Medicine regulators in the UK are warning the public about the impact of heatwaves on medication usage.
Medicines left in hot conditions may not work properly and could increase the risk of sunburn, dizziness, or dehydration.
Recommendations include storing medicines in cool, dry places, staying hydrated, and being cautious in the sun if certain medications make the skin more sensitive.
The warning also extends to medical devices like blood glucose monitors, which may give unreliable readings if exposed to heat or humidity.
