Triple-digit temperatures are returning to Southern Arizona, and health officials in Pima County are warning residents that certain medications could quietly increase the risk of dangerous heat-related illnesses during the hottest months of the year.
The Pima County Health Department says nearly 50 commonly used medications may interfere with the body’s ability to regulate temperature and cool itself properly during extreme heat. Officials explained that some prescription drugs, over-the-counter medications, and other substances can change sweating patterns, lower blood pressure, increase dehydration risks, or affect the body’s awareness of heat exposure.
Health officials said medications linked to increased heat sensitivity include antidepressants, prescription painkillers, blood pressure medications, insomnia treatments, psychiatric medications, circulation-related drugs, stimulants, antihistamines, insulin, and some heart medications. Experts say these drugs can raise the likelihood of heat exhaustion, heat stroke, fainting, dehydration, and hospitalization when temperatures climb.
Betsy Camara with the Pima County Health Department’s Heat Relief and Response team said officials are increasingly noticing medication interactions in heat-related illness data collected throughout the county. She described medications as a “quiet culprit” that many residents may not realize can dramatically change how their bodies respond to extreme temperatures.
Camara said many residents have expressed surprise after learning their prescriptions could increase their vulnerability during Arizona summers. She explained that some people contacted the health department after realizing they or family members were taking medications associated with elevated heat risks.
According to Camara, the issue appears to be more widespread than health officials initially believed. She said the department now thinks medication-related heat risks may affect far more people throughout the community than originally expected.
As Southern Arizona enters another period of dangerous heat, the health department is expanding outreach efforts aimed at educating residents about the connection between medications and heat illness. Officials are encouraging people to speak directly with doctors or pharmacists about whether their prescriptions could increase sensitivity to heat and whether additional precautions are necessary.
The department emphasized that people taking heat-sensitive medications should pay especially close attention to hydration, time spent outdoors, and cooling strategies during the summer months. Health officials recommend staying indoors during peak afternoon heat, increasing water intake, limiting direct sun exposure, wearing light protective clothing, and visiting cooling centers if needed.
Public health experts also warned that extreme heat remains one of the deadliest weather-related hazards in Arizona and throughout the United States. Older adults, young children, pregnant individuals, people with chronic illnesses, outdoor workers, and those taking certain medications are considered among the highest-risk groups for heat-related illness.
The Pima County Health Department said community awareness is critical as temperatures continue rising. Officials hope residents will take the warnings seriously and review their medications before the hottest part of the summer arrives.
