Pharmacy Care for Older Adults

PharmaSim · Created · Updated

Educational material; no clinical peer review is claimed. Methodology and limitations

Older adults are the population most exposed to medicines and most vulnerable to medication harm. They often see multiple prescribers, take several drugs, and have age-related changes in how the body handles medicines. The pharmacist is well placed to coordinate care and reduce preventable harm. This article covers the population perspective; the companion polypharmacy article addresses cumulative medication risk in detail.

Why this population needs special care

Ageing changes body composition, liver function, kidney function, and nervous system sensitivity. Falls, bleeds, confusion, and hypoglycemia are common medication-related harms in older adults. The more medicines a patient takes, the higher the risk, often because of the combination rather than any single drug.

Physiological changes that matter

Reduced kidney function is common even when creatinine looks acceptable, because muscle mass falls with age. This means renally cleared drugs may accumulate. Increased sensitivity to sedating and anticholinergic drugs means smaller effects can cause falls or confusion. Altered body composition changes how some drugs distribute.

Cognitive and functional considerations

Memory, sight, and dexterity affect whether a patient can follow a regimen. A complex schedule with many tablets is harder to manage and more prone to error. Involving a carer with consent, simplifying the regimen with the prescriber, and using adherence aids are part of the pharmacist's role.

Falls prevention and medication

Some medicines increase fall risk: antihypertensives causing postural hypotension, sedatives, first-generation antihistamines, and drugs with anticholinergic effects. Counselling on standing slowly, reviewing timing of blood-pressure medicines, and flagging fall-risk drugs for a prescriber review are practical steps.

Counseling adapted to this population

Use plain language, check understanding with teach-back, and confirm the patient can open containers and read labels. Maintain a single, current medication list that includes OTC and herbal products. Invite the patient to bring all medicines to one place for reconciliation, with a carer present if the patient agrees.

When to refer

A fall with head injury while anticoagulated, new confusion, signs of bleeding, or recurrent hypoglycemia need urgent assessment. A medication regimen that is too complex to manage safely warrants a structured review with the prescriber.

Practical example

An older patient with dizziness and many medicines

A 78-year-old taking seven medicines mentions dizziness on standing. The pharmacist reconciles the list, identifies postural hypotension as a likely contributor, advises standing slowly, and flags the concern to the prescriber for a formal review rather than changing any prescription independently. Safety advice is given while the review is arranged.

Key takeaways

  • Older adults are most exposed to medicines and most vulnerable to medication harm.
  • Kidney function can be reduced even when creatinine looks normal.
  • Some medicines increase fall, confusion, and bleeding risk.
  • A single current list and a structured prescriber review reduce harm.
