Choosing a Warehouse for Medicine

Start with the licence, not the price

Ask what the facility is licensed to store, and ask to see it. A warehouse approved for medical devices is not automatically approved for medicines. One approved for ambient pharmaceuticals is not necessarily approved for controlled drugs.

This sounds obvious. It is also the single most common reason a shipment sits at a port while somebody works out where it can legally go.

Ask to see last August

Any warehouse can hold temperature in February. The question is what happened during the worst week of the summer.

Ask for the temperature record from August. You are looking for two things: whether the zone stayed in range, and whether the excursions that did happen were noticed, investigated and written up. A record with no excursions at all is often a record with sensors in the coolest corner. A record showing three excursions, each with a note explaining the cause and the action taken, is a warehouse that is actually paying attention.

Ask when the mapping study was last done, too, and whether it covered summer and winter.

Test the traceability with a real question

Pick a batch number from your own stock and ask them to tell you how many units they hold, where they are and what the expiry is. Time it.

A warehouse running proper batch control will answer in a couple of minutes from a screen. One that needs to send somebody to walk the aisles with a clipboard has just told you what a recall would look like. Recalls are rare, but they are the moment when the difference between the two systems costs real money.

Find out what happens when something breaks

Chillers fail. Power drops. It is not a question of whether, only of what happens next.

• Is there backup power, and does it carry the refrigeration or just the lights?
• Who gets the alarm at 3am on a Friday, and how quickly do they get there?
• Is there somewhere to move chilled stock to while a unit is repaired?
• Will you be told, and how soon?

That last one matters more than people expect. Some operators tell you about an excursion after they have decided internally that the stock was fine. You want to be the one making that call about your own product.

Match the commercials to your actual pattern

Medicine stock rarely sits flat across a year. Tenders land, seasonal products spike, a registration comes through and volume triples.

If your volume moves, a fixed lease on a fixed footprint means paying for empty space for months at a time. Pallet-position or square-metre rental in a shared licensed facility flexes with you. If your volume is genuinely steady and large, a dedicated space may work out cheaper. Be honest about which you are, rather than which you expect to become.

What the building itself has to do

Procedures cannot rescue a building that is working against them. Before the operational questions, the structure has to be capable:

• Insulation and thermal mass. A shed that tracks the outside temperature will not hold a band through a UAE August, whatever the air conditioning is rated at.
• Redundant cooling. Plant that can be serviced without the room drifting out of range.
• Backup power sized for the cold rooms and actually tested under load, not merely installed.
• Sealed dock doors. The loading bay is the single largest source of heat and humidity ingress in most facilities.
• Pest control with documented inspection cycles.
• Racking that allows airflow, so cold air reaches the middle of a block rather than circulating around its edges.

Ask what the building does when the plant fails, not what it does when everything is working. The second answer is always reassuring and rarely useful.

Humidity, light and the conditions people forget

Temperature dominates the conversation because it is the easiest thing to measure. It is not the only condition that damages medicines.

Humidity matters for tablets, capsules, effervescent products and anything hygroscopic. In a coastal Gulf climate, uncontrolled humidity is a genuine risk, and a facility that monitors temperature alone is only watching half the problem.

Light degrades certain products, which is why they arrive in amber containers or opaque outer cartons. Stock stripped of its outer packaging for convenience loses that protection.

Ventilation prevents pockets of stagnant warm air forming in corners a sensor may not reach — one of the things a proper mapping study is designed to find.

Ask what is monitored besides temperature, and ask to see the humidity record alongside the thermal one.

Where medicines actually get damaged

In practice, loss rarely comes from a dramatic refrigeration failure. It comes from ordinary handling:

• Time on the dock. A pallet waiting in the open in July is out of its temperature range long before anyone records an excursion.
• Forklift damage to lower cartons, discovered later at picking.
• Over-stacking, which crushes cartons in the bottom layer.
• Mixed pallets built for shipping convenience, which make batch separation hard afterwards.
• Returns re-shelved without inspection.
• Repeated re-picking of the same carton, which wears packaging and obscures printed batch details.

A good facility has a damages log and will show it to you. An empty damages log is a warning sign rather than a boast — it usually means damage is not being recorded rather than that none occurs.
