How to fill a pill organizer for multiple medications

Filling a pill organizer for one medication is straightforward. Filling it for someone who takes eight, ten, or twelve medications – different doses, different times of day, some only on certain days – is a different task entirely. It looks simple from the outside. It isn't.

I've been managing my mom's medications for four years. She has MS, dementia, and a rotating cast of other issues. For a long time I managed it with a Google Doc, a rubber band system, and about 45 minutes of focused concentration once a month. Over time I built a system that actually works – and eventually turned it into an iOS app called With that handles the parts that used to live in my head.

Here's what's in the system.

1. Start with a complete, written medication list

This is the foundation. Before anything else, you need a document – not a mental note, a real written list – that covers every medication: name, any alternative names (the same medication is often sold under different brand and generic names), dose, how many to take at once, which times of day, and which days of the week if it's not every day.

From my experience, this list saves you from the worst errors. It's also the thing that makes it possible for someone else to step in when you can't be there. Keep it somewhere shareable and up to date.

The With app stores this list for you and uses it to work out exactly how many of each medication to put in each slot – so you're not doing the math in your head every time you fill.

2. Group boxes of the same medication together with a rubber band

Before you start filling, take out all your medications and group every box or bottle of the same medication together with a rubber band. This does two things: it keeps things organized on the table, and – more importantly – when a rubber-banded group is nearly empty, you'll notice immediately. That's the right moment to mark it as running low – not when you're mid-fill and realize you don't have enough to finish, or worse, when the organizer runs out while taking medications.

3. Lay every medication out in a row before you start

Once your medications are rubber-banded by type, lay them all in a single row on the table in front of you. This is your working line. As you finish each medication, put it back in the bag. When the row is empty, you're done – and you'll know you haven't missed anything.

4. Go medication by medication, not day by day

Most people's instinct is to fill the organizer day by day – Monday morning, Monday noon, then Tuesday. From my experience, this is the wrong approach for multiple medications.

Go medication by medication instead. Pick up the first one, fill every slot it belongs in across all days and times, set it aside. Then pick up the next one. You're only thinking about one medication at a time – its dose, its timing, how many pills per slot. Context-switching between medications and days simultaneously is where errors happen.

5. Mark any medication that's running low – while you're filling, not after

As you work through your row, check what's left of each medication. If there won't be enough for next time, mark it as running low right then. Don't rely on remembering it later.

The With app has a "Mark as running low" feature for exactly this – mark it while you're filling, and With will remind you to restock before your next fill, with enough time to make a pharmacy run. Once you've restocked, mark it as restocked and the reminders stop.

6. Fill for more than one week at a time

Most advice says to fill weekly. From my experience, filling for two to four weeks at a time is significantly easier – you do it less often, you spend less total time on it, and you free up mental space. If you're filling for someone else and visiting once a month, filling four weeks at once means the job gets done properly on each visit.

The math gets more complex (how many pills for four weeks of a medication taken twice a day, six days a week?) but that's exactly the kind of calculation that should be handled by a list or an app, not done in your head. The With app works it out automatically – tell it how many weeks you're filling for, and it tells you exactly how much of each medication to put in.

7. Make the list shareable before you need to

The hardest version of this problem is the handoff – when someone else has to fill the organizer and everything that lives in your head suddenly needs to be written down clearly enough for someone who's never done it before.

From my experience: keep your medication list somewhere shareable and specific enough that someone else could follow it without calling you every five minutes. Include medication names and alternative names, doses, timing, and any notes that would otherwise only exist in your memory.
