What is the treatment of triiodothyronine toxicosis?
['Three patients met the criteria for free T3 toxicosis and three had subclinical hyperthyroidism. All six patients had either multinodular glands or a single nodule on thyroid exam. Four patients were treated with radioactive iodine or surgery, resulting in reversal of the TSH suppression in three cases.', '6 months treatment with propranolol (160 mg/day) in eight patients with T3 (triiodothyronine) toxicosis. Serum total T3 concentrations showed a significant (p less than 0.01) and sustained fall to approximately 80% of pre-treatment values.', 'Both patients responded to therapy with propylthiouracil.']
['Treatment of T3 toxicosis is a complex medical problem because not well responsive to the various options. Usual treatment includes antithyroid drugs such as propyltiouracil, radioactive iodine or beta blockers like propanol; surgery may be also necessary in some cases.']
