In short

Taking five or more medicines (polypharmacy) affects 40% of Australians over 75 and raises both falls risk and cost. The fix is mostly free: keep one complete medicine list including supplements, use one pharmacy, and ask your GP for a free Home Medicines Review. Watch for brand premiums, which don't count toward the PBS Safety Net, and never stop or ration medicine without talking to your doctor.

Our article on preventing falls names medications as one of the biggest and most fixable risk factors — and then, sensibly, sends you to your GP or pharmacist. This is the piece that sits behind that advice, because medicines in later life deserve an article of their own. Take five or more medicines and you have what doctors call polypharmacy (Healthdirect, https://www.healthdirect.gov.au/medicines-safety-for-older-people), and that describes a great many older Australians: among people aged 75 and over, 40 per cent were dispensed more than five medications concurrently in 2022, against an OECD average of 32 per cent — a figure that has been broadly stable since 2016 (Australian Institute of Health and Welfare, https://www.aihw.gov.au/reports/international-comparisons/oecd-health-care-indicators-2022-23/contents/prescribing-in-primary-care). Here's the thing worth understanding from the outset: the problem is almost never any single medicine. Every one of them was probably prescribed for a good reason by a good doctor. The problem is the pile — and the fact that very often, nobody is looking at all of it. This article is general information only, not medical advice. Never change anything you take on the strength of an article; that's a conversation for your GP or pharmacist.

Why does it drift?

Three things quietly build the pile. The first is many prescribers and no single view: you have a GP, you see a cardiologist, maybe an endocrinologist, you had a hospital stay and came home with something new. Each of them is doing good work on their slice of you — and frequently nobody holds the complete list. That's the structural heart of the problem, and it's nobody's fault in particular.

The second is that we add but never subtract. A medicine starts for a solid reason, and then simply keeps going, repeat after repeat, long after the original reason has faded. There's rarely a moment built into the system where someone asks whether it's still needed. And the third is the uncounted extras — the paracetamol, the fish oil, the vitamins, the herbal thing a friend recommended. People don't file these under "medications," so they never mention them, but they can interact all the same.

What is the safety side?

Healthdirect explains why the risk rises with age in two parts: "your body changes with age" and "you are more likely to be taking multiple medicines as you get older" (Healthdirect, https://www.healthdirect.gov.au/medicines-safety-for-older-people). The more medicines you take, the higher the chance of interactions and side effects — and the specific danger for an older person is spelled out plainly: "medicines can have side effects that might make you more likely to fall," with symptoms including "changes to your balance and coordination" and "feeling unsteady or dizzy."

That's precisely why medicines show up on every falls-risk list going. Given that a fall is the single most common event that ends independent living — as our falls article sets out — a medication review is one of the cheapest, highest-leverage things available to you. It's also one of the least used.

What is the money side?

There's a second story here that gets even less airtime: what all this costs on a fixed income, and two levers most people never pull.

The first is the PBS Safety Net. Once you or your family spend a certain amount on PBS medicines in a calendar year you reach the threshold, and your scripts get cheaper for the rest of that year — there are two thresholds, general and concession, and they're updated on 1 January each year (Services Australia, https://www.servicesaustralia.gov.au/keep-track-your-pbs-medicines). Our article on the PBS and the safety nets has the current figures. But two catches matter enormously. It only works if your spending is being tracked, which is your job as much as the pharmacy's: Services Australia's own instruction is that "you need to keep a record of how much you've spent on PBS medicines during the year," and there's a prescription record form you hand to the pharmacist each time you collect a script. If you fill scripts at more than one pharmacy, that record is the only thing joining up your tally. And once you reach the threshold you must actually apply for a PBS Safety Net card — reaching it doesn't discount anything by itself. Combining your family's amounts can get you there sooner.

The second lever is the brand premium. Where a generic version of a medicine exists it contains the same active ingredient, and the government subsidises up to the price of the lowest-priced brand — so if you choose a brand that carries a premium, you pay that premium on top of the co-payment. Here's the part that stings, and that almost nobody knows: the brand premium does not count towards your PBS Safety Net (Pharmaceutical Benefits Scheme, https://www.pbs.gov.au/browse/brand-premium). So the extra you pay for the brand is money that doesn't even move you closer to cheaper scripts later in the year. It's worth simply asking your pharmacist: is there a generic, is it suitable for me, and am I paying a brand premium? Many people have paid that premium for years without ever being asked the question.

What tools fix most of it?

None of these is expensive, and two of them are just habits. They work as a sequence, so here they are as one.

  1. Keep ONE list. Healthdirect suggests a medicines list track "what each medicine (prescription and non-prescription) is for," the dose, when to take it and how (Healthdirect, https://www.healthdirect.gov.au/medicines-safety-for-older-people) — and note that "non-prescription" is doing real work there, so the vitamins and supplements belong on it. Carry it in your wallet. Take it to every appointment, and above all to every hospital admission. If you do one thing from this article, do this: it's the single most useful piece of paper you can own.
  2. Use ONE pharmacy wherever you can. It means somebody is finally seeing the whole picture and can spot a clash — and it keeps your Safety Net tally in one place.
  3. Ask your GP for a Home Medicines Review. A credentialed pharmacist visits you at home, goes through everything you take, and reports back to your doctor. It needs a GP referral, it's free of charge, and you can generally have one every two years (Healthdirect, https://www.healthdirect.gov.au/home-medicines-review). It exists for exactly this problem.
  4. Consider a dose administration aid — a Webster-style pack — if the routine has got complicated. The pharmacy packs each dose by day and time, which takes the guesswork out.
  5. Ask the question at every review: "Do I still need this one?" Reviewing medicines off the list is a real and legitimate part of good care — doctors call it deprescribing. Just note who answers that question: the doctor does. Your job is to ask it.
  6. Know about My Health Record, which can hold your medicines information where treating clinicians can see it in an emergency.

