Why Do Some Medicines Say ‘Store in a Cool Place’ While Others Say ‘Refrigerate’?

Sounds similar, right? But they mean very different things—and ignoring them can make your medicine useless.

Let’s decode this in simple terms

You might have seen these two labels:

  • “Store in a cool place”
  • “Refrigerate between 2–8°C”

They’re not interchangeable!

  • “Cool place” = 8°C to 25°C

This means room temperature—but not in direct sunlight or near heat.

Common medicines:

  • Tablets
  • Capsules
  • Syrups
  • Creams

Don’t keep them in the fridge unless advised.

Too cold = moisture damage or chemical breakdown.

“Refrigerate” = 2°C to 8°C

These are temperature-sensitive drugs that need the cold chain maintained.

Common examples:

  • Insulin
  • Vaccines
  • Certain eye drops
  • Biologics

Always store in the middle shelf of the fridge—not the door, not the freezer.

Why does this matter?

Improper storage can lead to:

  • Loss of potency
  • Reduced effectiveness
  • Risk of adverse effects (especially injectables)

The medicine might look fine but won’t work properly.

Quick Tips

  • “Cool & dry place” = 8–25°C
  • “Refrigerate” = 2–8°C
  • “Do not freeze” = Seriously! Freezing can destroy many drugs

Always ask your pharmacist if you’re unsure!
