With temperatures rising during the summer months, it’s easy to forget that medicines can be affected by the heat too. Many medicines are designed to be stored at room temperature (between 15°C and 25°C), and prolonged exposure to higher temperatures can affect their quality and effectiveness.
A common misconception is that storing medicines anywhere indoors is sufficient. In reality, places such as bathrooms, kitchens, conservatories and windowsills can experience significant temperature fluctuations, especially during a heatwave.
To help keep your medicines safe and effective, here are some simple dos and don’ts:
✅ DO
- Keep medicines in their original packaging whenever possible.
- Check expiry dates regularly.
- Follow any storage instructions on the label or packaging.
- Store medicines in a cool, dry place, away from direct sunlight.
- Take extra care with medicines stored in dosette boxes or monitored dosage systems, as these medicines have been removed from their original packaging.
- Ensure medicines requiring refrigeration are kept at the correct temperature.
- Keep medicines out of reach of children and pets.
❌ DON’T
- Store medicines in bathrooms, kitchens, conservatories, near radiators or on windowsills.
- Leave medicines in a hot car, even for a short period.
- Remove medicines from their original container unless advised to do so.
- Take medication that has not been prescribed for you.
- Use medicines that appear damaged or altered, including tablets or capsules that have changed colour, texture, smell, shape, or have become sticky, cracked or crumbly.
Remember, medicines are carefully manufactured to remain stable under specific conditions. Taking a few simple precautions during periods of hot weather can help ensure they continue to work as intended when you need them most.
If you’re ever unsure about how to store your medication, speak to your pharmacist for advice.
For medicines, just like people, staying cool in a heatwave is always a good idea.
