Medication and Fall Risk: The Overlooked Factor in Everyday Life
When an older person falls, relatives usually look for the cause in the room: a loose rug, a badly lit staircase, a cable in the way. That is sensible and worth doing. But it is only half the story. A considerable share of falls in later life has a cause you will never spot on a walk through the flat - it sits in the medicine cabinet.
This article explains why medicines can affect balance, which warning signs you can watch for, and how to bring the subject up without treating anyone like a child. First things first: this is not about talking medicines down, let alone leaving them out. It is about having them reviewed regularly, together with a doctor or pharmacist.
Why medicines can affect balance
Walking safely is a surprisingly complex achievement. The body constantly cross-checks information from the inner ear, the eyes, the joints and the muscles. The brain turns all of it into movement within fractions of a second. Dampen or slow down even one link in that chain, and walking becomes unsteady.
That is exactly where many medicines act - some by design, some as a side effect. They can cause tiredness, lengthen reaction times, let blood pressure drop on standing up, blur vision or shift the body's fluid balance. On its own, each of these effects is usually harmless. It becomes a problem when several come together.
And in later life, that is the normal case rather than the exception. Anyone living with several chronic conditions often takes several preparations at once - some prescribed by the family doctor, some by a specialist, perhaps plus an over-the-counter sleep aid or painkiller from the pharmacy. Nobody necessarily has the full picture. Professionals call this polypharmacy, and it is one reason why fall risk tends to rise with the number of preparations taken.
Which effects typically play a role
Without judging individual products - only the treating doctor or the pharmacist can and may do that - a few patterns of effect come up again and again in connection with falls:
- A dampening effect on the nervous system. Sleeping tablets and sedatives, some medicines for anxiety or depression, and strong painkillers can reduce attention and reaction speed. The hours around waking are particularly delicate, when the effect is still lingering and the night-time trip to the bathroom is due.
- A blood-pressure-lowering effect. Standing up quickly can make blood pressure drop too sharply for a moment. The result is dizziness or a brief blackout - often at exactly the moment someone gets up from a bed or an armchair.
- A draining, water-shedding effect. It increases the urge to urinate, which means more trips through a dark flat at night, and it can shift the balance of fluids and minerals in the body.
- Effects on blood sugar and eyesight. Low blood sugar makes people shaky and unfocused; some preparations can temporarily affect vision.
One point matters above all: every one of these medicines is prescribed for good reasons. Untreated high blood pressure or untreated depression carry substantial risks of their own. So the answer is never "stop taking it", but always "have it reviewed".
Why hot weather makes the effect stronger
In hot weeks, two things come together: the body loses more fluid through the skin, and many older people drink too little because the sense of thirst fades with age. The circulation is under pressure anyway. Add a medicine that lowers blood pressure or drains fluid, and the very same daily routine that worked without trouble in winter can suddenly produce moments of dizziness.
That is no reason to panic, but it is a good reason to have the medication discussed during the warm season - and to keep an eye on whether enough is being drunk.
Warning signs you can watch for
You do not need any medical knowledge to notice changes. In everyday life, look out for:
- dizziness or unsteadiness when standing up, especially in the morning or after an afternoon nap
- unusual daytime tiredness or difficulty finding words
- a new, cautious habit of holding on to furniture when crossing a room
- near-falls that get played down
- a pattern in the timing: the symptoms started shortly after a change to the medication
The last point is the most telling one. If someone's steadiness on their feet has changed within a few weeks of a new prescription, that is a very concrete clue to raise at the next appointment.
What families can actually do
- Draw up a complete list. Write down everything that is genuinely being taken: prescription medicines, over-the-counter products, vitamins, herbal remedies, drops, ointments. Simply putting every packet in a bag and taking it along works just as well.
- Arrange a medication review. The doctor's practice and the pharmacy can check the whole list for interactions and duplicate prescriptions. This is an established, routine step, not criticism of the doctors involved.
- Describe your observations precisely. "He gets dizzy sometimes" does not help much. "For about two weeks now, always about twenty minutes after the morning tablet, he has to steady himself on the door frame" is information someone can work with.
- Make taking medicines simpler. A weekly pill organiser, fixed times of day and a clearly readable list on the kitchen cupboard door cut down mistakes noticeably.
- Practise standing up slowly. Sit up first, stay seated for a moment, move the feet, and only then stand. This simple habit catches a lot of dizzy moments.
- Provide light at night. A motion sensor along the route to the bathroom offsets part of the risk that comes with fluid-draining medicines.
If something does happen
Even with the best preparation, not every fall can be prevented. What matters then is how quickly someone can call for help - and whether that still works when the phone is lying in another room.
That is exactly what NOA is made for. A mobile emergency button worn on the body starts a chain at the press of a button. First, the people closest to everyday life are alerted: family, neighbours, trusted contacts. If nobody from that circle responds, the 24/7 emergency call centre is brought in as a backup, so that nobody is left alone. The device also works away from home, which counts precisely when dizziness strikes on the way to the letterbox or while out shopping.
An emergency button is no substitute for a medication review. But it shortens the time between a fall and the first help arriving - and that time is what shapes the outcome.
