A London Pharmacy is in the spotlight for dispensing out of date medications (see article below), however this could equally apply to any retailer that sells OTC medicines.
Not only could dispensing out of dates be dangerous for the consumer, it also goes against the code of ethics from the Royal Pharmaceutical Society.
Out of date medications is not an uncommon problem for many pharmacies, and usually is a result where pharmacies or retailers fail to develop action plans to continually review their stock for outdated products.
Regular stocktakes by professional third parties such as Orridge can help reduce the levels of out of dates, however, only commitment by the pharmacy and retail team to a plan of regular action can help prevent them.
