Small dosages can exhibit anabolic effects on fat and protein metabolism. Medium doses cause stimulation of growth and development, metabolic processes, normalize the need for tissue oxygen, as well as the work of the heart, blood vessels and nervous system. The development of the therapeutic effect is manifested after 7-12 days, while maintaining stability during this time and after discontinuation of treatment.
Suction levothyroxine sodium occurs in the small intestine, directly in its upper section. Eating food has an effect on the absorption of the active substance, significantly reducing it. The maximum concentration of the component is reached after 5-6 hours from the time of use.

When hypothyroidism replacement therapy is performed, the dose is determined depending on the weight of the patients. When treating children under 3 years of age, the medicine is given before the first feeding, for half an hour. The tablet must be dissolved in water until a fine suspension is formed.

In case of an overdose of Eutiroks, a significant increase in the speed of metabolic processes is possible. This leads to development hyperthyroidism, and especially when exceeding the individual tolerance threshold levothyroxine sodiumas well as increasing the therapeutic dose too quickly.
In this case, overdose symptoms such as develop: arrhythmia, tachycardiaheart failure angina pectorismuscle and headache tremor, hyperemia, fever, vomiting, benign intracranial hypertension, anxiety, insomnia, hyperhidrosis, weight loss and so on.
The treatment depends on the symptoms. It is possible that the doctor will reduce the daily dose or recommend a break, prescribe beta blockers. As a result of taking excessively high doses, it is prescribed plasmapheresis. When the symptoms of an overdose are eliminated, the resumption of treatment is performed with caution, with the use of small doses.
Before starting thyroid hormone replacement therapy and a thyroid suppression test, you should rule out or treat diseases or abnormalities such as acute coronary insufficiency, angina pectoris, atherosclerosis, arterial hypertension, pituitary insufficiency or adrenal insufficiency.This also applies to the functional autonomy of the thyroid gland.
It is recommended to exclude the development of hyperthyroidism during treatment in patients suffering from coronary and heart failure, tachyarrhythmias. For this reason, it is necessary to regularly monitor the concentration of thyroid hormones.
If there is a suspicion of the occurrence of functional autonomy of the thyroid gland, then before treatment it is necessary to perform reactions to the introduction of thyroliberin, known as the TRH test, as well as suppressive scintigraphy.
Women during postmenopausal women diagnosed with hypothyroidism and increased risk osteoporosishigh physiological concentrations of the active component in the serum are not permissible. In this case, you need to regularly monitor the thyroid gland.

Combination with colestyramine, colestipol, aluminum hydroxide reduces the concentration of the active substance in the plasma due to inhibited absorption in the digestive tract. Therefore, between doses of these drugs, an interval of 4-5 hours must be maintained.
The simultaneous use of Eutirox and anabolic steroids, asparaginase, tamoxifen may lead to pharmacokinetic interaction at the level of communication with plasma proteins. It was also found that protease inhibitors, namely ritonavir, lopinavir and indinavirable to affect the effectiveness of this drug. It is necessary to control the concentration of thyroid hormones and carry out timely dosage adjustment.
Combination therapy with phenytoin often increases the concentration of sodium levothyroxine, accelerating its metabolism. This drug can reduce the effectiveness of hypoglycemic agents and enhance the effect of anticoagulants.
Application with sevelamer reduces the absorption of the active substance, and tyrosine kinase inhibitors, aluminum-containing, iron-containing drugs and calcium carbonate reduce its effectiveness.
