Medullary thyroid carcinoma (MTC)

What the FDA labels record as adverse events, each one tied back to the evidence it came from.

Definition

Medullary thyroid carcinoma, a rare tumor of thyroid C-cells. Every GLP-1 carries a boxed warning drawn from rodent data, and no increased human incidence has been demonstrated. Contraindicated with a personal or family history of MTC or MEN-2 — which is a question a legitimate intake form asks and a careless one does not.
