"Out-of-pocket" cost refers to the payment made by the patient (either cash price or the copay amount). This value does not include reimbursement from a third party payer (eg, Medicare or private insurance) and does not represent the total drug cost.
In 2023, the average out-of-pocket cost for metformin stood at 4.68 U.S. dollars. Metformin is primarily used for the treatment of type 2 diabetes. This statistic shows the out-of-pocket costs of metformin prescriptions in the U.S. from 2004 to 2023.
