With temperatures rising across the UK, patients are being reminded that hot weather can affect medicines and medical devices.
Many medicines need to be stored below 25°C. Leaving medicines in hot cars, direct sunlight, warm rooms or bags during travel may reduce how well they work. This can affect tablets, inhalers, insulin, hormone patches and EpiPens.
If your medicine changes colour, smell or texture, please speak to your pharmacist before continuing to use it.
During periods of hot weather, it is also important to stay hydrated. Some medicines can increase the risk of dehydration, dizziness or overheating, particularly medicines used for blood pressure, heart conditions or diabetes.
Please seek medical advice if you feel unwell in the heat, especially if you experience dizziness, confusion, headaches or dark urine.
Some medicines may also make your skin more sensitive to sunlight and increase the risk of sunburn. Always read the patient information leaflet that comes with your medicine and take extra care outdoors during sunny weather.
To help keep medicines safe during hot weather:
• Store medicines in a cool, dry place away from direct sunlight
• Avoid leaving medicines in parked vehicles or warm bags
• Stay hydrated throughout the day
• Use sunscreen and stay covered if your medicine increases sun sensitivity
• Speak to your pharmacist or GP if you are unsure about your medication
Medical devices such as blood glucose monitors can also be affected by heat. Please check storage guidance carefully and keep devices in cool, dry conditions where possible.
If you have any concerns about your medicines during hot weather, please contact your pharmacist or the practice for advice.
