The mechanism may be induction of hepatic CYP450 enzymes responsible for levothyroxine metabolism. Liothyronine may be similarly affected.

MANAGEMENT: Clinical monitoring of patient response, including laboratory serum TSH concentrations, is recommended. Adjustment of thyroid hormone dosage may be indicated when initiating or discontinuing rifampin therapy.
