Medications · Elderly Care · NHS Services
If your parent comes home from a hospital stay with three new prescriptions on top of the ones they already take, it can be hard to know whether anyone has thought about how all of those medications work together.
Five or more regular medications is common among older adults in the UK, and the combination can bring real risks: missed doses, side effects that are hard to distinguish from ordinary ageing, and interactions that nobody flags until something goes wrong. This guide covers what the risks actually are, what the NHS offers to help, and what practical steps you can take — including some that don't require a GP appointment at all.
How common is this?
Taking five or more medicines regularly at the same time is common enough that it has its own clinical term: polypharmacy. It isn't always a problem — someone managing diabetes, high blood pressure, high cholesterol and a heart condition may genuinely need every prescription they have. But the risk rises with the number of medicines, and it tends to go unreviewed for longer than it should.
The risks aren't theoretical: research from a large UK teaching hospital suggests that adverse drug reactions often go unrecognised when they show up as a fall, confusion, or unusual fatigue. And many people are simply never asked whether they'd want to reduce their medicines.
Signs that medication management may need attention
These aren't clinical red flags — they're things an adult child can observe without any medical knowledge. If several apply to your parent's situation, it's probably worth raising with their GP or pharmacist.
- Doses are being missed or taken inconsistently. A weekly pill organiser that's full on the wrong days, or blister packs that aren't running down at the expected rate, can be a quiet signal.
- Some packs run out faster than others. If your parent is on four medicines from the same prescription but one always runs out first, they may be taking it more often than directed — or the others less often.
- A new symptom appeared after a new prescription. Unexplained tiredness, dizziness, changes in appetite or unusual confusion that started around the same time as a new medication are worth mentioning to a pharmacist, even before going back to the GP.
- Medications have been prescribed by several different doctors without obvious coordination. A GP, a cardiologist, a rheumatologist and an orthopaedic consultant may all be adding to the list without any one person looking at the whole picture.
- Your parent doesn't know what a particular medication is for. People are more likely to take a medicine consistently if they understand why they're taking it.
- Medicines are stored haphazardly. A mix of old and new boxes in different rooms, some past their expiry date, suggests the management of the whole regime has drifted.
What the NHS offers — the structured medication review
This is the part most people don't know exists.
What is a structured medication review?
A structured medication review (SMR) is a NICE-approved, comprehensive assessment of everything a patient is taking, carried out by a clinical pharmacist working within a GP practice. It isn't a quick check — it's a proper conversation about what each medicine is for, whether it's still necessary, whether the dose is right, and whether anything could be safely reduced or stopped.
SMRs are available on the NHS, free of charge. The catch is that they're significantly underused: a large study of patients with polypharmacy in North West London found that only around 17% of eligible patients had actually received one. Most people simply don't know they can ask for it.
Who is typically prioritised: people with complex or problematic polypharmacy — particularly those on many medicines, living with frailty, or whose medication regime hasn't been reviewed recently; those taking medicines associated with a higher risk of dependence, including opioids, gabapentinoids and benzodiazepines; and anyone whose medicine regime has become complex following hospital discharge or a new diagnosis.
If your parent hasn't had a full medication review in the past year, it's worth calling the GP practice and asking directly whether a structured medication review can be arranged with the clinical pharmacist.
The pharmacist alternative
For something less formal, any community pharmacist can provide a Medicines Use Review for free — a shorter conversation, but useful for checking whether a medicine is being taken correctly and whether anything obvious needs flagging. No appointment is usually needed.
What you can do between reviews
A structured review is the right clinical step. In the meantime, there are practical things that reduce the day-to-day risk.
- A weekly dosette box. The simplest and most consistently effective tool. A pill organiser with a compartment for each day means it's immediately obvious whether a dose has been taken. Many pharmacies will fill a weekly dosette box for your parent as part of their regular dispensing service, often at no extra charge.
- A written medication list. An up-to-date list of everything your parent takes — name, dose, frequency, and what it's for — that goes with them to every appointment. NHS guidance recommends this explicitly, but many older people don't have one. A single sheet of paper kept in a wallet can prevent duplication and avoidable prescribing errors.
- A medication reminder app. Several UK-accessible apps send alerts when it's time to take a tablet. For someone already comfortable with their smartphone, this can work well alongside a dosette box.
- An automated medication dispenser. For higher-risk situations — someone living alone, with memory difficulties, or a complex schedule — an electronic dispenser can be programmed to release the right dose at the right time and sound an alert if it isn't taken. Available to buy privately and through some social care providers.
Checking for interactions
If you want to understand whether a particular combination of medicines might interact, the British National Formulary (BNF) interaction checker at bnf.nice.org.uk is the official NHS resource. It was written for healthcare professionals but is publicly accessible.
For a personalised assessment of your parent's full list, a community pharmacist is the most accessible and most appropriate first step. They can see the dispensing history, know what's been prescribed by whom, and can flag concerns directly. This conversation doesn't need to be booked and is free.
What to discuss at the next GP appointment
If you're helping your parent prepare for a GP appointment — or going with them — these are the questions most worth raising:
- “Has my parent had a structured medication review recently — and if not, can one be arranged?”
- “Is every medication on the current list still necessary?”
- “Could any of the symptoms they've been having be related to a medication they're taking?”
- “Are there any known interactions between the medicines currently prescribed?”
- “Could the pharmacy provide a weekly dosette box as part of the dispensing service?”
Not sure which NHS service your parent actually needs?
The Hea Navigator matches people to the right NHS service based on what they describe in their own words — from structured medication reviews and clinical pharmacist appointments to other local health and care services. It's free, needs no account, and works in 10 languages.

How many medications is too many for an elderly person?
There's no fixed number. Polypharmacy is defined as five or more, but the question isn't the count — it's whether each medicine is still justified and whether the combination is being monitored. Someone on eight well-reviewed medicines may be better managed than someone on four that haven't been looked at in years.
Can I ask for a medication review on my parent's behalf?
Yes. Family members can contact a GP practice to raise concerns and ask whether a structured medication review can be arranged. The review itself is a conversation with your parent — but there's no reason you can't prompt the referral.
Is there a free drug interaction checker online?
The BNF interaction checker at bnf.nice.org.uk is the official NHS tool, freely available. For a personalised assessment of your parent's full list, a community pharmacist is a better first step — they can look at the whole picture in context.
What is a dosette box and how do I get one?
A dosette box is a weekly pill organiser with compartments for each day, sometimes each time of day. Many pharmacies supply and fill them as part of their dispensing service. Ask at your parent's regular pharmacy first — it's often free.
