Time period within which a medicinal product may be used after the first opening. This time limit is necessary because microbiological stability may decline significantly after the first opening and the use-by period then ends before the expiry date. In the case of extemporaneous preparations, the date of manufacture and the first opening usually coincide or are close together. In all cases, the use-up periods are sufficiently long for the extemporaneous preparations.
