We asked Stefania Atzori, the Lead Medicines Optimisation Pharmacy Technician for Shropshire Telford and Wrekin Integrated Care Board, to share her advice on managing medication during a heatwave.
She said, “these are the main points of advice we would always give people when it comes to medication”:
1. Always read the patient information leaflet provided with your medication
- Check the information leaflet for storage information, (medication, and devices, should be stored below 25°C).
- Heat damage can affect how much medicine your body absorbs, potentially making your usual dose too strong or too weak.
- If your medicine has changed colour, developed an unusual smell, changed texture, or looks different in any way, this could signal heat damage. Ask your pharmacist for advice.
- If you notice any changes in how you feel or how well your medicines are working during hot weather, speak to your pharmacist or doctor.
2. Drink more water and stay cool
- Diuretics, such as furosemide, increase fluid loss through urination, this can cause dehydration, so it’s particularly important for people taking this type of medication to be aware of the symptoms of dehydration, such as dizziness, headaches, tiredness, confusion, and dark urine.
- Blood pressure medicines such as ACE inhibitors, beta-blockers, or calcium channel blockers can make it harder for the body to regulate temperature. So, it’s important to stay hydrated and keep cool.
- Antipsychotic medications, such as olanzapine or quetiapine, or stimulant medications for attention disorders can increase body temperature, making you overheat more easily.
3. Check if your medicine increases your risk of sunburn
Some common medicines can make your skin much more likely to burn, even in mild sunshine. This includes some antibiotics, diuretics, antidepressants, or skin treatments for acne or eczema.
Additional advice:
If you’re travelling, avoid leaving your medication in parked vehicles or warm bags. A cool bag can help if you’re going to be out all day.
Keep devices and any test strips somewhere cool and dry and check the instructions that came with them for any temperature guidance. For example, blood glucose monitors may give people managing diabetes less reliable readings if used or stored in hot conditions.
