Interaction report

Scopolia and Clomipramine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Scopolia interacts with whole categories of medication. Clomipramine falls into 2 of those categories, so it can interact with Scopolia in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

Major

ANTICHOLINERGIC DRUGS

1 of 2

Why this applies to Clomipramine

Clomipramine falls under ANTICHOLINERGIC DRUGS — the group Scopolia interacts with.

The alkaloid constituents of scopolia, including hyoscyamine, scopolamine, and atropine, could potentiate the effects and adverse effects of anticholinergic drugs.
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 about Clomipramine (Anafranil): on top of boosting serotonin, it already has its own anticholinergic activity, which is why people on it often deal with dry mouth, constipation, blurry vision, trouble urinating, and a fast heartbeat. Scopolia is packed with powerful anticholinergic alkaloids (atropine, hyoscyamine, scopolamine), so stacking the two means you're piling anticholinergic effect on top of anticholinergic effect.

That can turn those nuisance side effects into something more serious, things like real difficulty peeing, severe constipation, confusion, overheating, or a racing heart. This warning is based on how these substances work rather than firm human studies, but the concern is reasonable. Please don't change anything on your own. Check with your pharmacist or doctor before combining them.

TRICYCLIC ANTIDEPRESSANTS (TCAs)

2 of 2

Clomipramine also falls under TRICYCLIC ANTIDEPRESSANTS (TCAs).

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 about clomipramine (Anafranil): on its own, it already carries a fair bit of anticholinergic activity. That's why people on it often notice a dry mouth, blurry vision, constipation, trouble emptying the bladder, or a racing heartbeat. Scopolia is loaded with the same kind of acetylcholine-blocking compounds (atropine, hyoscyamine, scopolamine).

So when you stack the two together, you're essentially doubling up on that effect. The worry isn't that one cancels the other out, it's that the side effects pile on and get stronger, sometimes to the point of confusion, severe constipation, or an inability to urinate. This rating is based on how these drugs work rather than hard studies, but the logic is solid, so I'd treat it seriously. Please don't combine them without checking with your doctor or pharmacist first.

From our pharmacist’s overview on the Clomipramine page

“A tricyclic antidepressant used mostly for OCD, clomipramine (Anafranil) is unforgiving of shifts in its blood level, which is why its 236 supplement interactions deserve genuine wariness. Most of the list involves metabolism: herbs that speed up or slow down the liver enzymes handling clomipramine can drag its level too low or push it…”
