Can i get reimbrsed from the insurance company?:
You might be able to.  Here's what I would do.

1.  Gather all your receipts.  If you don't have the actual receipts.. well.. your scewed and might as well stop here.  However, there is the possiblity that the old pharmacy has your perscriptions on file and they may be able to provide you with a print out of your purchases.
2.  I really don't think the Pharmacy will be willing to reimburse you.. but the insurance company might.  Copy all the receipts, write a letter and fill out your Insurance companies claim form.
3.  Send it all in and cross your fingers.

Good luck!
