Expiry date

An expiry date is the date beyond which a medicine should not be used under its specified storage conditions. Opening, preparing or compounding a product may create a shorter use period. The printed date is therefore not the only thing to check; storage instructions and the dispensing label also matter.

Can I use it if it looks normal?

Appearance is not a reliable test of safety or effectiveness. A product can change without an obvious difference in colour or smell. Do not assume that an unopened packet or a medicine kept for emergencies is still suitable without checking the dates and storage conditions.

Heat, moisture and unsuitable storage can affect a product before the printed expiry date. Tell a pharmacist if it has been left in a hot car, frozen unexpectedly or stored outside the recommended conditions. They can advise whether it should be replaced.

What changes after opening?

Some products have a specific discard period after opening or preparation. That period is not the same for every product, so follow the actual label rather than a general rule. Write the opening date on the container where appropriate and keep the original packaging.

Compounded preparations may have different storage and beyond-use instructions. Ask the supplying pharmacy to clarify any uncertainty. Do not transfer medicines into unlabelled containers or assume a date on an old box applies to a new supply.

How should I dispose of expired medicine?

Ask a local pharmacy about safe disposal of unwanted or expired medicines. Avoid flushing them or leaving them where children or pets can reach them. Keep an accurate list of current treatment so old supplies do not become confused with active prescriptions.

See Doccio's prescription information if a clinical review is needed before obtaining a new prescription. An expired product does not automatically justify a replacement without assessment, particularly when the underlying treatment plan has changed.

Where to go next

Read prescription consultations to understand the relevant service. A doctor decides whether a consultation, examination, referral or another pathway is appropriate for your situation.
