Rhodiola and Benazepril

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Benazepril

Benazepril falls under ANTIHYPERTENSIVE DRUGS — the group Rhodiola interacts with.

Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
In vitro and animal research shows that rhodiola extract inhibits angiotensin-converting enzyme (ACE) and might lower blood pressure.
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 Benazepril (Lotensin) and Rhodiola. Benazepril is an ACE inhibitor, meaning it lowers your blood pressure by blocking the ACE enzyme. Interestingly, lab and animal studies hint that Rhodiola may block that same enzyme a little, plus relax blood vessels. So in theory, pairing the two could nudge your blood pressure lower than expected.

If that happened, you might feel dizzy, lightheaded, tired, or shaky, especially when standing up quickly. I want to be honest though: this is theoretical, drawn only from test-tube and animal research, so it's far from certain in real people. If you take Benazepril and want to try Rhodiola, check with your pharmacist or doctor first, and keep an eye on how you feel.

About Rhodiola

What is Rhodiola?

Rhodiola
  • Fatigue and low energy
  • Stress and coping (adaptogen)
  • Mental performance and focus
  • Mild depression
  • Physical and exercise performance

Rhodiola is an herb traditionally used to fight fatigue and help the body cope with stress. Some small studies suggest it may modestly reduce fatigue and improve mood, but the evidence is limited and not strong. It is generally well tolerated for short-term use, but talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

About Benazepril

What Is Benazepril Used For?

Brand name: Lotensin

Benazepril — sold as Lotensin and under the generic names Benazepril and Benazepril Hydrochloride — is approved to treat high blood pressure (hypertension). Lowering blood pressure reduces the risk of serious cardiovascular events, including strokes and heart attacks.

It can be used on its own or combined with a thiazide diuretic (water pill) when blood pressure needs extra control. Lotensin is specifically indicated for the treatment of hypertension to lower blood pressure.
