The UK Health Security Agency (UKHSA) has issued rare red heat health warnings as temperatures are forecast to hit 40°C across parts of England. The warnings affect the West Midlands, East Midlands, South East, South West, London, and East of England. People who take regular medication, particularly statins, are being urged to store their pills correctly to prevent them from becoming ineffective.
Around seven to eight million adults in the UK take statins, making them among the most frequently prescribed drugs. Most medicines must be stored at temperatures below 25°C; otherwise, their active ingredients may deteriorate, leaving the tablets worthless. This can pose a serious risk for someone dependent on cholesterol-lowering medication, as it can result in undetected increases in low-density lipoprotein (LDL) cholesterol. If the medication loses its effectiveness, people could unknowingly face potentially fatal heart complications.
Where to Store Statins During the Heatwave
Statins must be kept away from the fridge due to the risk of moisture damage. Instead, those who depend on this medication need to seek out the coolest spots in their home to keep their pills effective. Avoid keeping pills on windowsills and bedside tables, as direct sunlight passing through glass creates a greenhouse effect, pushing the temperature of the medicine box well above the actual room temperature. Rooms prone to constant temperature fluctuations — such as the kitchen or bathroom — may spoil the medication due to humidity from showers or heat from cooking appliances like ovens, hobs, and air fryers.
It's best to opt for locations that don't experience dramatic temperature swings and can cope with the general heat. Drawers, wardrobes, cupboards and pantries are all ideal choices - particularly over the next few days. A low-level drawer in the bedroom or hallway could be a solid option, as cool air naturally settles closer to the floor. Spare space inside a wardrobe or storage cupboard also tends to stay cooler for longer, particularly if it doesn't share a wall with the exterior of the house. Storing your medication in a pantry or larder might seem a little unusual, but these dark, cool spaces, especially on the ground floor, typically maintain lower, more stable temperatures than the rest of the home. Ensure all medicines remain clearly labelled and well out of reach when children are around.
How to Tell if Statins Have Been Heat-Damaged
It is almost always impossible to tell if a statin tablet has been heat-damaged just by looking at it, as active ingredients can degrade without changing the tablet's appearance. Check for any crumbly, chalky texture or abnormal discolouration. Blister packs that have melted, warped, or become brittle are clear signs of excessive heat exposure. If you suspect your statins have been heat-damaged, do not take the risk and contact your pharmacist to confirm whether the medication is safe to use or if a replacement is needed.
