinergic load matters more than any single agent.
- Sedatives and anxiolytics raise the risk of confusion, fractures, and dependence.
- Opioids carry respiratory and dependency risk, especially when combined with sedatives.
- Cardiovascular agents can drive hypotension and dizziness, feeding the fall cycle.
The drugs most likely to be inappropriate in an older adult are often the same ones most likely to put that patient on the floor.
This is where screening criteria help the team. The AGS Beers Criteria and the STOPP criteria flag medications associated with adverse events in older adults. The American Geriatrics Society 2023 update to the Beers Criteria is the current reference many facilities use. You are not expected to apply these lists unilaterally, but recognizing a Beers-listed drug on your patient's profile is a legitimate reason to raise the question during rounds.
Support deprescribing safely, then watch closely
When the team decides to taper or stop a medication, the post-change window is a nursing responsibility. Deprescribing is supervised discontinuation, not abrupt withdrawal, and several principles protect the patient:
- 1Change one medication at a time so any new symptom has a clear cause.
- 2Expect gradual tapering for drugs with withdrawal or rebound potential, such as benzodiazepines, opioids, beta-blockers, and proton pump inhibitors.
- 3Monitor for the specific symptom the drug was treating, and for withdrawal effects, during short-interval follow-up.
- 4Close the communication loop. Stopping a drug in the EHR does not automatically reach the outpatient pharmacy, so the change must be communicated directly to avoid an unintended refill.
Document the reason for each change. A note that explains why a drug was stopped prevents a future clinician from restarting it reflexively.
Make the patient a partner
Deprescribing works best as shared decision-making, not something done to the patient. Older adults and caregivers may fear that stopping a drug means their care is being withdrawn, so framing matters.
- Explain that fewer, better-matched medications is a form of better care, not less care.
- Help the patient keep a current, written medication list and bring it to every visit.
- Teach which new symptoms to report after a change, and how to reach the team.
- Confirm understanding of timing, devices, and any taper schedule before discharge.
Interprofessional collaboration ties it together. Pharmacists lead comprehensive medication reviews, prescribers make the final call, and nurses provide the continuous assessment, education, and monitoring that make a deprescribing plan safe in practice. Always follow your facility's policy and escalate concerns through the established chain rather than adjusting medications independently.
