Insulin Aspart is an “authorized generic” provided by Novo Nordisk. It is literally Novolog that has been re-labeled. It is the exact same insulin as Novolog. This insulin is available for half the list price of Novolog.
Your pharmacy may have to order this insulin in advance. You may also have to explain to them that this is an authorized generic that you wish to purchase and not Novolog under its brand name. Certain pharmacies may not be able to order this for you based off of their distributors so it is important to check multiple pharmacies if needed.
A vial of Insulin Aspart is currently available for $71 at Walgreens with a GoodRx coupon.
