Synthroid is a medication used in the treatment of thyroid gland pathology. It effectively restores thyroid function, normalizing patient condition and improving their quality of their life. In addition, Synthroid influences blood pressure, and is therefore often prescribed to patients with hypertension (high blood pressure).
Synthroid is produced from levothyroxine sodium. This substance is a synthetic analog of the thyroid hormone. The mechanism of effect is identical to that of thyroxin, influencing metabolic processes in all organs and systems of the body. Levothyroxine improves tissue growth, increases their need for oxygen, and stimulates fat, protein, and carbohydrate metabolism. In addition, Synthroid affects the nervous and cardiovascular systems, as well as systemic arterial pressure.
The purpose of using Synthroid is to compensate for the lack of hormones produced by the thyroid gland. In a number of cases (and for a variety of reasons), the thyroid gland does not cope with its secretory functions. This decrease in function has a negative effect on metabolic processes, with children being particularly disrupted in terms of their development (both mental and physical).
Synthroid is indicated for use in the following situations:
- treatment of benign processes in the thyroid gland;
- preventive treatment of relapses of euthyroid goiter;
- substitution treatment in the presence of hypothyroidism;
- suppressive treatment of thyroid cancers;
- an additional component of complex antithyroid treatment of hyperthyroidism;
- a diagnostic component in cases of thyroid suppression;
- therapy of diffuse toxic goiter.
Synthroid is used safely for treating the above-mentioned pathologies in children, as well as pregnant and breastfeeding women. A feature of the use of this drug in these periods in women is the requirement for particularly strict adherence to prescribed doses to prevent the development of hypothyroidism in the fetus or baby.
Synthroid is produced in tablet form in varying dosages: 25 mcg, 50 mcg, 75 mcg, 100 mcg, 125 mcg, 150 mcg etc. The dose depends on the type of pathology of the thyroid gland and the severity of the patient’s condition.
Taking the drug requires adherence to particular regimes:
- in the morning, on an empty stomach, between taking a pill and food, a minimum of half an hour should pass;
- dosage is selected so that one tablet per day is required;
- treatment, as a rule, is life-long (if no cancellation/replacement of the medicine is required), rather than a course.
Contraindications for use
Contraindications to the discharge and administration of Synthroid are:
- personal intolerance of any constituent medicine;
- adrenal insufficiency;
- pituitary insufficiency;
- acute period of myocardial infarction;
- myocarditis of acute course;
- during pregnancy, the drug cannot be used simultaneously with antithyroid medications.
With special caution, Synthroid should be used in cases of diabetes, high blood pressure (arterial hypertension), atherosclerosis, and various variants of coronary heart disease, including angina pectoris.
Overdose and weight loss
In cases of overdose, there may be a violation of the heart rhythm, increase in blood pressure, possible development of seizures and heart failure. Diarrhea, excessive sweating, and weight loss also develop. This condition is called thyrotoxic crisis. In such a situation, the dosage of Synthroid may decrease, or its administration ceases for several days. For correction of cardiac pathology, drugs from the pharmacological group of beta-adrenal receptor blockers are prescribed. In particularly severe cases, plasmapheresis is used.
Treatment with Synthroid typically produces few side effects, which are usually associated with allergies. The dosage is correctly determined by the doctor and is observed by the patient. Otherwise, the development of hyper- or hypothyroidism is possible.
Unauthorized cancellation will lead to hormonal deficiency; its most probable consequences are negative effects on metabolic processes. The drug can be canceled only by a doctor.
