Lantus pen storage

I have just noticed the label on the front of my Lantus Solostar box says "pens in use must not be stored in the refridgerator". What the hell does this mean?

But why can't they be stored in the fridge once being used?. I've always kept them in the fridge used or not.

Done

Got a response from Sanofi

Storage of Lantus Solostar pens
Lantus SoloStar pens which have not yet been used should be stored in the refrigerator (between 2°C and 8°C) to maintain their storage life of 3 years.  They should be kept inside the box to protect them from light. Do not freeze them or keep them near the freezer compartment of the refrigerator. 
Before using your Lantus SoloStar pen that has been kept in the refrigerator, it should be left at room temperature (up to 25°C), for one to two hours. Once you have started using the SoloStar pen, it is advisable to leave it at room temperature as constantly removing the device from the refrigeration temperature to room temperature can affect the mechanics of the pen.
Once Lantus Solostar pens are removed from the fridge they can be kept and used for 28 days at a temperature up to 25°C.  Do not use Lantus if it has been kept for longer than 28 days out of the refrigerator or if the temperature has exceeded 25°C. 
I hope that the information is of interest to you. If you have any further enquiries regarding Lantus SoloStar then please contact us.

I just don't understand how something which needs to be refrigerated is put in a delivery device which can't cope with changes in temperature. Crazy :roll:
I always keep mine in he fridge and the only time it comes out is for 10 seconds twice daily when I inject. I wonder if these guidelines are intended for hospital use. Never had a solostar pen fail because of its mechanics before.

I often wonder how people in hot climate go on when they don't have access to a fridge. My friend(whom is type 1 himself) is a pharmacist in Australia and tell me the Aboriginals keep there insulin out in the bush with no ill effects. Makes me think its all about cover the pharmaceutical industry covering its back against litigation.
