Heat Wave Warning: Meds Can Affect Hydration
22 Aug
Summary
- Blood pressure meds can increase dehydration risk and blunt thirst signals.
- Store medications in a cool, dry place, avoiding humid bathrooms.
- Pharmacists are accessible resources for medication side effect questions.

As temperatures decrease following a recent heat wave, healthcare professionals emphasize continued vigilance regarding medication adherence and its interaction with heat.
Physician assistants highlight that individuals taking blood pressure medications should prioritize regular fluid intake. These medications can exacerbate dehydration and impair the body's ability to signal thirst, potentially leading to insufficient hydration. Patients are encouraged to carry water and drink consistently.
One patient shared his experience of developing kidney stones, which prompted him to consult his physician assistant. He learned his blood pressure medication played a role in his hydration levels, a side effect he had not previously considered. He now takes extra precautions, like shielding himself from the sun and ensuring he has hydration readily available when outdoors.
Pharmacists advise against storing medications in bathrooms due to humidity, recommending cool, dry locations instead. They also stress the importance of consulting with a pharmacist about medication side effects, noting their accessibility and role in patient counseling.
