Thyroid: 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 thyroid 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.

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 thyroid 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 thyroid 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.

Counted enforcement report entries matched by FDA's listed active substance, or by the name in the product description where FDA lists none. Reasons were grouped by keywords in FDA's stated reason.

Scope: Recalls of single-ingredient thyroid products, plus compounded or unlisted products whose description names it

Each recall covers specific lots from one firm and is not a statement about every product with this ingredient. One event can appear as several entries, one per product.
