What medications should you avoid if there is excess heat?

This summer, intense heat and high humidity are putting many people at risk, especially those who work outdoors. Prolonged sun exposure can lead to dehydration, heat exhaustion, and even heat stroke, a condition that causes more than 200 deaths in the United States each year. This data highlights the importance of not underestimating the effects of extreme heat.

Health professionals, like Dr. Holly Fanjoy, an emergency physician at Northern Light Eastern Maine Medical Center, warn of additional dangers for those taking certain medications. Diuretics, antidepressants, and other drugs can affect the body’s ability to sweat and regulate its temperature properly. Dr. Fanjoy explains that “such medications can make it difficult for patients to regulate their body temperature within the brain, as well as normal sweating mechanisms.” This can be a significant problem, especially for those with high blood pressure who rely on diuretics, as they may become dehydrated more easily.

Fanjoy points out that indications about the risks of these medications are not always clear on prescription bottle labels. “Many people don’t realize that the medications they are taking can have a significant impact on their ability to handle heat,” he added. Therefore, it is essential that patients speak with their doctors to fully understand the risks associated with their medications in extreme heat.

In general, doctors advise that most medications be stored in cool, dry places, and kept in their original packaging to avoid any deterioration that could affect their effectiveness.

For those who cannot avoid working under the scorching sun, several preventive measures are recommended. Wearing light, loose clothing, drinking plenty of fluids, and applying sunscreen regularly are essential practices. Additionally, it is crucial to watch for signs of overheating, such as dizziness, weakness, nausea, and excessive sweating. If these symptoms occur, you should act quickly by seeking shade, hydration, and medical attention if necessary.

Dr. Fanjoy stresses that avoiding direct heat, especially during peak times of the day, is vital for those who are at higher risk due to their medication or pre-existing health conditions. “It is essential to take these precautions seriously to prevent serious complications such as heat stroke,” she concluded.

This reminder is especially pertinent in a context of climate change and more frequent and intense heat waves. Staying informed and prepared can mean the difference between a safe and healthy summer season and a medical emergency.

The combination of extreme heat and certain medications can be dangerous. People should be aware of these risks and take proactive steps to protect their health. Staying hydrated, wearing appropriate clothing, using sunscreen, and avoiding direct sun whenever possible are actions that can prevent serious problems. Health and safety must be the priority during these hot days.
