Managing multiple medications

Medication lists grow by addition and rarely by subtraction, which is how people end up taking a dozen things nobody has considered as a whole.

Why it accumulates

Each prescription is reasonable in isolation.

A condition is diagnosed and treated; a side effect appears and is treated with another drug; a specialist adds something without seeing the whole list; a hospital admission adds more; and nothing is ever formally stopped.

The prescribing cascade — treating a side effect as a new condition — is a well-described and common mechanism.

Guidelines are written for single conditions and applied to people with several, which multiplies the recommended drugs.

And discontinuation requires an active decision that nobody owns.

Why it matters

Beyond cost.

Interaction risk rises steeply with the number of medications.

Adverse drug reactions account for a substantial proportion of hospital admissions in older adults, and a considerable share of those are preventable.

Falls, confusion, kidney injury and bleeding are common consequences.

Adherence falls as complexity rises.

And the cost, in copayments or to the system, compounds.

Structured medication review

The intervention that addresses it.

Available as a defined service in many health systems, delivered by pharmacists or prescribers.

What it should cover: what each medication is for; whether the original indication still applies; whether it is working; whether the dose is right for current kidney and liver function; whether any drug is treating a side effect of another; interactions; adherence; and the patient's own priorities.

Several validated tools exist to identify potentially inappropriate prescribing in older adults, which clinicians use to structure the review.

Requesting one is entirely reasonable, and take-up is far below eligibility.

Deprescribing

Stopping medicines deliberately and safely.

Common candidates: proton pump inhibitors continued indefinitely after a short-term indication; sedatives and sleeping tablets prescribed for a temporary problem years earlier; anticholinergic drugs, whose cumulative burden is associated with cognitive effects and falls; and preventive medications whose benefit horizon exceeds a person's likely life expectancy.

The essential rule: deprescribing is done with a clinician, one drug at a time, with a plan for tapering where needed and for monitoring what happens.

Several drugs cannot be stopped abruptly — including benzodiazepines, some antidepressants, beta blockers, steroids and anti-epileptics — where sudden cessation is dangerous.

Practical systems that help

For anyone taking several medicines.

A single written list, kept updated, including doses, timings, what each is for and any allergies.

Carry it, photograph it, and bring it to every appointment and admission.

A weekly pill organiser, which remains one of the most effective adherence aids studied.

Blister packs dispensed by the pharmacy where organisation is difficult.

Synchronising all prescriptions to a single date so everything is collected together.

Simplifying to once-daily formulations and combination tablets where clinically equivalent.

Linking doses to existing daily routines rather than to clock times.

And alarms or apps as a supplement rather than a substitute for a physical system.

Transitions of care

Where errors cluster.

Hospital admission and discharge are the highest-risk points for medication error, with discrepancies between what a person was taking and what appears on the discharge list being common.

Practical protection: take your written list to hospital; ask for a full explanation of what has changed at discharge and why; check the discharge list against your previous list line by line; and ask the community pharmacy to review it.

Ask specifically whether anything is intended to be temporary, since short courses frequently become permanent by accident.

Cost management

Which interacts with everything above.

Cost-related non-adherence — skipping doses, delaying refills, not filling prescriptions — is common and produces worse outcomes and higher total costs.

Tell the prescriber if cost is a problem, since they generally do not know and frequently have alternatives.

Ask about generics, therapeutic alternatives, longer prescription durations, prepayment schemes and exemptions.

Order only what you need on repeat prescriptions, since unused medicines represent substantial waste.

And request a review specifically to reduce the number of items, which is a legitimate reason to ask.

Questions worth asking about every medicine

Periodically.

What is this for, and how would I know if it is working?

What happens if I stop it?

Is it still needed?

Is this dose right for me now?

Is anything on this list treating a side effect of something else on this list?

And which of these matters most, if I could only manage a few?

That last question is uncomfortable and is exactly the one that structured reviews are designed to answer.

General information only, not medical advice. Never stop prescribed medication without consulting a clinician — some drugs are dangerous to stop abruptly.
