Euthyrox
 

Posology and method of administration

Each patient has his own optimal thyroid hormone level. The dosage recommendations given in the following are therefore only a guideline for the therapy of the various thyroid diseases. Experience has shown that a lower levothyroxine sodium dose is sufficient to treat elderly patients and this also applies to low-weight patients or patients with a large nodular goiter. The important factor in determining the optimal individual thyroid hormone therapy is clinical observation of the patient and monitoring of the thyroid hormone parameters.

The daily doses can be given in a single administration.

Ingestion: as a single daily dose in the morning on an empty stomach, half an hour before breakfast, preferably with a little liquid.

Duration of treatment: usually for life in the case of hypothyroidism and after strumectomy or thyroidectomy; over a period of months or for life for the treatment of euthyroid goitre and for prevention of recurrent goitre; concomitant therapy for treatment of hyperthyroidism for the period in which the antithyroid drug is given.
