When the summer temperatures rise, we tend to worry about sunburns and staying hydrated—but what about the medications we rely on? Hot temperatures can actually change how certain drugs work, making them less effective or even harmful. For older adults and people managing chronic conditions, these shifts aren’t just inconvenient – they can be serious, even life-threatening.
At Four Seasons Healthcare Solutions, we know how crucial it is to protect your health year-round. That’s why our Pharmacy Services are here to help you navigate medication safety in the summer heat. Here’s what you need to know.
Heat and medicine
Most medications, whether prescription or over-the-counter, are sensitive to temperature. Temperatures over 77°F (25°C), can cause pills to melt, capsules to stick together, and unseen chemical changes that make medications less effective or even harmful. Some medications like insulin, nitroglycerin, and thyroid drugs are more sensitive to temperature than others. Research finds that over 75% of individuals store at least one medication improperly. Because each drug has unique ingredients, different storage requirements may be needed, so it’s always good to ask your pharmacist how to keep medications safe.
Of course, vigilance is key. Watch out for these signs that the heat may have altered your medications:
- Changes in appearance. Pills that are discolored, melted, sticky, or crumbling are no longer safe to use.
- Unexplained symptoms. Worsening of chronic conditions (like high blood pressure or diabetes) may mean medications are no longer working as intended.
- New side effects. Heat can alter how medications are absorbed or processed, potentially increasing the risk of dizziness, dehydration, or heat intolerance.
If you notice any of these issues, don’t guess—call your pharmacist or your doctor.
Safe storage tips
Proper medication storage is essential, especially during the summer. Follow these general best practices to keep medicines safe:
- Store at recommended temperatures. Most medications should be kept between 68°F and 77°F (20–25°C) but check labels or with your pharmacist for specifics.
- Avoid storing medications in the bathroom. Humidity and temperature changes can compromise drug integrity.
- Never leave meds in a hot car. Interior car temperatures can soar to 120°F or higher in minutes – even with the windows cracked.
- Use a cooler with a cold pack (not ice) when transporting medications. Make sure drugs are not in direct contact with the pack to avoid freezing.
- Keep a thermometer in your storage area. This is especially useful in homes without central air conditioning.
- Ask your pharmacist if there is packaging to better resist heat and humidity. For example, blister packs or temperature-stable formulations may be available.
- Consult with Four Seasons Pharmacy Services. Our experienced pharmacists can recommend solutions and review whether your prescriptions are heat sensitive.
Medication management can be complicated, but you don’t have to do it alone. We’ll happily provide expert support to ensure your medications are stored, administered, and working properly, no matter the season. Whether you’re dealing with multiple prescriptions or just have a question about a new medication, we’re here to help keep you safe and healthy all summer long.
