Expiry date

The expiry date is the last date the manufacturer guarantees the product's quality in its unopened, correctly stored pack. Some fertility products also have a separate in-use period once opened or reconstituted — for example a multi-dose pen used over several days. Check both dates and ask your pharmacist if the pack is unclear.

Also known as: use by, shelf life, in-use expiry
