EPI pen left in cold car overnight - is it ruined?

[Guest guest]

Crap! I am usually SO careful about the storage and transport of my son's EPI pen. But I accidentally left it in the car overnight last night and it was COLD out. Have I ruined the EPI pen? The EPI pen website says "refrigeration for extended periods may cause the unit to malfunction". Any advice?
