^*Insulin product ‘units’ include multiple doses, as opposed to the oral hypoglycemic medications listed in the table, for which one unit is typically one dose. Therefore we do not provide unit costs.

Notes: Table indicates those drugs included in our sample, their average cost across VAMCs, and whether they are brand or generic. VA formulary agents are bolded (note: number of users may not add to total users by class, since patients may use more than one agent). Combination metformin/rosiglitazone and metformin/sitaglipitin are not listed above since they each had 5 users across the VA in FY08, although they are included in the sample.
