With summer holidays in full swing and temperatures on the rise across the UK and popular travel destinations, the Medicines and Healthcare products Regulatory Agency (MHRA) is reminding the public about the critical importance of proper medicine storage. As part of its 'Summer-proof your health' campaign, the agency highlights that leaving medications exposed to heat, whether at home or while travelling, can significantly impact how well they work.
Many medicines are specifically designed to be stored below 25°C, and prolonged exposure to higher temperatures can render them less effective. This is particularly crucial for heat-sensitive medications such as insulin, certain types of inhalers, creams used for skin conditions, and some contraceptives. The MHRA also extends this advice to medical devices like blood glucose monitors and insulin strips, emphasising that their functionality can also be compromised by incorrect storage.
Dr Alison Cave, MHRA Chief Safety Officer, underscored the risks, stating, "During the summer, places such as parked cars, packed suitcases, caravans, and sunny rooms can get far hotter than people expect. For some medicines, these conditions can affect how well they work." She stressed that checking storage instructions, typically found on packaging or patient information leaflets, takes only a few minutes but is vital to ensure medicines remain safe and effective when needed.
The MHRA advises a few simple steps to safeguard medicines. Firstly, always consult the patient information leaflet for specific storage requirements, as some medicines need refrigeration while others require protection from light or heat. Secondly, avoid leaving medicines in vehicles, luggage, or other areas prone to extreme heat, especially during summer journeys. At home, medications should be stored in a cool, dry place, away from direct sunlight and heat sources like radiators or bathrooms, which can often be humid and warm.
Should individuals suspect that their medicine may have been exposed to excessive heat or is not working as it should, the MHRA recommends speaking to a pharmacist or doctor without delay. Suspected issues with medicines can also be reported directly to the MHRA via its Yellow Card scheme, contributing to broader public safety monitoring. This proactive approach ensures that any potential adverse effects from compromised medication can be addressed swiftly and effectively.
