Synthroid is a pharmacological analogue of thyroid gland hormones and has replaced hormones of the animal origin. In case of the deficit of thyroid hormones, a person has hypothyroidism.
Hypothyroidism is dangerous because the thyroid gland is increased because of the hormone deficit, and so it tries to produce more hormones. But new tissues do not produce hormones, so that complications happen.
Synthroid can make good the hormone deficit and reduce a load on the glandular tissue. Due to this, a development of hypothyroidism is prevented, and a tumor of the glandular tissue is reduced.
The drug may be used on any stage of hypothyroidism and even for the prophylaxis of the disease. Doctors have used hormones of the animal origin before but many people had side effects. Synthroid does not normally have side effects because it is an exact copy of the endogenic hormones of the thyroid gland.
It is medically proved that Synthroid should be used in the morning, after breakfast. This way, it is better digested and goes to the blood.
A level of the thyroid gland hormones is different at different age, and therefore a dose is individual. Moreover, the body weight, sex (women need more hormones), chronic diseases, a size of the thyroid tumor influence on a daily dose.
A standard scheme of the use of Synthroid is 1,7 mcg per 1 kg pf a body weight for adult patients over 12 years old and weighing more than 70 kg. If a patient weight 70 kg, a daily dose will be 119 mcg. But these are basic recommendations and a dose may be changed depending on a therapeutic effect during the treatment.
Children under 12 years old and weighing less than 70 kg should take more than 300 mcg per day.
The medicine is taken till the restored work of the thyroid gland and a disappearance of hypothyroidism symptoms.
- A decrease of the dose is recommended patients with cardiovascular diseases
- There are diseases when the use of Synthroid is contraindicated. For example, if a person has had myocardial infarction, or stroke, or chronic heart failure within the past 2 years, this medicine is not used
- Synthroid lowers the efficiency of the hypoglycemic products. The efficiency of the endogenic and exogenic insulin also drops. That is why, patients with pancreatic diabetes should adjust a dose of the medicines
- During pregnancy, the use of Synthroid will reduce a risk of the development of hypothyroidism in both a mother, and a baby. A dose should be reduced
An overdose with Synthroid causes an excessive increase of the thyroid gland hormone level. It is bad because the high level of the hormones may also harm the body.
If you are taking Synthroid and noticed such symptoms as increase of the heart rate, severe diarrhea, vomiting, excessive hair loss, putting on weight, go to a doctor and lower a daily dose. The further use of the drug in a standard dose may cause severe side effects.
If thyroid crisis developed, see a doctor as soon as possible.
