Quick Summary
Thyroid-stimulating hormone (TSH), the pituitary glycoprotein hormone that tells the thyroid to make thyroxine. Its recombinant human form, thyrotropin alfa, has been FDA-approved as Thyrogen since 1998 for use in thyroid cancer follow-up. It is a human hormone, not a Russian bioregulator peptide, whatever the catalogue category says. Available from 2 vendors, priced from $93.00 to $221.08.
Research: Thyrogen's approved uses are narrow (Thyrogen US prescribing information, Genzyme, revised February 2023; BLA 020898). One is as an adjunct for serum thyroglobulin testing, with or without radioiodine imaging, in the follow-up of patients with well-differentiated thyroid cancer after thyroidectomy. The other is as an adjunct to radioiodine ablation of thyroid remnants after near-total or total thyroidectomy. The label describes no other use.
Side effects: From the Thyrogen prescribing information, the most common adverse reactions (over 5%) were nausea (11%) and headache (6%), transient flu-like symptoms, hypersensitivity and injection-site reactions are also listed
FDA-approvedThyrogen (thyrotropin alfa), Genzyme, initial US approval 1998, BLA 020898. A prescription product given by a clinician in one diagnostic and treatment setting; the vendor listings on this page are not Thyrogen.
