Heat wave hazards

Certain medications can leave people more vulnerable to heat-related effects or the sun’s rays. The medications can raise the risk of dehydration, make people sweat too much or too little, impair the body’s ability to regulate temperature, or raise the risk of getting a bad sunburn. In addition, higher temperatures may damage some medicines, including diuretics, blood pressure drugs, some antidepressants, thyroid replacement hormones, and some over-the-counter antihistamines.
