Base information about Synthroid

Synthroid is a hormone of thyroid gland and produced in the laboratory conditions. This is a pharmacological analogue of the human hormone of the thyroid gland used for the treatment and/or prevention of hypothyroidism.

Unlike hormones of the thyroid gland of the animal origin, Synthroid is better tolerated and does not cause side effects, and it costs by several times cheaper.

The treatment of hypothyroidism consists in the reduction of the load to the thyroid gland. Using Synthroid compensates for the lack of hormones of the thyroid gland, so that the load is reduced, and tumor is gradually lowered.

Synthroid helps thyroid gland to work normally and does not use additional functional opportunities by means of the increased size.  The use of Synthroid will prevent a development of hypothyroidism and endocrine diseases which can appear because of the tumor of the thyroid gland.

Synthroid is used for the treatment of diffuse/nodal goiter of the thyroid gland in order to prevent the development of the chronic hypothyroidism.

Use and dose of Synthroid

The pills of Synthroid are taken orally with enough water. The pills should be used in the morning hours, this way it is better absorbed.

The daily dose of Synthroid depends on several factors: age, sex of a patient, concentration of hormones of the thyroid gland and size of the tumor. After complex medical examination, a doctor will prescribe a dose which will reduce the tumor.

Patients at the age of 12 to 50 years old with the body weight not more than 70 kg are recommended to begin the treatment of hypothyroidism with the minimal daily dose of Synthroid 1,7 mcg per 1 kg of the body weight. If a patient of this age group has the body weight more than 70 kg, it is recommended to take the maximal daily dose of Synthroid 300 mcg once.

Patients over 50 years old are prescribed a dose according to the scheme of 1 mcg of Synthroid per 1 kg of the body weight.

Recommendations for the use 

• Patients with cardiovascular diseases should take Synthroid in lower dose
• If a patient recently had myocardial infarction or has severe level of stenocardia or heart failure, the use of Synthroid is contraindicated
• Using hypoglycemic products during the use of Synthroid, their efficiency drops (including the efficiency of insulin). Patients with pancreatic diabetes should take this into account
• The use of Synthroid in high doses may cause a dysfunction of kidneys
• Synthroid is not contraindicated during pregnancy but the dose should be adjusted by a physician

Side effect

Using Synthroid, side effects appear because of the changed hormone level in the blood. This is a result of the adaptation to the drug action and the side effects usually last for 2-3 weeks.

Patients often experience pain in muscles and joints, fatigue, high appetite, high heartbeat, diarrhea, or severe hair loss during the use of Synthroid.

The intensity of the side effects is reduced and the treatment goes without unpleasant symptoms during the prolonged use of the drug.
