The tablets contain either 200 microgram (Forthyron® 200) or 400 microgram levothyroxine (Forthyron® 400). Both can easily be divided in four parts, which makes precise dosing possible.*
The recommended starting dosage is 10 microgram / kg body weight orally every 12 hour. Always keep the timing of treatment and its relation to feeding consistent from day to day, as the absorption of levothyroxine may be influenced by the presence of food.
In some case the dosage may require alterations before a complete clinical response is observed.
