However, if the dose is too high, symptoms of hyperthyroidism can occur. These may include increased heart rate, palpitations, nervousness, irritability, increased sweating, heat intolerance, weight loss, and changes in menstrual patterns [5]. If the dose is too low, symptoms of hypothyroidism may persist, such as fatigue, weight gain, constipation, feeling cold, and dry skin [5].

The dosage is individualized based on a patient's specific needs, thyroid hormone levels, and other health factors, and it is typically taken once daily on an empty stomach [6].