What is the one hard rule?

Healthdirect puts it in capitals, and so will we: "NEVER stop taking your medicine without talking to your doctor" (Healthdirect, https://www.healthdirect.gov.au/medicines-safety-for-older-people). That covers stopping, halving, skipping and changing. Some medicines are genuinely dangerous to stop suddenly, and "I'll just take it every second day to make it last" is a decision that can do real harm.

That applies with particular force to cost. If the money is the problem — if you're looking at a script and quietly deciding to stretch it — say so, out loud, to your GP or your pharmacist. They deal with this constantly, they will not think less of you, and there are very often cheaper options: a generic without the brand premium, a different medicine in the same class, the Safety Net, a different pack size. What there is never a good version of is rationing it yourself in silence.

What do the worked examples show?

These show the same two habits paying off in different currencies. They are illustrative only, and not medical advice.

Consider Margaret, 78, a single full pensioner who takes seven regular medicines prescribed across her GP, a cardiologist and a rheumatologist, plus fish oil and paracetamol she has never mentioned to anyone. She fills scripts at whichever chemist is nearest. On these facts Margaret is squarely in the 40 per cent of over-75s on more than five concurrent medicines (Australian Institute of Health and Welfare, https://www.aihw.gov.au/reports/international-comparisons/oecd-health-care-indicators-2022-23/contents/prescribing-in-primary-care), nobody holds her complete list, and her Safety Net tally is scattered across three pharmacies — so she may be paying full price all year for want of a record. On these facts it is generally rational for someone in Margaret's position to do the two free things first: build one list including the fish oil, and consolidate to one pharmacy so both the clash-checking and the Safety Net tracking happen in one place. Then ask her GP for a Home Medicines Review — free, and built for precisely her situation (Healthdirect, https://www.healthdirect.gov.au/home-medicines-review).

Now consider Frank, 74, comfortably self-funded, who takes four medicines and has stayed loyal to the original brands for years because "they've always worked." Money isn't tight, so he's never questioned it. On these facts Frank is likely paying a brand premium on top of each co-payment — and, crucially, that premium buys him nothing clinically and doesn't count towards his PBS Safety Net either (Pharmaceutical Benefits Scheme, https://www.pbs.gov.au/browse/brand-premium), so it's money that neither helps him now nor later. It is generally rational for someone in Frank's position to ask the pharmacist one question — whether a no-premium brand of the same medicine is available and suitable — and let the pharmacist and GP answer it. The saving is small per script and quietly substantial over a decade.

What if you're helping a parent?

The most useful thing you can do is the list. Sit down together, build the one-page version, and make sure it goes to the next GP appointment. Suggest the Home Medicines Review — most people have never heard of it. Ask the pharmacy about a dose aid if the routine looks hard. And then stop there: support the process, don't take over the medicines, and leave the clinical calls to the clinicians.

What should you do in short?

It's the pile, not the pill. Get every medicine you take — prescription, over-the-counter, supplement — onto one list you carry. Use one pharmacy so somebody sees the whole picture and your Safety Net tally stays in one place. Ask your GP for a free Home Medicines Review. Ask your pharmacist about generics and whether you're paying a brand premium that doesn't even count towards your Safety Net. And whatever you do, don't quietly adjust anything yourself, least of all because of what it costs — that's exactly the conversation your GP wants to have with you. An afternoon's organising here buys you a safety win and a money win from the same piece of paper.

Key takeaways

  • Taking five or more medicines is called polypharmacy, and 40% of Australians aged 75+ were dispensed more than five concurrent medications in 2022, well above the OECD average of 32%.
  • Medicines are a major falls risk factor because side effects like dizziness and unsteadiness compound as more are taken together.
  • Keeping one complete medicine list (including over-the-counter medicines and supplements) and using one pharmacy are free habits that let someone finally see the whole picture.
  • A free, GP-referred Home Medicines Review lets a credentialed pharmacist check everything you take at home and report back to your doctor, generally available every two years.
  • A brand premium for choosing a non-generic medicine does not count toward the PBS Safety Net threshold, so it's worth asking your pharmacist if a no-premium generic is suitable.

Frequently asked questions

What is polypharmacy?

Polypharmacy is the medical term for taking five or more medicines. It's common in older age — 40% of Australians aged 75 and over were dispensed more than five concurrent medications in 2022 — and the risk isn't usually any single medicine, but the fact that often nobody is looking at the whole list together.

How does taking multiple medications increase falls risk?

The more medicines you take, the higher the chance of interactions and side effects, and medicines can cause dizziness, unsteadiness, or changes to balance and coordination that raise your risk of falling. This is why medication review appears on nearly every falls-prevention checklist.

What is a Home Medicines Review?

It's a free, GP-referred service where a credentialed pharmacist visits you at home, reviews everything you take — prescription, over-the-counter, and supplements — and reports back to your doctor on anything worth adjusting. You can generally have one every two years.

Does a brand premium count toward the PBS Safety Net?

No. If you choose a branded medicine over an available generic and pay a brand premium, that extra amount does not count toward reaching your PBS Safety Net threshold. It's worth asking your pharmacist whether a suitable generic exists to avoid paying money that doesn't even help you reach cheaper scripts later in the year.
