Most adults accumulate medications the way a house accumulates cables behind the desk. Each addition was reasonable at the time. Together, over years, they become a tangle whose original purpose no one has recently examined. A structured medication review, done at least annually, is one of the highest-yield conversations in preventive medicine, and it is quietly skipped in most primary care visits.
The goal is not to stop everything. It is to ask, for each item, whether the indication still applies, whether the dose is still right, whether the drug still outperforms available alternatives, and whether an interaction has developed that wasn't there before.
Why annual review earns its time
Prescriptions started for a specific condition often continue past the point where they help. Proton pump inhibitors intended for a short course become a decade of therapy. A sedative introduced during a rough stretch persists indefinitely. A blood pressure agent added when kidney function was different than it is now becomes a fall risk.
Several patterns appear again and again in reviews:
- Duplicate therapy across specialists who did not know about each other's prescriptions.
- Prescribing cascades, in which a side effect of one drug prompts a second drug rather than reconsideration of the first.
- Dose creep, particularly in psychiatric and pain medications, without a scheduled reassessment.
- Renally cleared drugs at doses that made sense when kidney function was higher.
- Over-the-counter and supplement combinations that meaningfully interact with prescribed drugs.
A medication reconciliation captures these. It requires that the patient bring everything they actually take, prescribed or not, and that the clinician examine each item rather than accepting the chart list at face value.
Deprescribing: an actual field
Deprescribing is the deliberate stopping or reduction of a medication that no longer offers net benefit. It is not casual withdrawal. Some drugs require taper, some have rebound effects, and some are appropriate long-term but were never reviewed for continued fit.
Medications that reward periodic reassessment include:
- Benzodiazepines and Z-drugs, particularly in older adults, where they raise fall and cognitive risk.
- Anticholinergics (many antihistamines, some bladder drugs, older antidepressants), which accumulate cognitive burden.
- Long-term opioids, where risk-benefit shifts substantially over time.
- Proton pump inhibitors past initial indication.
- Statins in patients with limited life expectancy for primary prevention.
- Anti-hypertensives if home readings suggest over-treatment or postural drops.
- Diabetes medications, particularly sulfonylureas and insulin, that may drive hypoglycemia in older adults with tightening A1c targets.
The Beers Criteria and the STOPP/START tools list medications that carry specific risks in older adults and offer a structured way to review a list.
A medication that no one has questioned in five years is either a treasured ally or a piece of forgotten furniture. Only a review can tell you which.
How to make a review actually happen
Most review does not happen because no one schedules it. A few tactics help.
- Ask for a dedicated medication review appointment, distinct from a symptom-focused visit. Some primary care practices bill this as a separate service.
- Bring everything: prescription bottles, over-the-counter drugs, supplements, herbal products, topicals, eye drops, and anything used only occasionally.
- Bring the list of pharmacies you use. Fragmented pharmacy use is one of the most common sources of missed interactions.
- Ask a pharmacist, in addition to a physician. Community pharmacists and Medicare-covered Comprehensive Medication Reviews for eligible patients are underused resources.
- Ask about each medication whether the original indication still applies, whether the dose is still appropriate, and whether there is a simpler regimen.
Request that any changes be documented in the after-visit summary, with a clear plan for taper, monitoring, or return visit as appropriate.
Special cases worth raising
A few situations especially reward proactive review.
- After a hospitalization: discharge medication lists are often incorrect and frequently contain drugs meant only for the hospital stay.
- After a new diagnosis that changes physiology: kidney disease, heart failure, pregnancy planning, cancer treatment.
- After age 65, when accumulated drug burden and altered pharmacokinetics interact.
- Before elective surgery, when several medications need to be paused, dose-adjusted, or bridged.
- When starting a new supplement, since many interact with prescribed drugs in ways patients underestimate.
The bottom line
Medication reviews are one of the clearest examples of preventive care that is nearly free, requires no new technology, and consistently improves outcomes. Once a year, at a scheduled visit, bring every pill you take and ask, for each one, whether it still earns its place.
