What Happens If You Overdose On Levothyroxine – Hypothyroidism means that a person’s thyroid gland does not make enough thyroid hormone. People with this condition may no longer have a functioning thyroid gland, or hypothyroidism may be caused by a number of other causes that affect the production of thyroid hormone.
Levothyroxine is also used to prevent or treat a goiter (an enlarged thyroid gland) or with other therapies to treat thyroid cancer.

® (levothyroxine sodium) tablets, for oral use is a prescription, man-made thyroid hormone used to treat a condition called hypothyroidism in adults and children, including infants. It is meant to replace a hormone normally made by your thyroid gland. Thyroid replacement therapy is usually taken for life. should not be used to treat non-cancerous growths or enlargement of the thyroid gland in patients with normal iodine levels, or in cases of temporary hypothyroidism caused by inflammation of the thyroid gland (thyroiditis). Levothyroxine (LT4) is used to treat endocrinopathy that often presents as thyroid disease. It is routinely used in cases of clinical (overt) hypothyroidism and cases of subclinical (congenital) hypothyroidism for the past decade. LT4 suppression therapy is also part of the medical regimen used to manage thyroid disease after a thyroidectomy. LT4 treatment has dual effects: it replaces new-onset thyroid hormone deficiency and suppresses local disease and distant spread of cancer. It is practical to administer LT4 in lower than high doses for the control of thyroid nodule growth and goiter, even in patients with preserved thyroid function. Despite the approved safety for clinical use, LT4 can sometimes induce side effects, more often recorded in patients under treatment with suppressive doses of LT4 than in patients with involuntary LT4 overdoses. Cardiac arrhythmias and worsening osteoporosis are the most documented side effects of LT4 treatment. It also lowers the threshold for the onset or worsening of cardiac arrhythmias in patients with pre-existing heart disease. To improve the quality of life in LT4-replaced patients, clinicians often prescribe higher doses of LT4 to reach the low-normal TSH level to achieve cellular euthyroidism. Under these circumstances, the risk of cardiac arrhythmias, particularly atrial fibrillation, increases, and the combined use of LT4 and triiodothyronine further complicates these risks. This review summarizes relevant available data related to LT4-suppressive therapy and the associated risk of cardiac arrhythmias.

Thyroidectomy is a surgical procedure, performed either as a normal open operation or as an operation of alternative approaches, such as video-assisted thyroidectomy (MIVAT) or robot-assisted transaxillary thyroidectomy, which aims to remove all or part of the thyroid gland (1 ). ). The procedure is often used to treat a number of thyroid-related diseases, including thyroid cancer, hyperthyroid goiter, and thyroid nodules that can be obstructive and cause difficulty swallowing or breathing (2). The introduction of MIVAT improved treatment options for certain thyroid conditions. Despite superiority in terms of patient satisfaction and faster recovery and reduced complications associated with standard open thyroidectomy (neck pain, voice problems, anxiety), it has been confirmed as a reliable procedure only in strictly indicated cases (1). It is not suitable for patients with hypothyroidism, large multinodular goiters, locally invasive thyroid carcinoma, or the presence of malignant lymph nodes in the lateral neck. It developed as a standard procedure in carefully selected cases of low-risk and intermediate-risk differentiated thyroid carcinoma (3, 4).
The thyroid gland produces iodinated thyroid hormones, triiodothyronine (T3) and thyroxine (T4) in response to thyroid-stimulating hormone (TSH) and the peptide hormone calcitonin, which is primarily regulated by serum calcium levels (5, 6). Together, these hormones regulate a wide range of metabolic and cardiovascular processes, including basal metabolic rate, appetite, intestinal motility, nutrient absorption, rate and force of heart contractions, respiration, and oxygen consumption (7). Thyroid hormones also play a role in development; they are essential for cell growth, while developing brain cells are a major target for T3 and T4 (8).
When the entire thyroid gland is removed, these gland operations are called total thyroidectomy. Knowing that thyroid hormones are essential for life, it is necessary to permanently replace the resulting deficiency with thyroxine after total thyroidectomy. Without replacement, a patient will develop signs and symptoms of hypothyroidism. The standard treatment in these cases is a long-term prescription of the synthetic thyroid hormone levothyroxine (LT4, a manufactured form of T4). In cancer, LT4 treatment
