Medications and Heat

Did you know hot weather can affect how your body responds to certain medications?

Some prescriptions can make it harder for your body to stay cool. This increases the risk of dehydration, dizziness, or even heat-related illness, especially if you’re spending time outdoors or don’t have access to air conditioning. Here are a few common types of medications that may raise your sensitivity to heat: 

Medications to Be Aware Of: 

• Diuretics – increase fluid loss and raise the risk of dehydration 

• Antidepressants and antipsychotics – may affect your ability to sweat and regulate temperature 

• Beta blockers – limit how your heart responds to heat stress, making it harder for your body to cool itself 

• Anticholinergics – reduce sweating and heat tolerance 

• Stimulants – can increase core body temperature 

What You Can Do: 

• Stay well-hydrated throughout the day 

• Avoid direct sun during peak heat hours  

• Wear light, breathable clothing to help your body cool down 

• Keep medications stored in a cool, dry place as directed 

• Talk to your pharmacist or provider if you have any questions about your medication
