Should patients with hypothyroidism take Youjiale before their physical examination

Patients with hypothyroidism generally need to continue taking levothyroxine before the physical examination, but the specific medication time needs to be adjusted according to the type of physical examination items.

Youjiale is the main medication for thyroid hormone replacement therapy, and whether to take it before physical examination needs to consider two key factors. When fasting blood tests are performed to check thyroid function, it is recommended to take medication at least 4 hours after the blood test to avoid peak drug interference with TSH test results. If the physical examination includes an electrocardiogram (ECG) test, taking regular doses of levothyroxine will not affect ECG monitoring, but taking high doses may cause changes such as tachycardia. No special medication adjustment is required before conducting bone density testing. Long term thyroid hormone replacement therapy may affect bone metabolism, but a single dose does not affect the test results. Before conducting an iodine containing contrast agent examination, it is necessary to consult a doctor as there may be an interaction between Youjiale and the contrast agent. For examination items that require fasting for more than 8 hours, the medication time of Youjiale can be adjusted to be taken after the examination is completed. Patients with hypothyroidism should inform their doctors in advance of the medication and dosage they are taking, especially during thyroid related examinations. It is necessary to maintain a regular medication schedule in daily life and avoid increasing or decreasing the dosage on your own. On the day of the physical examination, medication can be carried as a backup, and it should be taken promptly after completing any items that require fasting. It is recommended to record the medication time for doctors' reference and regularly check thyroid function to adjust the medication plan. When experiencing discomfort symptoms such as palpitations and sweating, it is important to promptly communicate with the medical examiner.
