Résumé

Thyroid hormone may increase sensitivity to the effects of tricyclic antidepressants, and combined use has been associated with tachycardia and arrhythmias. Antidepressant response may also be accelerated, but toxicity may emerge more readily, particularly in patients with excess thyroid hormone.

Ce que signifie cette interaction, en termes simples

Amitriptyline and Levothyroxine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Amitriptyline belongs to Central Nervous System; Levothyroxine belongs to Endocrine.

Niveau de preuve: Low

Pourquoi elle survient

Thyroid hormone increases beta-adrenergic receptor sensitivity, adding to tricyclic noradrenergic and cardiac effects.

Conduite à tenir

Monitor heart rate, rhythm and thyroid function, and avoid over-replacement with levothyroxine. Watch for tricyclic toxicity and ECG changes in patients with cardiac disease.
