28 days (one month) – this is the life of most* in-use insulin.

* Check your manufacturer’s information leaflet for your specific medication, noting that Novo Nordisk states 6 weeks for some brands but it is essential that you check the leaflet.

Please read the full explanation below: 

The FRIO® travel wallet is an evaporative cooling unit, purposely designed to keep in-use insulin cool within safe temperatures of 18-26°C (64.4-78.8°F) for 45 hours minimum, even in a constant environmental temperature of 37.8°C (100°F). The wallet can be ‘re-activated’/’topped-up’ to provide continuous safe storage conditions for subsequent periods of 45 hours minimum for up to 28 days (one month).

Note: 28 days (one month) is the life of in-use insulin. The wallet is re-useable.

Note: insulin must be at the manufacturer’s recommended temperature before being placed in the FRIO® wallet. Please check the manufacturer’s information leaflet for your specific medication.

For continuous safe storage, the FRIO® inner wallet should be re-immersed in water every 45 hours or sooner if the quantity of gel reduces and starts to return to its crystal form, i.e. crystals can be felt in the panels. When in continuous use, subsequent immersion periods will be shorter as the crystals will be continuously in gel form, i.e. 2-4 minutes will suffice (depending on the size of the wallet).
