Interaction report

Goldenseal and Atomoxetine

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

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Why this applies to Atomoxetine

Atomoxetine falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Goldenseal interacts with.

Goldenseal might increase serum levels of drugs metabolized by CYP2D6.
Clinical and in vitro research shows that goldenseal can significantly inhibit CYP2D6 enzymes, potentially increasing levels of drugs metabolized by CYP2D6.
Severity Moderate Likelihood Probable Evidence B

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 goldenseal with Strattera (atomoxetine). Your body relies heavily on an enzyme called CYP2D6 to clear atomoxetine out. Goldenseal appears to slow that enzyme down, and atomoxetine is the active drug itself (not a prodrug that needs switching on). So blocking CYP2D6 tends to let the medication build up higher than expected.

In real life, that could mean more of atomoxetine's usual side effects: a faster heartbeat, higher blood pressure, dry mouth, trouble sleeping, decreased appetite, or feeling jittery. The evidence here is moderate, not airtight, but it's worth taking seriously. Please don't change anything on your own. Just check with your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Atomoxetine page

“Atomoxetine (Strattera), the non-stimulant ADHD medicine, leaves the body mainly through one liver enzyme, CYP2D6, and that dependence is why this list deserves genuine care. Sixty of the 77 ingredients here, goldenseal and CBD among them, may slow that enzyme, letting atomoxetine build up along with side effects like a faster heartbea…”
