Medications and Heat
Some medications can increase the risk of heat-related illness. Medications can increase sensitivity to the heat or the sun, reduce thirst, impair sweating, and cause other effects that put people more at risk as the temperature rises. Heat can also degrade medications. Since individuals aged 65 and over and those with chronic illnesses are more likely to take medications, they are more likely to be impacted by these issues. Visit our Heat Preparedness – Extreme Heat web page for tips staying cool and safe on hot days.
It is important to review all your medications with your doctor, including over-the-counter medications, to see if any may put you at a higher risk of heat- or sun-related complications. Do not stop taking your medications without consulting your medical provider.
Some skincare products can make you more sensitive to the sun and increase your risk for skin cancer. Read the product labels and practice wearing sunscreen and other sun protection methods while using these products.
Proper storage of medication is an important consideration in the heat. Know what storage temperature is appropriate for the medications you take. If you are unsure, talk to your pharmacy for instructions.
