Missed doses are a systems problem
People who miss doses rarely forget that they take a medicine. They miss on the days that break the pattern — travelling, working late, being unwell, a change in childcare.
That is useful, because a system that only works on ordinary days is the wrong system. What you want is one that survives the unusual ones.
Anchor the dose to something you already do
A time of day is a weak anchor; an existing habit is a strong one. Brushing your teeth, making coffee, feeding a pet — these already happen reliably, and attaching the dose to one of them borrows that reliability.
Pick an anchor that happens in the same place each time, and store the medicine there, within the constraints of sensible storage. Cues work best when the thing is visible at the moment the habit fires.
Make a missed dose visible
The problem with taking a tablet from a bottle is that you cannot tell afterwards whether you did. A weekly organiser answers that question at a glance, which is why it helps more than its simplicity suggests.
Blister packs with the days printed on them do the same job. So does a note on your phone, if you actually mark it.
Plan for the days that break the pattern
Keep a small supply somewhere other than home — a bag, a desk, a coat pocket — where storage conditions allow. Set a reminder to reorder while you still have a week left, not on the day you run out.
If you travel across time zones, ask your pharmacist how to handle the shift before you go. For most medicines it is straightforward; for a few it needs thought.
Ask whether the regimen can be simpler
Before adding another alarm to a complicated schedule, ask whether the schedule itself can change. Some medicines are available in once-daily forms, some can be taken at the same time as others, and some may no longer be needed.
A periodic medication review with a pharmacist or prescriber is worth requesting, particularly if you take several medicines or have started something new recently.
