That makes the Thyroid Organization the Netherlands, who investigated the consequences of this move.

Especially patients per day more than 100 mcg of the active ingredient levothyroxine swallowing, have an increased risk of overdose. 53 percent of them sees the blood levels after the switch from normal to non-normal shift.

“That is big and can lead to health problems,” says prof. Fliers, endocrinologist and chairman of the consultative group that the studies guided. 30 percent of the patients experienced twelve weeks after the switch more complaints than before. A quarter of the patients had less complaints. The number of patients that (temporarily) ill had to report increased from 5 percent to 11 percent.

These results confirm the necessity of control of the blood six weeks after the switch. It is advised to patients who have a high dosage Thyrax (100 mcg or more) at a transition to a lower dosage.
