Starting Insulin in Type 2 Diabetes

Starting insulin in type 2 diabetes can feel intimidating—especially when you’re a new NP and you’re trying to figure out who actually needs insulin, how much to start, how to titrate it, and how to explain all of that to the patient without completely overwhelming them.

In this episode, I walk through the basics of initiating basal insulin in type 2 diabetes, including when insulin may be considered, how to calculate a starting dose, how fasting blood sugars guide titration, what to do when hypoglycemia occurs, and how to support patients as they learn a completely new skill.

Just as importantly, I talk about slowing the process down, using shared decision-making, and making sure patients understand what they’re doing and why.

2026 Update: This episode was originally recorded in 2020, and uses an older approach to type 2 diabetes treatment. The practical guidance on starting and titrating basal insulin, monitoring glucose, preventing hypoglycemia, and supporting patients through insulin initiation is still useful. However, current guidelines have changed when insulin is preferred, which medications are generally considered before insulin, and how treatment is intensified when basal insulin isn’t enough.

The Starting Insulin in Type 2 Diabetes Cheat Sheet is fully updated to include 2026 guidelines as included in the Digital NP Binder. For more comprehensive support with managing type 2 diabetes in primary care, including choosing and adjusting medications and insulin therapy, see the Diabetes Management in Primary Care course, updated in 2026.

What I Covered in This Episode:

  • When insulin may need to be considered in a patient with type 2 diabetes

  • How to start basal insulin, including fixed-dose and weight-based approaches

  • Using fasting blood glucose to guide basal insulin titration

  • How often insulin doses may need to be adjusted

  • What to do when a patient develops hypoglycemia

  • Why insulin initiation often requires close follow-up and patient education

  • How to use shared decision-making without overwhelming patients with everything at once

Key Takeaways

  • Basal insulin is usually the simplest place to start when insulin is being initiated in type 2 diabetes.

  • Starting insulin is only part of the job. Patients also need to know how to use it, how to monitor glucose, and what hypoglycemia looks like.

  • Fasting glucose helps guide basal insulin titration, but treatment goals should be individualized rather than using the same target for every patient.

  • Insulin initiation can be overwhelming. Breaking education and treatment changes into manageable steps can make it much easier for patients to follow through.

  • Close follow-up matters, particularly while the patient is learning insulin administration and the dose is being adjusted.

  • Shared decision-making is especially important in diabetes care because patients are the ones managing this condition every day.
