Medicine lasts longest when it is kept cool, dry, dark and sealed, in its original labelled container, away from the heat swings of cars, attics and bathrooms. The few items that need a cold chain, mainly insulin, are the exception and need active cooling. Good storage slows decay but cannot restore strength already lost, so it should begin at the moment of salvage.
Part of Medicine Cabinet Raid
Storage is the one factor under your control after salvage, and it slows decay without reversing it.
Storage Is Slowing Decay, Not Stopping It
The four causes of decay (heat, moisture, light, oxygen) are explained in What Actually Degrades Medications. Storage is the practice of limiting each. It cannot turn back time, so how much it helps depends on the drug and on how it was kept before you found it. This guide makes no promise of a number of years.
The Four Habits
- Cool and steady. Avoid heat and swings in temperature. See Optimal Storage Conditions.
- Dry. Keep bottles closed and add desiccant. See Repackaging & Desiccants.
- Dark. Opaque containers, away from windows.
- Labelled. Keep the original container, so that you always know what a medicine is.
Method: Setting Up A Store
Step 1: Sort by fragility. Separate the cold-chain items (insulin, other biologics, some injectables) from sealed solids.
Step 2: Place the solids first. Put them in the coolest, driest, darkest place you have, off the floor.
Step 3: Give the fragile items their own cooling. See Optimal Storage Conditions.
Step 4: Record what you have. Name, strength, quantity, expiry date and condition when found.
Step 5: Inspect on a schedule. Look for crumbling, discolouration, smell, moisture and pests. Remove anything suspect.
Common Mistakes
- Using the bathroom cabinet. It is the worst place in the house.
- Moving everything into one jar. It destroys the labels.
- Storing and forgetting. Inspection catches the bottle that went wrong.
Safety
A medicine store is a poisoning risk
Children and animals can swallow what they find, and a mislabelled or mixed container can lead to a wrong drug being given. Keep medicine locked or out of reach, labelled clearly, and never store it near food or in food containers.
