Exposure limits and toxicity
Occupational exposure limits and toxicity data
The signs and symptoms of levothyroxine overdosage are those of hyperthyroidism. In addition, confusion and disorientation may occur. Cerebral embolism, shock, coma, and death have been reported. Studies indicate that careful attention is necessary when initiating the administration of levothyroxine sodium to very-low-birth-weight infants. Ingestion of levothyroxine in children typically follows a benign course, but overdose can result in significant complications, including seizures and arrhythmias, both of which should be monitored for. In one genotoxicity study, the ability of thyroxine to induce sister chromatid exchange and micronuclei was tested in cultured human lymphocytes.
