  • Indicated for treating hypothyroidism, euthyroid goiters, thyroid cancer, thyrotoxicosis, and myxedema coma.

Drug Interactions

  • Absorption can be decreased when taken with cholestyramine; should be taken 2 hours apart.
  • Dosing adjustments may be necessary for anticoagulants when taken concurrently.

Pharmacokinetics
