Safe Medication Use for Older Adults: What Patients and Families Need to Know

When Medication Becomes Complicated

Taking several different medications every day, prescribed by different specialists for different conditions, is a reality for many older adults in the UK. Around 40% of people over 65 take five or more medications daily, a situation known as polypharmacy. While each medication is prescribed for good reason, the combination creates complexity that carries real risks: interactions between drugs, cumulative side effects, doses that were appropriate years ago but less so now, and the practical challenges of remembering what to take when.

This guide is for older adults and their families who want to manage medications more safely, have better conversations with health professionals, and understand what to watch for when something does not feel right.

The Risks of Polypharmacy

Drug interactions occur when one medication affects how another works. Some interactions reduce the effectiveness of a drug; others increase it to potentially dangerous levels; others produce entirely new effects not associated with either drug alone. The more medications someone takes, the more possible interactions exist, and the complexity grows faster than most people realise.

Side effects that affect older adults disproportionately include dizziness and balance problems, which increase falls risk significantly. Falls in older adults are a major cause of serious injury and hospitalisation, and a significant proportion are medication-related. Certain blood pressure medications, sedatives, antidepressants, and some bladder medications all carry falls risk that should be weighed carefully against their benefits.

Cognitive effects are another significant concern. Some medications, including certain antihistamines, bladder medications, antidepressants, and sleep aids, have anticholinergic properties that can cause confusion, memory problems, and cognitive decline with regular use in older adults. These effects can be mistaken for dementia or simply accepted as a feature of ageing rather than identified as medication-related.

Reviewing Your Medications Regularly

NHS guidance recommends that older adults on multiple medications have a regular medication review with their GP or a clinical pharmacist. This review is an opportunity to assess whether each medication is still needed, whether any can be stopped (deprescribing), whether doses are still appropriate, and whether any concerning interactions exist.

If you have not had a medication review recently, you are entitled to request one. Prepare for the appointment by bringing all your medications with you, including over-the-counter drugs, herbal remedies, and vitamins. Many people do not mention these to their doctor, but they can interact with prescribed medications in significant ways. St John's Wort, for example, interacts with a wide range of prescription drugs and is not benign simply because it is herbal.

Ask at each review whether any medication could be safely stopped or reduced. As conditions change and bodies age, medications started years ago may no longer be appropriate or may have accumulated to levels that cause more harm than benefit.

Organising Medications Safely at Home

For anyone taking multiple daily medications, organisation is a safety issue. Missing a dose of a critical medication, doubling up by mistake, or confusing similar-looking tablets can all have serious consequences.

A weekly pill organiser with compartments for each day and time of day is one of the simplest and most effective tools for medication organisation. Preparing a week's supply in advance reduces the cognitive load of daily management and makes it immediately visible if a dose has been missed. Many pharmacies also offer blister-packed or monitored dosage system (MDS) packing, where medications are pre-dispensed into individual compartments, which is particularly helpful for people with memory difficulties.

Keep an up-to-date written list of all medications, doses, and what they are prescribed for. This list should go with you to every medical appointment and to any emergency department visit. In an emergency, medical staff need to know exactly what someone is taking, and a written list is far more reliable than memory under pressure.

Store medications as directed on the label. Many medications should be stored away from heat and moisture, meaning bathroom cabinets are often not the ideal location despite being the traditional choice. Keep medications out of reach of grandchildren or young visitors.

Recognising When Something Is Wrong

New or changed symptoms after starting a new medication, or after a dose change, should always be reported to a GP or pharmacist. Side effects are not something to simply accept. Many are dose-dependent and can be managed by adjustment. Others indicate that a different medication would be better tolerated.

Signs that medication may be causing problems include new dizziness or balance problems, confusion or unusual forgetfulness, changes in bowel or bladder function, skin reactions, changes in mood or sleep, and unexplained fatigue. Any of these in an older adult taking multiple medications warrants a conversation with a health professional rather than simply being attributed to ageing.

Your Pharmacist Is a Safety Resource

Pharmacists are extensively trained in medications and their interactions, and they are one of the most underused health resources available to older adults. They can answer questions about medications that you may not want to take up GP appointment time with, they can check for interactions, and they can advise on the best way to manage a missed dose or what to do if you run out unexpectedly.

If you are regularly prescribed medications, registering with a pharmacy that holds your full prescription record means they can flag potential interactions whenever a new medication is prescribed. Building a relationship with a consistent pharmacist is as valuable as having a consistent GP in the management of complex medication regimens.
