Aristolochia and Hydrochlorothiazide, Propranolol

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

Moderate

NEPHROTOXIC DRUGS

Why this applies to Hydrochlorothiazide, Propranolol

Hydrochlorothiazide, Propranolol falls under NEPHROTOXIC DRUGS — the group Aristolochia interacts with.

Aristolochia is nephrotoxic. There are numerous cases of nephropathy and renal failure associated with aristolochia use. Theoretically, combining aristolochia with potentially nephrotoxic drugs might have additive adverse effects on kidney function. However, this interaction has not yet been reported in humans. Close monitoring of renal function in patients taking aristolochia with nephrotoxic drugs may be warranted.
Some potentially nephrotoxic drugs include cyclosporine (Neoral, Sandimmune); aminoglycosides including amikacin (Amikin), gentamicin (Garamycin, Gentak, others), and tobramycin (Nebcin, others); nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen (Advil, Motrin, Nuprin, others), indomethacin (Indocin), naproxen (Aleve, Anaprox, Naprelan, Naprosyn), piroxicam (Feldene); and numerous others.
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

Let me start with the big picture: Aristolochia is a supplement you really should not be taking at all. It contains aristolochic acid, which is directly toxic to the kidneys and has been tied to kidney failure and cancer. That concern stands on its own, no matter what medicine you pair it with.

Your combo pill, Inderide, holds hydrochlorothiazide (a water pill) and propranolol (a beta blocker). The worry here is mostly with the hydrochlorothiazide side, since water pills lean on your kidneys and can shift your fluid balance. Stacking a kidney-damaging herb on top could, in theory, add extra strain and may show up as dizziness, weakness, or changes in urination. To be fair, this particular pairing is theoretical and has not been reported in people. Even so, please skip the Aristolochia and check with your pharmacist or doctor.

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

“Inderide combines hydrochlorothiazide, a water pill, with propranolol, a beta blocker, so a supplement that also lowers blood pressure or pulls potassium out of the body hits the drug on its own turf. That describes most of this list, and I'd approach it with genuine care.”
