Prescribing thyroid hormone in any dose to patients presenting with symptoms mimicking hyperthyroidism does not improve the condition. For these individuals, beta-blockers can be prescribed to treat the increased sympathetic activation they experience. Beta-blockers are competitive inhibitors of adrenaline, the post-ganglionic neurotransmitter released by cells of the sympathetic nervous system. By blocking the ability of receptors to bind adrenaline, beta-blockers have been observed to alleviate symptoms of anxiety, increased blood pressure, and irregular heartbeat, amongst others. Anti-anxiety medications can also be prescribed to individuals with this conditions to treat symptoms of anxiety.
