Health authorities have issued a cautionary advisory that crucial medications used by a large number of individuals in the UK may lose their effectiveness in the scorching 37C heatwave. Insulin pens, weight-loss injections, and asthma inhalers are examples of prescription drugs that must be stored at cool temperatures below 30C when not refrigerated. However, during hot weather periods, medicines left in bags, on windowsills, or in vehicles can heat up rapidly, potentially compromising their efficacy when used later.
Exposure to direct sunlight or high temperatures can significantly degrade insulin proteins, leading to reduced potency and elevated blood glucose levels in Type 1 Diabetics. Similarly, excessive heat can alter the chemical composition of asthma inhalers, rendering them ineffective during asthma attacks. Weight-loss medications like Wegovy and Mounjaro can also be compromised by prolonged heat exposure.
Alison Cave, Chief Safety Officer at the MHRA, emphasized the importance of safeguarding medications during heatwaves. She highlighted that medications left in hot environments may not function properly when needed. Some medications can also increase the risk of sunburn, dizziness, or dehydration, particularly for individuals taking diuretics or those with conditions like asthma, heart disease, or diabetes.
To combat these risks, it is crucial to store medications appropriately and seek advice from healthcare professionals if needed. The London Ambulance Service reported a record number of life-threatening emergencies due to the extreme heat, responding to a high volume of category one calls involving critical injuries and illnesses. Chief executive Jason Killens urged the public to take precautions, avoid excessive sun exposure, and stay hydrated to support emergency responders during challenging conditions.
