This medication is a thyroid hormone and is not appropriate for individuals with normal thyroid function to use for weight loss. Caution should be exercised, especially when taken with sympathomimetic amines, as serious toxicity may occur. Patients with specific heart diseases or thyroid disorders, such as acute myocardial infarction, acute myocarditis, severe angina, heart failure with tachycardia, and hyperthyroidism, should not take this medication. Patients with hypersensitivity to this drug or genetic issues such as lactose intolerance should also avoid it. Patients with hypertension, angina, pituitary insufficiency, diabetes, elderly individuals, and those with severe hypothyroidism should use this medication with caution, starting at a lower dosage and gradually increasing. In the event of overdose, various side effects such as palpitations, arrhythmias, insomnia, headache, vomiting, diarrhea, and flushing may occur, so if unusual symptoms appear, consult a doctor immediately. This drug may interact with various substances including coumarin anticoagulants, sympathomimetics, cardiac glycosides, hypoglycemic agents, and antacids, so it is essential to inform healthcare providers of any other medications being taken. Pregnant women can take this drug without stopping, although caution is necessary during breastfeeding. In treating children with hypothyroidism, it is important to adjust the dosage appropriately, and elderly patients should start with a small amount and gradually increase to reduce cardiovascular strain. Patients taking biotin should stop before thyroid function testing, as it may affect the results. In cases of overdose, appropriate emergency measures such as inducing vomiting, gastric lavage, oxygen supply, and administration of beta-blockers are necessary, and severe cases warrant immediate medical attention.
