Summary
Thyroid hormones can increase sensitivity to catecholamines and may intensify the effects of tricyclics. This may lead to arrhythmias or CNS stimulation, particularly with excess thyroid dosing.
What this interaction means in plain words
Thyroid desiccated and Trimipramine 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.
Why it happens
Thyroid hormone increases adrenergic receptor sensitivity, adding to tricyclic-related cardiac and CNS effects.
What to do
Monitor heart rate, rhythm and mental state, and keep thyroid replacement at the lowest effective dose. Reassess if palpitations or agitation occur.
