Euthyrox (levothyroxine) new formulation tablets: monitoring of patients switching between tablets

A Dear Healthcare Professional Letter has been issued by Merck to inform healthcare professionals on the new formulation of Euthyrox tablets. The re-formulated tablets will offer improved stability of the active substance throughout the medicinal product’s shelf life and do not contain lactose. How Euthyrox is taken and monitored remains unchanged. Close monitoring of patients switching to the new formulation of Euthyrox tablets is recommended as thyroid imbalances can be triggered by the switch due to levothyroxine’s narrow therapeutic range. Please refer to the letter for details.
