First results and interim advice

The stock-out of Thyrax Duotab in the Netherlands forced thousands of Thyrax Duotab users to switch to other brands of levothyroxine.

The Dutch Society for Endocrinology (NVE) and the Dutch Thyroid Organisation (SON) initiated studies on the consequences of the stock-out of Thyrax Duotab in the Netherlands. These studies are conducted by the PHARMO Institute and the Netherlands Institute for Health Services Research (NIVEL).

The first results of these studies show to the effect of switching from Thyrax Duotab to other brands of levothyroxine on thyroid-stimulating hormone (TSH) values. The interim advice from the advisory board following these results can be found here (Dutch only).
