Using Insulin, Inhalers or Antidepressants? Experts Share Urgent Warning

Hot weather can affect health in obvious ways, but it can also create a quieter risk for people who rely on daily medication. During a heatwave, the problem is not only the temperature outside. It is what heat can do to the body, to dehydration risk, and in some cases to the medicine itself.

UK medicine regulators have warned that some medicines can be affected if they are left in hot cars, bags, or direct sunlight, while others can make people more vulnerable to dehydration, dizziness, sun sensitivity, or overheating. The message is not to stop taking prescribed medicine. It is to store it correctly, understand the heat risks, and speak to a pharmacist or doctor if anything feels unusual.
