FIFO: The oldest stock, the first out

Let me explain with a simple image: imagine a well-organized medicine cabinet at a veterinary clinic. You open the door and see rows of bottles, syringes, bands, and vaccines. The goal isn’t just to store everything neatly; it’s to ensure the oldest items—those with the earliest dates—are used first. That’s the essence of FIFO, which stands for First In, First Out. The idea is straightforward: items that come in first should be the first ones to go out. It sounds obvious, but in a busy clinic, a sloppy system can turn a shelf full of good intentions into a pile of almost-expired products.

Why FIFO truly matters in veterinary pharmacology

Spoiler: safety, quality, and cost savings all line up when FIFO is in play. Perishable goods—medications with expiration dates, vaccines, and certain compounded formulations—don’t stay fresh forever. If you’re using an older bottle while a newer one sits behind it, you risk giving a med that’s less potent or, in the worst case, ineffective. Expired drugs aren’t just useless; they can be dangerous if they give false confidence to a treatment plan.

From a patient-care standpoint, FIFO helps ensure that every animal gets medications that are at their peak. That translates to better therapeutic outcomes and fewer adverse events tied to degraded products. For clinics and hospital pharmacies, FIFO reduces waste. When stock expires, it hits the bottom line and can cause shortages down the line. In short, a solid FIFO process protects patients, supports staff confidence, and keeps the business running smoothly.

Where you’ll see FIFO in veterinary settings

• Medications with shelf life: antibiotics, analgesics, anesthetics, and certain chronic disease meds. These aren’t like canned goods on a kitchen shelf; they’re medicine with real, time-bound potency.

• Vaccines: vaccines are particularly sensitive to time and temperature. Using the oldest available vials first helps avoid losing value to expiration.

• Compounded meds: when pharmacists prepare custom doses, the ingredients used have their own shelf lives. FIFO helps ensure the final product is still within its best-use window.

• Supplies with varying dates: syringes, saline bags, or dressings sometimes have different lot dates. Keeping them in date order minimizes waste and confusion during busy shifts.

How to implement FIFO without turning your workflow into a slog

No one wants to feel like a clock-watcher every time they reach for a bottle. Here’s how FIFO can fit into real clinic life without adding chaos:

1. Clear labeling and date visibility

• Label items with both received date and expiration date. A simple “first in, first out” cue (like a colored dot) can help staff spot the oldest stock at a glance.

• Consider a transparent bin or shelf for near-expiration items. You’ll see what’s coming up and can prioritize those items for use or discount rather than letting them linger.

2. Logical stocking and storage layout

• Group items by category but also by date. Put the oldest meds at the front and the newest behind them so the eyes go to the oldest first.

• Separate high-turnover items from slower movers if space is tight, but maintain the rule that the oldest stock is the first to go.

3. Routine checks that don’t feel like chores

• Do a quick daily sweep of shelves to ensure nothing is pushed to the back.

• Schedule a weekly mini-audit for expiration dates. It doesn’t need to be a long process—think 10 minutes with a quick checklist.

4. Use technology as a helper, not a boss

• Barcode scanning and shelf-life tracking software can automate alerts for items approaching expiration.

• A simple spreadsheet or an inventory app can remind you when stock is nearing its date, so you can rotate it properly or place urgent orders.

5. Assign ownership

• Designate a staff member (or a rotating role) to oversee stock rotation. Accountability helps a lot in busy clinics where people are juggling many tasks.

FIFO vs. other approaches: a quick, practical comparison

You might hear about Last In, First Out (LIFO) in some places. The idea there is the opposite: the most recently received items are used first. In veterinary medicine, LIFO can backfire because newer items aren’t necessarily the freshest in terms of potency or suitability for a particular patient. There’s also a more neutral approach—using items in a first-expired-first-out manner—common in many medical inventory systems. The point is simple: in the world of perishable medical supplies, mounting evidence favors keeping the oldest stock moving out first.

Common hurdles and light fixes

• Confusion over expiration dates: sometimes the dates aren’t clearly printed or are in different formats. Solution? Standardize date formats on all products and implement a quick reference card for staff.

• Overwhelming stockpiles in one area: solution—dedicate a “rotate zone” with clearly marked shelves and a rule that nothing newer blocks the older stock.

• Inconsistent inventory checks: solution—make checks part of a recurring routine, not a one-off task. Small, regular checks beat big, infrequent ones every time.

• Damaged packaging or compromised storage: solution—set up a quick triage workflow. If packaging is damaged or storage conditions are off, quarantine the item and document it.

A practical, real-life moment

Imagine a small animal clinic that keeps a combined inventory of vaccines, antibiotics, and topical creams. Every Friday afternoon, the team does a 15-minute rotation check. They pull out meds with the nearest expiration date, confirm the storage temp is within the recommended range, and adjust the shelf labels. A staff member notes any items that are now close to expiry and flags them for use first in the coming week. The result? Fewer expired products, faster retrieval, and calmer mornings because the stockroom isn’t a puzzle to solve.

Keeping things simple and effective

Here are a few bite-sized tips you can start applying tomorrow:

• Create a “front row” for items expiring this month and a “back row” for longer-dated stock.

• Use date-based color coding: red for near expiry, yellow for mid-term, green for safe-to-use.

• Keep a short, printable checklists near the stock area: verify date, confirm storage conditions, rotate stock.

• Train all team members on the same rotation rule so everyone follows the same pattern, every time.

Why it ultimately serves patients—and the people who care for them

When a clinic runs on a steady FIFO rhythm, there’s less risk of giving an older, degraded product. That matters because animals can be smaller, more fragile, or require precise dosing. Potency matters; potency isn’t a guessing game. Patients get the most effective care possible when medications are at their intended strength and when supplies are used before they degrade. For staff, it’s about confidence and consistency. You know what’s available, you know what to reach for, and you know you’ve done your due diligence to keep patients safe.

Closing thoughts: make FIFO part of the daily fabric

FIFO isn’t a flashy, techy gimmick. It’s a practical discipline, a daily habit that respects both science and compassion. It helps ensure that every vaccine you administer, every antibiotic you dispense, and every bandage you stock up on remains fit for purpose. The result is clearer workflows, less waste, and better outcomes for the animals in your care.

If you’re curious about how to tailor FIFO to your clinic’s layout or want a quick starter checklist you can print and pin near the stock area, I can help you draft one that fits your space and staff schedule. After all, a well-rotated shelf is a quiet, powerful advocate for safety, efficiency, and trust in veterinary care. And isn’t that what we’re aiming for: steady, thoughtful care that keeps tails wagging and patients thriving?
