As temperatures soar above 30C across the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) has issued an urgent warning about the safe storage of medication during the heatwave. Households are being urged to never leave medicines in cars, bags, or on sunny windowsills, as excessive heat can cause them to lose effectiveness or become dangerous.
Expert Warning on Medication Storage
Alison Cave, Chief Safety Officer at the MHRA, emphasised the importance of proper storage during hot weather. She said: "Let's face it – when there's a heatwave, most of us are focused on getting outside and enjoying it while it lasts. But it's easy to forget that medicines left in the heat – in cars, bags, or on sunny windowsills – might not work properly when you need them." She added that neglecting this advice could lead to more serious consequences, including an increased risk of sunburn, dizziness, or dehydration, particularly for those taking diuretics or managing conditions like asthma, heart disease, or diabetes.
Key Safety Tips for the Heatwave
To stay safe, store medicines in a cool, dry place away from direct sunlight, especially when travelling. Recognise the signs of heat-related illness, such as dizziness, confusion, fainting, excessive sweating, rapid heartbeat, weakness, severe thirst, shakiness, and low blood sugar. Stay hydrated and listen to your body. If your medication increases sun sensitivity, take extra care by using sunscreen and seeking shade. Always read the patient leaflet and consult a healthcare professional if you have any concerns.
Pharmacist Advice on Heat-Sensitive Medications
Raj Rohilla, a pharmacist with over 35 years of experience, identified five groups of medicines particularly affected by heat: antidepressants, heart medications, diabetes drugs, diuretics, and asthma inhalers. He warned that these can degrade or cause adverse effects if exposed to high temperatures.
Warning Signs and When to Seek Help
The UK Health Security Agency (UKHSA) advises adults to act promptly if they notice dehydration or heatstroke symptoms, including dizziness, headaches, tiredness, confusion, or dark urine. This is especially critical for older adults, young children, and those with heart or kidney conditions. If you feel unwell in the heat, move to a cooler place, sip water slowly, and seek medical advice if symptoms persist. For medication-related concerns, visit your local pharmacy, but check opening times as some may have reduced hours during the bank holiday.
