The OTC insulins included are the older generation of insulin (R, N, 70/30 Mix, 75/25 Mix.) These are available without a prescription for as low as $25 for a 10 ml vial. Some Charitable Pharmacies have been able to work with suppliers to purchase OTC insulins in a limited quantity for patients.
The OTC insulins have a dissimilar action profile than prescribed insulins. However, as shown in the CINCI study, the different profile does not indicate a lower quality.
Though a prescription may not be required, ensure providers know what insulin their patients are using. Patients converting from a basal/bolus regimen to the older insulins require education as to insulin timing, mixing and storage.
