Insulin Dosing Guidelines for First-Time Users
Recommended Basal Insulin Options
- The American Diabetes Association recommends long-acting basal insulins, such as insulin glargine (U-100 or U-300), detemir, degludec, or NPH insulin, for once-daily dosing 1, 3, 4
- Administer basal insulin at the same time every day, with morning administration recommended for simplicity and to reduce nocturnal hypoglycemia risk 1, 2, 3
Titration Protocol
- Monitor fasting finger-stick glucose values over one week, and increase the dose by 2 units if 50% of fasting values are above goal (90-150 mg/dL) 1, 2, 3
- Decrease the dose by 2 units if more than 2 fasting values per week are <80 mg/dL 1, 2, 3
- Reassess every 1-2 weeks until fasting glucose targets are achieved 1, 3
Critical Safety Considerations
- Avoid using rapid- or short-acting insulin at bedtime in first-time users or older adults to reduce nocturnal hypoglycemia risk 1, 2, 3
