Siberian Cocklebur and Gentamicin (IV)

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

Major

NEPHROTOXIC DRUGS

Why this applies to Gentamicin (IV)

Gentamicin (IV) falls under NEPHROTOXIC DRUGS — the group Siberian Cocklebur interacts with.

Siberian cocklebur can adversely affect the kidney. Theoretically, combining Siberian cocklebur with potentially nephrotoxic drugs might have additive harmful effects on kidney function.
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 Major Likelihood Likely Evidence B

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with this pairing. IV gentamicin is already one of the harder antibiotics on your kidneys. It's an aminoglycoside, and even on its own it can stress the kidneys, which is why doctors often check blood levels and kidney labs while you're on it. Siberian cocklebur contains naturally toxic compounds that can also harm the kidneys, so stacking the two could add up to more kidney damage than either alone.

This isn't about the herb changing how gentamicin is broken down. It's a double hit on the same organ. Watch for signs like making less urine, swelling, or feeling unusually tired. Please don't start or stop anything on your own. Loop in your doctor or pharmacist, since they're already monitoring your kidneys during treatment.

From our pharmacist’s overview on the Gentamicin (IV) page

“Kidney protection is the reason this list deserves real attention. Gentamicin (Garamycin) is an IV antibiotic that can stress the kidneys on its own, and both of the major-rated entries among the 35 supplements on file share that same weakness.”

About Siberian Cocklebur

What is Siberian Cocklebur?

  • Nasal congestion and sinus problems
  • Allergic rhinitis (hay fever)
  • Headache
  • Skin conditions and itching
  • Joint and muscle discomfort

Siberian cocklebur is a fruit used in traditional Chinese and other Asian herbal medicine, mainly for nasal congestion, sinus issues, and allergies. Human evidence is very limited, and the plant contains naturally toxic compounds that can cause serious poisoning, so it should only be used under expert guidance, if at all.

About Gentamicin Topical

What Is Gentamicin Topical Used For?

Brand name: Garamycin

Gentamicin sulfate topical is used to treat primary skin infections — infections that start directly in the skin — such as impetigo contagiosa, superficial folliculitis (infected hair follicles), furunculosis (boils), ecthyma, sycosis barbae, and pyoderma gangrenosum.

It also treats secondary skin infections, where bacteria have moved into already-irritated or damaged skin. This includes infected eczema, infected contact dermatitis (like poison ivy that gets infected), pustular acne, pustular psoriasis, infected seborrheic dermatitis, and bacterial infections on top of fungal or viral skin conditions. It has also been used successfully for infected stasis ulcers, infected superficial burns, infected insect bites and stings, infected lacerations and abrasions, paronychia (infected nail folds), and wounds from minor surgery.
