Patient's Query

I’ll be traveling through very hot areas with limited refrigeration options. I've heard of using cooling pouches or even clay pots to store insulin. Are these methods effective and reliable for keeping insulin safe?

Yes, proper insulin storage is crucial, as heat exposure can degrade insulin, reducing its effectiveness.

Reliable methods include:

Cooling pouches: Products like FRIO use evaporation and can safely maintain insulin temperatures for many hours without refrigeration.
Clay pots (earthen pots): Traditional evaporative cooling can keep insulin cool in hot climates. Keep pots damp and shaded to maintain stable temperatures.

Also, remember:

Avoid direct sunlight and enclosed spaces like parked cars.
Most insulin types can remain stable at room temperature (below 30°C/86°F) for up to 28 days after opening.
Regularly check insulin appearance—discard if cloudy or discolored.

Consult product guidelines or a healthcare provider for brand-specific recommendations.
