Goldenseal and Lorazepam

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

Moderate

CNS DEPRESSANTS

Why this applies to Lorazepam

Lorazepam falls under CNS DEPRESSANTS — the group Goldenseal interacts with.

Theoretically, goldenseal might increase the sedative effects of CNS depressants.
Goldenseal contains berberine. Animal research shows that berberine can have sedative effects. However, this effect has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the gist for lorazepam (Ativan): this is a calming benzodiazepine that already slows down activity in your brain to ease anxiety. Goldenseal contains a compound called berberine, and in animal studies berberine showed some sedating effects of its own. The concern is simply that two calming things stacked together could add up, leaving you more drowsy, foggy, or unsteady than you'd expect from your usual lorazepam dose.

I want to be honest about the strength of this one: it's theoretical. The sedation has not actually been reported in people, only suggested by lab and animal work. So I wouldn't panic. Still, if you notice extra grogginess or dizziness, mention it to your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Lorazepam page

“Lorazepam (Ativan) works by slowing brain activity, and that is exactly why this list deserves real caution. Of the 119 supplement and herbal ingredients on file, 78 are themselves nervous-system depressants, so adding them can deepen drowsiness or, at the extreme, slow breathing.”

About Lorazepam

What Is Lorazepam Used For?

Brand name: Ativan

Lorazepam tablets (Ativan and generic) and the oral solution are used to manage anxiety disorders or for short-term relief of anxiety symptoms, including anxiety that comes with depressive symptoms. Loreev XR, an extended-release capsule, is specifically indicated for adults with anxiety disorders who are already stable on lorazepam tablets taken three times daily.

Ativan and generic lorazepam injections are used in two additional situations: treating status epilepticus (a medical emergency involving prolonged or repeated seizures) and as a pre-surgery medication in adults to produce sedation, ease anxiety, and reduce memory of events on the day of surgery.
