Guarumo 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 Guarumo interacts with.

In an animal study, an aqueous extract of guarumo depressed the central nervous system, inducing significant motor incoordination and muscle relaxant activity. Theoretically, guarumo might potentiate the sedative effects of drugs.
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 with Lorazepam (Ativan) and guarumo. Lorazepam already calms brain activity to ease anxiety and help with sleep. In one animal study, a water extract of guarumo also had a calming, muscle-relaxing effect on the nervous system. So the worry is simple: stacking the two could add up, leaving you more drowsy, foggy, dizzy, or unsteady on your feet than you'd expect from your Lorazepam alone.

I want to be honest about the strength here. This is based on a single animal study, not human evidence, so it's more theoretical than proven. Still, since both can dampen the nervous system, I wouldn't combine them on your own. Please run it by your pharmacist or doctor first, and never adjust your Lorazepam without their okay.

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 Guarumo

What is Guarumo?

Guarumo
  • Type 2 diabetes / blood sugar support
  • High blood pressure
  • Cough, asthma, and bronchitis
  • Heart failure symptoms
  • Liver and rheumatic complaints

Guarumo (Cecropia obtusifolia) is a tropical tree used in Latin American traditional medicine, most often as a leaf tea for diabetes and high blood pressure. Some early laboratory and small human studies suggest it may modestly affect blood sugar, but the evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using it, especially if you have a chronic condition or take medication.

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.
