Summer Medication Tips: Keeping Your Prescriptions Safe in the Heat
Summer in Kitchener-Waterloo is wonderful — but the heat and humidity can be hard on your medications. Many prescription drugs are more temperature-sensitive than people realize, and improper storage can reduce their effectiveness or even make them unsafe.
Why Heat Affects Medications
Most medications are formulated to remain stable at room temperature — typically 15°C to 25°C (59°F to 77°F). When temperatures rise above this range, chemical reactions can occur, breaking down active ingredients and reducing effectiveness.
The Worst Places to Store Medications in Summer
- Your car — on a hot day, interior temperatures can reach 60°C or higher within minutes
- The bathroom medicine cabinet — heat and humidity from showers accelerate breakdown
- Near a window — direct sunlight degrades many medications
Medications That Are Especially Heat-Sensitive
- Insulin and other injectables — must be refrigerated or kept below 25°C
- Nitroglycerin (for heart conditions) — loses potency rapidly in heat
- EpiPens — should be kept between 15°C and 25°C; do not refrigerate
- Eye drops — many require refrigeration or protection from heat
Safe Summer Storage Tips
- Store medications in a cool, dry drawer or cabinet away from the kitchen and bathroom
- If travelling, use a small insulated bag to keep temperatures stable
- Check the storage instructions on every prescription label
