The impact of extreme heat goes beyond raising the danger of heat-related illnesses to threatening health by amplifying the side effects of many common medications. For instance, blood pressure pills that reduce fluid in the blood can lead to dehydration. Beta blockers for heart conditions can decrease blood flow to the skin, making individuals less aware of dangerous heat. Certain antidepressants can hinder the body’s ability to stay cool. Additionally, aspirin and other over-the-counter pain relievers decrease fluid and sodium levels, making it harder to cope with high temperatures. Combining the effects of heat and drug side effects could result in lightheadedness and falls.
Some medications like antibiotics, antifungals, and acne drugs can heighten sensitivity to the sun, leading to rashes and sunburns. It is essential for individuals taking these medications to wear sun-protective fabrics, apply sunscreen, or stay under an umbrella when exposed to sunlight. Failure to take these precautions could result in severe sunburns, as explained by Mike Ren, MD, a family physician at Baylor College of Medicine.
When traveling, medication should be kept in a cool, dry place unless it requires refrigeration. It can be challenging to maintain the required storage conditions while on the move. Before embarking on a summer road trip, individuals should check the storage requirements of their medications and carry them in a cooler, even if refrigeration is not needed. When traveling by plane, it is advisable to keep medications in a carry-on bag to prevent exposure to extreme temperatures in the cargo hold.
Mail-order pharmacies are responsible for ensuring that medications are stored at safe temperatures during storage and transit. However, there are instances where medications are not adequately protected from heat during delivery. In cases where individuals are unable to receive their mail-order medications promptly, the risk of exposure to extreme heat increases significantly. It is crucial to report any concerns about damaged medications due to heat to the pharmacy promptly to prevent further complications.
Despite the existing concerns about the impact of heat on medications, there is a lack of scientific evidence to support many of the common warnings. Researchers argue that behavior modifications, such as avoiding exposure to extreme heat, may be more effective than altering medications. As climate change accelerates, there is a growing need to identify which medications are the most vulnerable to heat-related damage. Renee Salas, MD, MS, MPH, an emergency room physician at Massachusetts General Hospital, stresses the importance of conducting further research to address this critical issue.
