Summary
Estrogens may raise tricyclic concentrations and adverse effects in some patients, while the antidepressant response may also vary. The evidence is limited and the effect is inconsistent.
What this interaction means in plain words
Estradiol and Nortriptyline have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Estradiol belongs to Endocrine; Nortriptyline belongs to Central Nervous System.
Why it happens
Estrogens may inhibit tricyclic hepatic metabolism, though the mechanism is not well established.
What to do
Watch for anticholinergic effects, sedation or orthostasis, and for loss of antidepressant response, when estrogen therapy is started or stopped. Adjust the nortriptyline dose according to response.
