Scopolia and Amoxapine

Here is the interaction we found between these two, with the evidence behind it.

Major

TRICYCLIC ANTIDEPRESSANTS (TCAs)

Why this applies to Amoxapine

Amoxapine falls under TRICYCLIC ANTIDEPRESSANTS (TCAs) — the group Scopolia interacts with.

Concomitant use of TCAs with scopolia can increase the risk for anticholinergic effects and adverse effects.
Severity Major Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing Scopolia with amoxapine: they both pull in the same direction. Amoxapine, like other tricyclic antidepressants, already has its own built-in anticholinergic activity. Scopolia is loaded with potent anticholinergic alkaloids (atropine, hyoscyamine, scopolamine). Stack them and you can amplify those effects.

In real life that can mean a very dry mouth, blurry vision, constipation, trouble urinating, a racing heartbeat, confusion, or feeling overheated. In older folks especially, that combination can tip into dangerous territory. This concern is based on how these compounds work rather than hard studies, but the logic is solid and the risk is taken seriously. Please don't add Scopolia on your own; check with your pharmacist or doctor first.

From our pharmacist’s overview on the Amoxapine page

“Amoxapine (Asendin) is an older tricyclic antidepressant, and its supplement list deserves real care. Three of the 68 ingredients on file are rated major: activated charcoal can soak up the drug before your body gets it, lithium raises the risk of serotonin syndrome (a dangerous serotonin overload), and scopolia piles onto amoxapine's…”
