Drug Information for Levothyroxine Sodium (Mylan Pharmaceuticals Inc.): WARNINGS

Ads
  • Levothyroxine sodium should not be used in the treatment of male or female infertility unless this condition is associated with hypothyroidism.

    In patients with nontoxic diffuse goiter or nodular thyroid disease, particularly the elderly or those with underlying cardiovascular disease, levothyroxine sodium therapy is contraindicated if the serum TSH level is already suppressed due to the risk of precipitating overt thyrotoxicosis (see CONTRAINDICATIONS). If the serum TSH level is not suppressed, levothyroxine should be used with caution in conjunction with careful monitoring of thyroid function for evidence of hyperthyroidism and clinical monitoring for potential associated adverse cardiovascular signs and symptoms of hyperthyroidism.
