been established.

[[Page 85]]

   ------------------------------------------------------------------
         Drugs with thyroid hormone activity, alone or together 
      with other therapeutic agents, have been used for the 
      treatment of obesity. In euthyroid patients, doses within 
      the range of daily hormonal requirements are ineffective for 
      weight reduction. Larger doses may produce serious or even 
      life-threatening manifestations of toxicity, particularly 
      when given in association with sympathomimetic amines such 
      as those used for their anorectic effects.
