Thiamazole, also known as methimazole, is a medication used in the treatment of hyperthyroidism, a condition characterized by an overactive thyroid gland. Here is information on the indication and dosage of thiamazole:

Indication:

• Thiamazole is indicated for the treatment of hyperthyroidism in patients with Graves' disease or toxic multinodular goiter, for whom thyroidectomy or radioactive iodine therapy are not appropriate treatment options.
• It is also used to ameliorate hyperthyroid symptoms in preparation for thyroidectomy or radioactive iodine therapy.

Dosage:

• The dosage of thiamazole must be individualized for each patient based on their response to treatment and medical condition.
• Thiamazole is usually taken orally as a tablet, typically once or twice a day.
• The specific dosage and dosing frequency will be determined by the prescribing healthcare professional based on the patient's thyroid function tests and clinical response.
• It is important to take thiamazole exactly as prescribed and not to exceed the recommended dosage.
• Regular monitoring of thyroid function tests is necessary during thiamazole therapy to ensure appropriate management of hyperthyroidism.
• The duration of treatment with thiamazole will depend on the individual patient's condition and response to therapy.

It's important to note that thiamazole may cause side effects and interactions with other medications. Common side effects may include rash, itching, and gastrointestinal disturbances. Serious side effects such as agranulocytosis (a drop in white blood cell count) and hepatotoxicity (liver damage) are rare but can occur.

Please consult with a healthcare professional for personalized advice and guidance regarding the indication and dosage of thiamazole.
