Pre-Mixed Insulin Therapy Guidelines
Initial Dosing Strategy
- The American Diabetes Association supports using commercially available pre-mixed insulins when the insulin ratio is appropriate to the patient's insulin requirements, with a starting dose of 10 units or 0.1-0.2 units/kg body weight per day, divided into two equal doses administered immediately before breakfast and dinner 1
- The American Diabetes Association guidelines recommend using pre-mixed insulins with a twice-daily regimen that targets both basal and prandial glucose control needs with a single product 2, 3, 4
Critical Pitfalls to Avoid
- Never mix insulin glargine with pre-mixed insulins due to low pH of its diluent, as recommended by the American Diabetes Association 2, 3, 4, 6
- If combining basal insulin with pre-mixed formulations, administer in separate injections, according to the American Diabetes Association guidelines 6
Dose Titration Protocol
- The American Diabetes Association recommends equipping patients with an algorithm for self-titration based on self-monitoring of blood glucose, with dose adjustments based on pre-meal and post-meal glucose readings 1, 5
Medication Adjustments
- Continue metformin when possible, and discontinue sulfonylureas and DPP-4 inhibitors when initiating this regimen, as recommended by the American Diabetes Association 1
- Meal timing becomes more critical with pre-mixed insulins compared to basal-bolus regimens, according to the American Diabetes Association guidelines 6
