Finding the Right Doctor for Insulin Degludec

If you've been told you need Insulin Degludec — sold under the brand name Tresiba — or you're looking to switch from another basal insulin, you'll need a prescriber who's familiar with it. The good news is that several types of doctors can write this prescription, and finding one near you is easier than you might think.

This guide walks you through exactly how to find a provider, what to expect at your visit, and how to make the process as smooth as possible.

What Type of Doctor Prescribes Insulin Degludec?

Insulin Degludec (Tresiba) is an ultra-long-acting basal insulin used for type 1 diabetes (adults and children age 1+) and type 2 diabetes (adults). Several types of healthcare providers can prescribe it:

• Endocrinologists — Diabetes specialists who manage complex insulin regimens. If you have type 1 diabetes or hard-to-control type 2, this is often your best bet.
• Internal Medicine doctors — Many internists manage type 2 diabetes and are comfortable prescribing basal insulins like Tresiba.
• Family Medicine doctors — Your primary care physician can prescribe Insulin Degludec, especially for straightforward type 2 diabetes.
• Pediatricians — For children with type 1 diabetes, a pediatrician or pediatric endocrinologist can prescribe Tresiba.
• Nurse Practitioners and Physician Assistants — In most states, NPs and PAs with prescriptive authority can also prescribe insulin.

In short, you don't necessarily need a specialist. But if your diabetes is complex or you're switching from another insulin, an endocrinologist may be the best starting point.

How to Find a Provider Near You

1. Use Your Insurance Directory

The fastest way to find an in-network doctor is through your insurance company's provider directory. Most insurers let you search online by specialty (look for "endocrinology" or "internal medicine") and location. This ensures you won't get surprise out-of-network bills.

2. Search on Zocdoc or Healthgrades

Platforms like Zocdoc, Healthgrades, and Vitals let you search for doctors by specialty, insurance accepted, and location. You can often book an appointment online the same day. Filter for endocrinologists or primary care doctors who treat diabetes.

3. Ask for a Referral

If you already have a primary care doctor, ask them for a referral to an endocrinologist. Some insurance plans (especially HMOs) require a referral before you can see a specialist. Your PCP can also start you on Insulin Degludec themselves if they're comfortable managing it.

4. Consider Telehealth

Many telehealth platforms — including Teladoc, MDLive, and others — can prescribe insulin for established diabetes patients. This can be a great option if:

• You live in a rural area with limited specialists
• You need a prescription quickly
• You're already diagnosed and just need a medication adjustment

Telehealth visits are often faster to schedule and may cost less than in-person appointments.

5. Check Academic Medical Centers

If you're near a university hospital, their endocrinology department will almost certainly have doctors experienced with Tresiba. These centers often have the latest treatment protocols and may also help you access savings programs.

What to Expect at Your Appointment

Whether you're seeing a new doctor or asking your current one about Insulin Degludec, here's what to prepare:

• Bring your diabetes history — Current medications, recent A1C results, blood glucose logs, and any previous insulin regimens.
• Know your insurance details — Some plans require step therapy (trying Insulin Glargine first) or prior authorization before covering Tresiba. Your doctor's office can help with this, but it speeds things up to know your plan's requirements.
• Ask about dosing — For type 2 diabetes, the typical starting dose is 10 units once daily. For type 1, it's usually about one-third to one-half of your total daily insulin dose. Your doctor will individualize this.
• Discuss cost — Tresiba's cash price runs $300–$500 per box of FlexTouch pens. Ask about the Novo Nordisk savings programs that can bring your cost down to as little as $0–$35/month.

After You Get Your Prescription

Once your doctor writes your Insulin Degludec prescription, you'll need to fill it. Here are a few tips:

• Check stock first — Tresiba has experienced intermittent supply issues in 2025–2026. Use Medfinder to check pharmacy stock before making a trip.
• Ask about prior authorization — If your insurer requires it, your doctor's office will usually handle the paperwork. It can take a few days, so plan ahead.
• Know your injection technique — Tresiba FlexTouch pens are injected subcutaneously in the thigh, upper arm, or abdomen. Your doctor or a diabetes educator should walk you through proper technique.

Final Thoughts

Finding a doctor who can prescribe Insulin Degludec doesn't have to be complicated. Start with your primary care doctor or insurance directory, consider telehealth if access is limited, and come prepared with your diabetes history and insurance information.
