# These 10 Medications May Raise Your Risk of Heat-Related Illness
Certain common medications interfere with the body's ability to cool itself during hot weather, raising the risk of heat exhaustion and heatstroke. Understanding which drugs carry this risk helps people take protective steps during summer months or heat waves.
Anticholinergic medications pose the greatest threat. These drugs, prescribed for conditions ranging from overactive bladder to depression, block signals that trigger sweating. Without adequate perspiration, the body cannot shed excess heat effectively. Common anticholinergic medications include antihistamines like diphenhydramine (Benadryl), certain antidepressants, and urinary incontinence treatments.
Diuretics present another significant concern. These water-loss medications, commonly prescribed for high blood pressure and heart conditions, increase dehydration. Dehydration impairs the body's cooling systems and leaves people more vulnerable to heat illness.
Stimulant medications like those used for attention deficit hyperactivity disorder increase metabolism and body temperature regulation problems. Antipsychotics and mood stabilizers can also interfere with normal thermoregulation by affecting how the body responds to temperature changes.
Other medications that raise heat illness risk include certain asthma medications, topiramate (used for seizures and migraines), and some blood pressure drugs. Statins and nonsteroidal anti-inflammatory drugs (NSAIDs) taken regularly may also contribute to heat sensitivity.
People taking these medications should stay hydrated, avoid peak heat hours, wear light clothing, and monitor for heat illness symptoms including excessive thirst, dizziness, nausea, weakness, and rapid heartbeat. Checking with a pharmacist or doctor about individual medication risks proves valuable before summer heat arrives.
Those on heat-risk medications should never stop taking them without medical
