NDT – also referred to as desiccated thyroid extract (DTE) or "porcine thyroid" – is a thyroid hormone replacement medication in continuous use since the early 1900s. It was the first treatment for hypothyroidism and the only available treatment for the first half of the twentieth century.

How long does it take for NDT to work?

Available in multiple strengths for easy titration to achieve the necessary therapeutic range. Adequate therapy usually results in normal TSH and T4 levels after 2 to 3 weeks of therapy.

How long after eating can I take NDT?

YES: take it on an empty stomach. Wait 30-45 minutes (ideally an hour but who's counting the minutes) before eating and wait an hour after eating before taking it.
