Bring medicines due at the same time together instead of managing unrelated alarms.
Managing multiple medications
More medicines can mean a more demanding daily routine.
The challenge is not simply how many medicines appear on a list. Different times, doses, formulations, PRN limits and special directions can create a routine that is difficult to remember and accurately record—at any adult age.

A 2021 systematic review pooled eight heterogeneous studies. The 95% confidence interval was 34.0%–51.3%, and variation between studies was very high. This is not a prediction for an individual or a claim about MediMAR. Read the review →
Medication count
One study showed a clear discontinuation gradient.
In research involving people with atrial fibrillation, discontinuation of an anticoagulant increased across three total-medication groups:
31.8%0–4 medicines
35.4%5–9 medicines
42.4%10 or more
Important limitation
Read the systematic review →These figures concern anticoagulant discontinuation in an atrial-fibrillation study. They should not be presented as universal non-adherence rates for every medicine or person.
Across age groups
The association was not confined to older people.
A nationwide hypertension study compared people taking nine or more total medicines with those taking one to eight. Adjusted odds of non-adherence were higher overall and in several age groups:
Age 40–49+57%adjusted odds
Age 50–59+21%adjusted odds
Age 60–69+14%adjusted odds
These are relative differences in adjusted odds—not percentage-point increases and not a forecast for an individual. The study concerned adherence to antihypertensive medication in South Korea, so its results cannot automatically be generalised to every population or treatment.
Read the population study →What the evidence means
Count matters—but complexity matters too.
Research does not support a single universal threshold at which someone becomes non-adherent. Reviews have reported mixed associations between medicine count and adherence because the person, condition, medicine, measurement method and regimen all matter.
Six once-daily tablets may be easier to manage than three medicines with different times, variable doses and special instructions. A useful support tool therefore needs to organise the regimen rather than merely count products.
Polypharmacy is not automatically inappropriate
Read the multidrug-adherence review →Several medicines may all be clinically necessary. Decisions to start, stop, simplify or change treatment belong in a medication review with an appropriately qualified healthcare professional.
How MediMAR can help
Make a complicated routine easier to see and record.
Keep the intended quantity, time and entered directions beside each medicine.
Add an optional image of the current packaging as a visual prompt.
Support timing checks, entered PRN limits and cumulative paracetamol awareness across products.
Capture the outcome and actual administration time rather than assuming a reminder led to a dose.
Create a personal MAR or contextual report for your own review or a healthcare conversation.
Multiple medicines and personal support
Does taking more medicines automatically mean someone will miss doses?
No. Medicine count is only one factor. Timing, formulations, special instructions, side effects, beliefs, cost, health literacy and daily circumstances can all affect adherence.
Is polypharmacy only an issue for older people?
No. Polypharmacy is more common with age and multimorbidity, but adults of different ages can have complex regimens. One large hypertension study found an association between nine or more medicines and non-adherence across several working-age groups.
Can MediMAR tell me whether I take too many medicines?
No. Only an appropriately qualified healthcare professional can review whether each medicine remains necessary and suitable. Do not stop or change a medicine because of information on this page.
Can a MediMAR report support a medication review?
You can choose to share a personal record of entered medicines and recorded outcomes. It may support discussion, but it is not a verified clinical record and does not replace pharmacy or GP information.
