Insulin degludec: the public record

Selected the most recently revised prescription label for this single ingredient from an original manufacturer, preferring a brand-name application. Checked which sections exist and quoted headings and sentences exactly as printed.

Scope: One label: the newest prescription label for single-ingredient insulin degludec from an original manufacturer

Read from one label. Labels for other brands, strengths or forms of the same ingredient can differ. A missing section heading does not mean there is no guidance. Read the full label before relying on it.

Summed total spending and claims over every brand and generic row with this generic name in the CMS file, using the Overall manufacturer rows. Combination products excluded. Average per claim is spending divided by claims.

Scope: Every single-ingredient insulin degludec product in Part D (Tresiba Flextouch U-200, Tresiba Flextouch U-100, Tresiba), 2024.

Gross drug cost before manufacturer rebates, so net cost is lower. Part D excludes some uses by law (for example erectile dysfunction, weight loss and hair growth), so claims reflect covered uses only. Compounded products are not included.

Matched each Medicaid product code to the FDA NDC Directory by labeler and product code, kept finished single-ingredient products, then summed prescriptions and reimbursement by state. National roll-up and suppressed rows dropped.

Scope: All single-ingredient insulin degludec products in the FDA NDC Directory, fee-for-service and managed care, 2025

Counts under 11 are suppressed by CMS and left out, so totals are a floor. Amounts are before rebates. Differences between states reflect programme size and coverage rules. Compounded products are not included.

Matched NADAC product codes to the FDA NDC Directory, kept finished single-ingredient products, and listed the product descriptions with the most package codes. The earlier price is the same package code in the file one year before.

Scope: Generic versions of insulin degludec in the weekly NADAC file of 2026-11-11, compared with the file of 2025-11-12

NADAC is the average invoice price retail pharmacies pay, from a voluntary survey. It leaves out rebates, dispensing fees and markups, and it is not what a patient or insurer pays. Compounded products are not surveyed.

Searched the ClinicalTrials.gov intervention field for the name, downloaded every matching record and counted by overall status and phase. Combined phases are counted under the higher phase. Phase not applicable covers observational, device and behavioural studies.

Scope: Studies whose intervention field matches insulin degludec, any condition, any country, all statuses

A registered study is not a result. Counts include studies where the drug is a comparator or background treatment, and studies that never finished or reported.
