What symptom is a client likely to exhibit if they have received too much levothyroxine?

When a client receives too much levothyroxine, a common symptom they are likely to experience is heat intolerance. Levothyroxine is a synthetic form of thyroid hormone, and when taken in excessive amounts, it can lead to hyperthyroid-like symptoms. One of the hallmark signs of hyperthyroidism is increased metabolism, which typically causes the body to have a heightened sensitivity to heat, leading to discomfort in warm environments and excessive sweating.

Individuals may find themselves feeling much warmer than usual and unable to tolerate temperatures that they would otherwise find acceptable. This stands in contrast to other potential symptoms associated with insufficient thyroid hormone, such as cold intolerance. Thus, heat intolerance reflects the effects of elevated thyroid hormone levels from an excessive dose of levothyroxine, indicating that the body is operating at an accelerated metabolic rate.
