What are the criteria for discontinuing propranolol in patients with hyperthyroidism?

Hyperthyroidism is the medical term for an overactive thyroid gland, and Propranolol usually refers to Propranolol Hydrochloride Tablets. Generally, the criterion for discontinuing Propranolol Hydrochloride Tablets in patients with hyperthyroidism is the absence of palpitations and a heart rate no greater than 70 beats per minute. The details are as follows:

Hyperthyroidism refers to thyrotoxicosis caused by excessive production of thyroid hormones by the thyroid gland itself, primarily manifesting as increased excitability of the nervous, cardiovascular, and digestive systems, along with heightened metabolism. Common symptoms include fatigue, excessive sweating, heat intolerance, weight loss, palpitations, and tachycardia. To manage cardiac symptoms such as palpitations and tachycardia, β-blockers are typically prescribed; Propranolol Hydrochloride Tablets are among the most commonly used medications. Medication may generally be discontinued when cardiac symptoms are under control, usually indicated by the disappearance of palpitations and a heart rate at or below 70 beats per minute.

It should be noted that patients often need to take additional medications such as Propylthiouracil Tablets or Methylthiouracil Tablets to control the underlying hyperthyroidism. Patients are advised to ensure adequate rest, maintain a light diet, engage in regular physical activity, all of which can support recovery.
