Certain medications, including SSRIs, diuretics, and ADHD treatments, can increase a person’s risk of heat stroke and dehydration during extreme heat, according to Leslie Herron, owner of Sumpter Pharmacy in Adel, Iowa. These drugs can impair the body’s ability to regulate internal temperature or accelerate water loss, making patients more susceptible to heat-related illnesses.
Why do SSRIs and ADHD medications increase heat risk?
Selective serotonin reuptake inhibitors (SSRIs), commonly used to treat anxiety, depression, and obsessive-compulsive disorder, can hinder the body’s natural cooling process. Herron explains that because these medications impact the same area of the brain responsible for temperature regulation, they can lower the ability to cool down, often leading to excessive sweating.
Medications for ADHD present a different but equally significant risk by potentially increasing a patient’s internal body temperature. Herron notes that patients often mistake these medication-induced symptoms for the general weather, stating, “In increased heat, you just think, well, it’s hot out.” This lack of awareness increases the likelihood of heat exhaustion or heat stroke.
How do diuretics affect hydration in high temperatures?
Diuretics, frequently prescribed for edema or hypertension, cause the body to lose water more rapidly. According to Herron, this acceleration of fluid loss significantly increases the risk of dehydration when temperatures rise.
While SSRIs affect the brain’s regulatory “thermostat,” diuretics act directly on fluid balance. This means a patient on diuretics may reach a state of dehydration faster than someone not taking the medication, even with similar water intake.
What happens to medication stored in heat and humidity?
Extreme heat doesn’t just affect the patient; it can degrade the chemistry of the drug itself. Herron warns that storing medications in high-heat or high-humidity environments—such as cars, purses, or bathrooms—can cause the drugs to break down and lose effectiveness over time.
To maintain potency, Herron recommends using a cool, dry storage area or an insulated bag. However, she cautions against placing medications in the refrigerator unless a medical professional specifically directs it.
Frequently Asked Questions
Can I stop my meds during a heatwave to avoid side effects?
No. According to Leslie Herron, medications like blood pressure pills and SSRIs should not be stopped abruptly. Consult your doctor first.
Where is the safest place to store medication during a heatwave?
A cool, dry place or an insulated bag is recommended. Avoid cars and bathrooms.
What are the signs that my medication is reacting to the heat?
While not always visible, medications stored in heat may become less effective. Check for changes in color or consistency and consult your pharmacist.
