How to make sure you never run out of a medication before your next pill organizer fill
These are tips from my own experience as a caregiver – not medical advice. I'm not a healthcare professional. Always follow your pharmacist's or doctor's instructions for any medication.
Running out of a medication before it's time to fill the pill organizer is one of the most stressful things that can happen when you're managing multiple medications – whether for yourself or for someone else. It's also almost entirely preventable, if you catch it at the right moment.
I've been filling my mom's pill organizer for four years. She takes about 15 medications for MS, dementia, and other conditions. Early on I had a few close calls – moments where I realized mid-fill, or worse, mid-week, that a medication was about to run out. Over time I built a system that catches it consistently. Here's what's in it.
The right moment to notice is during filling the pill organizer – not before, not after
Most people notice a medication is running low either too early (weeks in advance, then forget) or too late (mid-fill, or when the organizer actually runs out). Neither is useful.
The right moment from my experience is during filling the pill organizer. You have the medication in your hand, you can see exactly how much is left, and you still have time to do something about it before the next fill. That's the window.
From my experience: as you work through each medication during the fill, check the box or bottle. If there won't be enough to cover the next fill, act on it immediately – don't make a mental note, don't rely on remembering later. Do something right then that guarantees you'll follow up.
The rubber band system
Before you start filling, group all boxes or bottles of the same medication together with a rubber band. When a rubber-banded group is nearly empty, you'll see it immediately as you pick it up. You don't have to count or estimate – a nearly empty group is visually obvious in a way that a single box isn't.
This sounds almost too simple, but from my experience it's one of the most reliable parts of the system. It turns "noticing" from something that requires active attention into something that's hard to miss.
Mark it immediately – then let something else do the remembering
When you notice a medication is running low during filling, the worst thing you can do is rely on your memory to follow up later. You're in the middle of a focused task. By the time you're done and the organizer is put away, the detail will be gone.
Mark it immediately. What you use to mark it matters less than the fact that you do it right then:
A phone reminder with a location trigger. I used to add a reminder to my phone's Reminders app – "restock Metformin" – with a time and a location trigger for whenever I was near the pharmacy. This works well and costs nothing.
The With app has a "Mark as running low" feature built directly into the fill flow. While you're going through each medication, you can mark it as running low right there. With then reminds you to restock before the next time you fill the pill organizer – a few days in advance, with enough time to make a pharmacy run. Once you've restocked, mark it as restocked and the reminders stop. It keeps the whole thing in one place instead of scattered across a reminder app and a medication list.
Stock further ahead than you think you need to
The deeper fix is upstream: if you consistently stock as much of each medication as you're able to get when you pick up prescriptions – three months where possible, less where that's all that's available – running low before it's time to fill the pill organizer becomes much less likely. You have a much larger buffer before anything becomes urgent.
This isn't always possible – some medications are only dispensed in monthly quantities, and some pharmacies won't fill early. But where it is possible, stocking further ahead is the single most effective way to reduce restock anxiety. From my experience, being able to see three months of a medication on the shelf is one of the few genuinely calming things about this whole process.
Keep a shareable list that includes restock status
If someone else ever needs to fill the organizer – a family member, a partner, anyone – they need to know not just what medications to fill, but which ones are running low and need a pharmacy run first. This information needs to live somewhere they can see it, not just in your head.
A shared document works. The With app keeps your full medication list including anything marked as running low in one place – accessible whenever you need it, and designed to be handed off when someone else is filling in.
What to do when you've already run out
It happens. Despite the best systems, occasionally a medication runs out before it's time to fill the pill organizer. A few things worth knowing:
Most pharmacies can do an emergency supply. If a medication runs out unexpectedly, ask your pharmacist about an emergency dispensing. Many pharmacies can provide a short supply to bridge the gap while you sort out the full prescription. This varies by medication and location – ask your pharmacist directly.
Don't skip doses without checking first. For some medications, missing a dose is relatively low risk. For others it isn't. If you're unsure, call the prescribing doctor or pharmacist before deciding to skip. Don't ask a friend or look it up online – your doctor and pharmacist are the only sources you should trust for this kind of question, and it's exactly what they're there for.
Use it as a signal to adjust the system. If a particular medication keeps running low, that's information. Either the stocking quantity needs to go up, the restock reminder needs to fire earlier, or something in the tracking system isn't catching it in time. Adjust accordingly.
