Abstract

Medications can affect thyroid hormone production and function or interpretation of thyroid laboratory results. Awareness of these medication effects by  GPs allows for early detection of thyroid abnormalities, effective monitoring and prompt intervention when indicated.

Key Points

  • Medications can affect thyroid hormone production and function, or the interpretation of thyroid laboratory results.
  • Patients presenting with thyroid dysfunction should be asked about the use of medications, including over-the-counter preparations.
  • Thyroid stimulating hormone levels should be measured in all patients before starting a medication that may cause thyroid dysfunction.
  • Prompt investigation and appropriate treatment of medication-induced thyroid dysfunction is crucial to limit thyroid-related morbidity.
