Hot Weather Warning: Your Medicines Could Fail
29 Jun
Summary
- High temperatures can render vital medications like insulin and EpiPens less effective.
- Asthma inhalers and diuretics may be impacted by heat-related pressure changes and dehydration.
- Antidepressants, antihistamines, antibiotics, and acne treatments pose risks in the heat.
With temperatures soaring, health experts are issuing an urgent warning to the public regarding medications that can be adversely affected by hot weather. Several common drugs require careful monitoring to ensure their efficacy and prevent dangerous side effects during periods of high heat.
Insulin, crucial for diabetics, can lose its effectiveness when exposed to high temperatures, failing to regulate blood sugar. Unopened insulin needs refrigeration between 2°C and 8°C, while opened vials should be kept between 15°C and 30°C. EpiPens, life-saving devices for severe allergic reactions, must be stored below 25°C, as excessive heat can reduce their reliability.
Asthma inhalers may also be impacted by heat due to internal pressure changes, affecting medication delivery accuracy. Diuretics, or 'water tablets,' can accelerate dehydration and hinder body temperature regulation. Antihistamines can reduce sweating, limiting the body's cooling capacity, while some antidepressants may impair the brain's temperature and sweat regulation, increasing overheating risks.
Furthermore, certain antibiotics can cause photosensitivity, making skin more prone to severe sunburn. Acne treatments, such as retinoids, can thin the skin, enhancing sensitivity to UV damage. Individuals are advised to check patient information leaflets for specific storage instructions, stay hydrated, use sunscreen, and consult a pharmacist if medication appearance changes.
