Summary: | The concentration levels of serum free thyroxine, serum free triiodothyronine, and thyroid-stimulating hormone were measured in 20 children receiving carbamazepine, 32 children receiving valproic acid, and 5 children receiving phenobarbital at the following times: (1) during chronic treatment, and (2) 3 months after the end of treatment with antiepileptic drugs. Patients during chronic treatment revealed significant changes in serum thyroid hormones, especially the children treated with carbamazepine and valproic acid. A number of children receiving long-term therapy with the two last antiepileptic drugs had varying grades of subclinical hypothyroidism. Three months after the end of treatment, a complete return to normal of all parameters was observed. These data demonstrate that the changes induced by these drugs are transient and reversible. |
