Nobody plans to take eight medicines. It happens one prescription at a time. A blood pressure tablet at 55. A statin a year later. Something for reflux, something for sleep, a painkiller for the knee, a supplement a friend recommended. Each made sense when it started. Together they're a lot to keep track of, and nobody may have looked at the whole list in years.
That situation has a name: polypharmacy. This guide explains what it means, why it matters, and how to ask for the review that keeps it safe.
What polypharmacy means
Polypharmacy simply means taking several medicines at the same time. There isn't one universal cut-off, and it isn't automatically a problem. Many people genuinely need several medicines, and each one is doing an important job.
The concern is that as the number goes up, so do the risks, and some medicines on a long list may no longer be needed, may overlap, or may be treating the side effect of another.
Why many medicines raise the risk
MedlinePlus puts it simply: the more medicines you take, the higher the chance of interactions or side effects. The main risks are:
- Interactions. Two medicines, or a medicine and a supplement, can affect each other. The FDA's examples include St John's wort making several prescription medicines less effective, and ginkgo biloba, aspirin or vitamin E adding to bleeding risk alongside warfarin.
- Side effects that look like new problems. Dizziness, tiredness or confusion can be put down to age or illness, and treated with yet another medicine, when they're actually caused by one already on the list.
- Duplicates. Two prescribers, two brand names, the same medicine. Or a prescription plus an over-the-counter product containing the same ingredient.
- Mistakes in the routine. MedlinePlus notes it can be hard to keep track of when to take each medicine, or to remember which you've already taken.
Step 1: Build one complete list
Everything starts with an accurate list. Most people's list is incomplete, and the missing items are exactly the ones that cause interactions: supplements, herbal remedies, over-the-counter painkillers, creams, eye drops, inhalers.
For each item, record the name as printed on the label, the instruction in the prescriber's words, what it's for, who prescribed it and which pharmacy fills it. The "what it's for" column is the one that reveals duplicates and medicines nobody can explain anymore.
Our guide to a medication reminder for multiple medications covers organising a long list by prescription, which makes it much easier to see what belongs to what.
Step 2: Ask for a medication review
A medication review is a structured look at everything you take, with a pharmacist or doctor, to check that each medicine is still needed, still working and still safe alongside the others.
How to ask for one:
- Ask directly. "Could we go through all my medicines together? I'm taking quite a few now." Pharmacists and GPs are used to this request.
- Bring everything. The actual bottles and boxes, not just the list, including supplements and over-the-counter products. Some pharmacies call this a "brown bag" review.
- Say what's bothering you. Side effects, doses you find hard to keep, medicines you're not sure you still need, costs.
- Ask good questions. What is each one for? Is it still needed? Could any be combined or taken at the same time as others? What should I watch for?
MedlinePlus suggests going over your list with your provider at each appointment and asking whether you still need everything on it. Ask your doctor or pharmacist how often a full review makes sense for you, and ask again whenever something changes: a hospital stay, a new diagnosis, a new specialist, or a new symptom.
Deprescribing is the prescriber's decision
You may come across the word "deprescribing". The NHS Specialist Pharmacy Service describes it as tapering, stopping or withdrawing medicines that are no longer appropriate, beneficial or wanted, through shared decision-making with the patient and follow-up support. It's a real and increasingly common part of good care.
It's also something that has to be done by the prescriber, not by you. Some medicines are dangerous to stop suddenly, and the NHS, for example, warns against stopping antidepressants suddenly or without talking to your doctor, and advises talking to a doctor or pharmacist before stopping statins. Your job is to raise the question. Theirs is to decide, and to plan how.
Step 3: Make the routine manageable
Even after a review, a long list needs a system:
- Consolidate dose times where your pharmacist agrees it's safe. Two dose times are much easier than five.
- Anchor doses to meals and routines, following any food instructions on the labels.
- Use an organizer so you can see at a glance what's been taken. The pill organizer planner lays it out.
- Keep refills in step. With many medicines, they run out on different days. The refill date calculator works out each reorder date.
Doz groups medications by prescription, so each prescription becomes one card holding every medication it contains, with the prescriber and how long the course runs. Meal-timed doses follow your real mealtimes, and Doz tracks stock and sends refill reminders while you still have pills left. It does not check for interactions; that's what the review with your pharmacist is for.
Step 4: Keep the list current
A review is only as good as the list after it. Update your list the same day anything changes, and carry a copy. If you end up in an emergency department, the first question will be what you take.
Frequently Asked Questions
What is polypharmacy?
Polypharmacy means taking several medicines at the same time. It isn't necessarily a problem, since many people need several medicines, but the more you take, the higher the chance of interactions and side effects, so regular reviews matter.
How do I ask for a medication review?
Ask your pharmacist or doctor directly, and bring every medicine you take, including supplements and over-the-counter products. Ask what each one is for and whether it's still needed. Ask them how often a review makes sense for you.
Can I stop some of my medications myself?
No. Talk to your prescriber first. Some medicines need to be reduced gradually, and stopping others can raise health risks. Deprescribing is a planned process your prescriber leads.
Does Doz check for drug interactions?
No. Doz reminds you to take your medicines, groups them by prescription and tracks refills, but it does not check for interactions. Ask your pharmacist to review your full list for that.
Where to start
Gather every medicine, supplement and cream you use into one bag this week, and book a review with your pharmacist or doctor. Once the list is settled, Doz can hold it on your iPhone, grouped by prescription, with reminders that sound through Silent mode and refill warnings before anything runs out.
