Eli Lilly is very specific about NOT doing this. I suggest you contact 
them and ask. They are quite nice.  If it did not actually freeze, just 
got real cold, it is probably OK.  I think they are worried about the 
ingrediants separating if frozen or cold for a very long time and 
screwing up the potentcy.  I have a letter about it at work, I think it 
may be covered in the package insert.
