Store medicines correctly: temperature, humidity, light and rotation
Medicines stored badly can lose strength before their expiry date. Off-grid homes swing in temperature and humidity, so storage needs planning.
How
- Read every label for storage needs. Most medicines want a cool, dry place such as a drawer, closet shelf or kitchen cabinet away from the stove and sink.
- Do not store medicines in a damp bathroom cabinet: FDA says this can reduce effectiveness before the expiry date.
- Keep medicines in original labelled containers, out of direct sun and away from heat.
- Leave any desiccant packet or canister that came in the original bottle in place unless the label says otherwise; New Zealand's Medsafe notes some tablets rely on it against moisture. MedlinePlus advises removing the cotton ball from pill bottles because it draws in moisture.
- Put a min/max thermometer in the medicine cupboard and note readings in hot and cold seasons.
- Rotate stock: first in, first out. Mark the date opened on bottles and creams.
- After a fire, flood or overheating, follow FDA guidance: replace heat-exposed medicines, and discard medicines that touched flood or contaminated water, even if sealed. Lifesaving medicines with no replacement may be used only if they look unchanged, and replaced as soon as possible.
- Dispose of expired medicines through take-back schemes where available, or follow your local or FDA disposal instructions.
Safety: If a medicine has been stored outside its label conditions, ask a pharmacist or clinician whether it is still usable.
