TAKING MEDICATION THIS SUMMER? WHAT YOU NEED TO KNOW ABOUT SUN AND HEAT EXPOSURE

The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a public health advisory for the summer months, warning that certain prescription and over‑the‑counter medicines can increase sensitivity to sunlight and raise the risk of dehydration. The advisory, released by News and communications, calls for patients to review medication labels and seek medical advice before exposing themselves to high temperatures. It applies to the UK population and comes ahead of the peak summer heatwave period. The agency urges individuals to adopt protective measures such as wearing sunscreen, hats, and staying hydrated. The message is intended to prevent heat‑related complications linked to drug‑induced photosensitivity.

According to the advisory, the MHRA identified a range of drugs—although specific names are not listed—that can heighten photosensitivity or impair the body's ability to regulate fluid balance. The agency has encouraged patients to discuss any concerns with their healthcare providers and to read drug information leaflets carefully. No specific statistics were released in the brief, but the warning is part of broader public health efforts to reduce heat‑related illness during the summer. The statement underscores the importance of medication awareness when planning outdoor activities.

Photosensitivity reactions can lead to sunburn or skin damage, while impaired fluid regulation increases dehydration risk, both of which are heightened during hot weather. This advisory follows previous MHRA guidance on medication safety during seasonal temperature changes.
