UK Heatwave: Crucial Advice for Millions on Vital Medications
6 Jul
Summary
- Extreme heat can degrade active ingredients in essential medications.
- Some drugs increase susceptibility to dehydration and heatstroke.
- Millions in the UK need to protect medications from temperatures above 25C.
Millions of people in the UK are being advised on protecting their essential medications during extreme heat. The Medicines and Healthcare products Regulatory Agency (MHRA) issued guidance as temperatures recently peaked at 37.7C and are forecast to exceed 30C again this week.
Medicines, including commonly prescribed ACE inhibitors like ramipril and beta-blockers such as bisoprolol, typically require storage below 25C. Heat exposure can break down active ingredients, rendering them ineffective. Some medications can also make individuals more prone to overheating, dehydration, or sunburn.
Certain medications, such as those for diabetes, antipsychotics, and diuretics, carry heightened risks in hot weather. These can exacerbate dehydration or affect the body's ability to regulate temperature. The MHRA also notes that some antibiotics, antidepressants, and acne treatments can increase sun sensitivity.
Dehydration symptoms like dizziness and confusion are particularly dangerous for vulnerable groups. The MHRA urges individuals to move to cooler areas, sip water, and seek medical advice if unwell. Protecting medicines from heat in cars, bags, or sunny spots is essential for their efficacy and personal safety.
