Aristolochia and Nusinersen Sodium

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

Moderate

NEPHROTOXIC DRUGS

Why this applies to Nusinersen Sodium

Nusinersen Sodium 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

Here's the simple version: Aristolochia is genuinely toxic to the kidneys. It contains aristolochic acid, which has caused real cases of kidney failure and is linked to cancer. Honestly, this is a supplement nobody should be taking at all, with or without other medicines.

With Spinraza (nusinersen), the worry on file is about adding two kidney stresses together. Spinraza can already affect the kidneys, and your care team usually checks your urine protein and kidney labs before doses. Stacking a known kidney toxin on top could theoretically make any kidney problems worse. This concern is based on how these substances behave, not on reported human cases. Spinraza is not a prodrug, so this isn't about changing how well it works. Please skip Aristolochia entirely and talk with your doctor or pharmacist.

From our pharmacist’s overview on the Nusinersen Sodium page

“Spinraza (nusinersen) is given by spinal injection to treat spinal muscular atrophy, and it carries its own warnings for low platelets and kidney stress, which makes the 208 supplements on this page worth real vigilance rather than a shrug. All but six of them, 202 ingredients, could raise bleeding risk by thinning the blood or dulling…”

About Aristolochia

What is Aristolochia?

Aristolochia
  • Promoting menstruation
  • Aphrodisiac
  • Immune stimulation
  • Snakebite remedies
  • Pain and inflammation

Aristolochia contains aristolochic acid, a potent toxin linked to severe kidney damage and cancer, and it is not safe to take. The FDA and other health authorities have warned against any product containing aristolochic acid. Despite its history in traditional medicine, no proven benefit outweighs these serious dangers.

About Nusinersen Injection

What Is Nusinersen Injection Used For?

Brand name: Spinraza

Spinraza (nusinersen) is used to treat spinal muscular atrophy (SMA) — a genetic disease that causes progressive muscle weakness by reducing the body's ability to make a protein called SMN (survival motor neuron). Spinraza is approved for pediatric and adult patients with SMA.

Spinraza is given by intrathecal injection — directly into the fluid surrounding the spinal cord — so the medicine can reach the central nervous system where it's needed most.
