Stinging Nettle and Benazepril, Hydrochlorothiazide

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

Moderate

DIURETIC DRUGS

Why this applies to Benazepril, Hydrochlorothiazide

Benazepril, Hydrochlorothiazide falls under DIURETIC DRUGS — the group Stinging Nettle interacts with.

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.
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 is the simple version. Your Lotensin HCT already pulls extra fluid out of your body, thanks to the hydrochlorothiazide (the water pill part) paired with benazepril, which relaxes your blood vessels. Stinging nettle has shown a mild water-pill-like effect too, but only in animal studies, not solid human research. So this is more of a theoretical heads-up than a proven problem.

If the effects did stack, you might notice more frequent urination, lightheadedness, or feeling drained or dizzy, especially when standing up. Food amounts of nettle are unlikely to matter much, but concentrated supplement doses are worth mentioning. Please check with your pharmacist or doctor before adding nettle, and don't change your blood pressure medicine on your own.

From our pharmacist’s overview on the Benazepril, Hydrochlorothiazide page

“Lotensin HCT (benazepril with hydrochlorothiazide) lowers blood pressure two ways at once, and that is exactly why this list deserves a careful read rather than a skim. Most of the interacting supplements either stack on that effect and drop pressure too far, or push against it and undo the control the drug provides.”

About Stinging Nettle

What is Stinging Nettle?

Stinging Nettle
  • Enlarged prostate (BPH) symptoms
  • Seasonal allergies
  • Joint pain and arthritis
  • Urinary symptoms / mild diuretic
  • Blood sugar support

Stinging nettle is a common plant used as food and in traditional medicine, most often for prostate symptoms, allergies, and joint pain. The evidence is mixed and mostly preliminary, so it is best thought of as a supportive option rather than a proven treatment. It is generally well tolerated, but pregnant and breastfeeding people should avoid it and everyone should check with a pharmacist or doctor first.
