Aristolochia and Salsalate

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

Moderate

NEPHROTOXIC DRUGS

Why this applies to Salsalate

Salsalate 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 explains PharmD, Clinical Pharmacist

Let me be straight with you about Aristolochia first: this is one supplement I would steer clear of entirely. It contains aristolochic acid, which is well documented to cause serious kidney damage and is even linked to cancer. The FDA has warned against any product containing it, so this isn't a close call.

Now add Salsalate, an NSAID-type pain reliever. Salsalate can already reduce blood flow to the kidneys and stress them, especially with long-term use or in people who are dehydrated. Pairing it with something already toxic to the kidneys could, in theory, add up to greater harm. This particular combo hasn't been reported in people yet, so the concern is based on how each works rather than real cases. Still, the safest move is to avoid Aristolochia and check in with your pharmacist or doctor.

From our pharmacist’s overview on the Salsalate page

“Beer and wine top my worry list for anyone taking salsalate (Disalcid), an aspirin-like salicylate used for arthritis pain, since alcohol alongside it raises the risk of stomach and intestinal bleeding. Those drinks account for two of the five major-rated interactions among the 37 ingredients on file, and this list deserves real caution.”
