Counting a pharmacy is harder than counting most shops, for three reasons. There are far more products, often well over a thousand lines in a small space. Many are tiny and expensive. And every one of them has a date after which it can't be sold.

In a provision store, a count asks "how many?" In a pharmacy it has to ask "how many, from which batch, expiring when?" That extra question changes how you set it up.

This guide is about the counting. It isn't regulatory advice. Follow your superintendent pharmacist and the current requirements of the Pharmacy Council of Nigeria and NAFDAC on storage, record-keeping and controlled medicines.

The count sheet

Rule one sheet per shelf or drawer.

Two things are different from an ordinary count sheet. Strength and pack matter, because 500mg tablets in a pack of 10 and the same medicine in a pack of 100 are separate stock lines. And each batch gets its own row, because two boxes of the same product can have expiry dates a year apart.

Decide your units before you start

Most pharmacy count errors are unit errors. One person counts boxes, another counts strips, a third counts loose tablets from an opened pack.

Pick a counting unit for each product and write it on the sheet. A workable rule for a community pharmacy:

  • Sealed packs are counted as packs.
  • An opened pack is counted in the unit you sell it by, usually strips or sachets, and recorded on its own line as "opened".
  • Liquids, creams and injectables are counted as bottles, tubes or ampoules.

Whatever you choose, keep it the same from one count to the next, and make sure it's the unit your stock record uses.

Counting, shelf by shelf

  1. Work in the order the stock is arranged. If your shelves run alphabetically or by therapeutic group, the sheets should follow the same order.
  2. Take everything off one shelf section, wipe it, and put the stock back as you count. Pharmacies collect loose strips at the back of shelves like nothing else.
  3. Group each product by batch and read the expiry date off the pack. Don't rely on the last sheet.
  4. Put stock back with the earliest expiry at the front, so it sells first.
  5. Write the count before moving on. Then mark the shelf as done.
  6. Leave the Book balance column until the section is finished, so the counter isn't guided by the expected figure.

You don't need to close for this. Count one bay a day in the quiet hours. If something is sold from a bay already counted, note it on a slip and subtract it before comparing. The general method is the same as in how to take stock in a shop without closing for the day.

The expiry list

The count is the best chance you get to find stock that's running out of time. As you go, keep a second sheet for anything expiring within the next six months.

Example tablets 500mg x 10A7712Feb 20274032,000Move to front, stop reordering

The figures above are placeholders to show the layout.

Then act on the list while there is still time to act:

  • Stop reordering the product until the old batch has gone.
  • Move it forward so it's the first pack anyone picks up.
  • Ask your wholesaler about their returns or exchange terms. Many will only consider stock with several months left, which is why six months is the right moment to ask and six weeks is too late.
  • Remove expired stock from the selling area straight away. Keep it apart, clearly labelled, and dispose of it the way your regulator requires. Record it as a loss with its cost value.

Run the expiry list every month, even in months when you don't count everything.

Items that need more than a monthly count

Some stock shouldn't wait for the regular cycle.

High-value lines, such as certain injectables and branded chronic medicines, are worth counting weekly. They are small, they are costly, and one missing pack can equal a day's profit.

Controlled medicines have their own legal rules on storage and registers. Keep to those, and reconcile the register against physical stock as often as the rules and your superintendent pharmacist require.

Cold-chain items should be counted quickly, with the fridge open as briefly as possible. Count them from the fridge's own list.

Reading the differences

When the count and the book disagree, pharmacies have a few causes of their own to rule out before thinking the worst:

  • a sale recorded against the wrong strength or pack size
  • strips sold from an opened pack and recorded as a whole pack, or the other way round
  • stock received and shelved before it was entered
  • samples or free goods from a supplier that were never recorded
  • expired stock thrown away without a record

If none of those explain it and the same products are short month after month, treat it as you would in any shop. How to stop staff stealing from your shop covers how to narrow it down fairly.

Afterwards, correct the book to the shelf with a dated line, and keep the sheets. A year of expiry lists will show you which products you keep over-buying, and that is where a pharmacy's stock losses are usually largest.
