Dosage & Administration
Dosage.
For the treatment of each individual patient, depending on his individual needs, Euthyrox is available in tablets containing from 25 μg to 150 μg of levothyroxine sodium. Therefore, patients are usually prescribed only 1 tablet per day.
Dosage information is for guidance only.
The daily dose is determined individually, depending on laboratory parameters and the clinical picture of the disease.
Because an increase in T4 and fT4 concentrations has been observed in a number of patients on levothyroxine therapy, basal serum thyroid-stimulating hormone levels are a more reliable indicator for further dose adjustment.
Thyroid hormone therapy should be started at a low dose and gradually increased (every 2-4 weeks) to the required therapeutic dose.
Elderly patients with coronary heart disease, patients with severe or long-term hypothyroidism should be treated with extreme caution, with small doses (12.5 mcg per day), increasing the dose to maintenance at longer intervals (gradually by 12.5 mcg due to every 2 weeks), regularly monitoring the level of thyroid hormones. It should be borne in mind that the appointment of doses less than optimal, which provides a complete replacement therapy, does not lead to complete correction of TSH levels.
Experience has shown that lower doses are sufficient for patients with low body weight and for patients with large nodular goiter.
