Thyroid natural extract, also known as desiccated thyroid, is a medication derived from animal thyroid glands. It is used to treat hypothyroidism (low thyroid hormone) and certain thyroid disorders. Here is information on the indication and dosage of thyroid natural extract:

Indication:

• Thyroid natural extract is indicated for the treatment of hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone.
• It may also be used to help decrease the size of enlarged thyroid glands (goiter) and to treat certain types of thyroid cancer.

Dosage:

• The dosage of thyroid natural extract is determined based on the indication and must be individualized according to patient response and laboratory findings.
• The usual starting dose of thyroid natural extract is 30 mg, with increments of 15 mg every 2 to 3 weeks.
• A lower starting dosage of 15 mg/day is recommended in patients with long-standing myxedema (severe hypothyroidism), particularly if cardiovascular impairment is suspected.
• The appearance of angina (chest pain) is an indication for a reduction in dosage.
• It's important to note that the dosage of thyroid natural extract should be determined by a healthcare professional based on the individual patient's needs and response to treatment.
