How often should you follow up on a patient with newly diagnosed hypothyroidism?

six to 8 weeks after the start of levothyroxine therapy you should reexamine patients and measure their serum thyroidstimulating hormone (TsH) (strength of recommendation [sor]: c, common practice and expert opinion). If thyroid function is normal at that time, examine the patient and measure serum TsH again in 4 to 6 months because clearance of levothyroxine increases in the euthyroid (normal) state (sor: c, expert opinion). once the proper maintenance dose of levothyroxine is achieved, evaluate the patient and obtain a serum TsH at least annually, or as clinically indicated (sor: c, expert opinion).
