Siberian Cocklebur and Paracetamol

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Siberian Cocklebur interacts with whole categories of medication. Paracetamol falls into 2 of those categories, so it can interact with Siberian Cocklebur in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

Major

NEPHROTOXIC DRUGS

1 of 2

Why this applies to Paracetamol

Paracetamol 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 explains PharmD, Clinical Pharmacist

Here's the concern with pairing Siberian cocklebur and paracetamol (Panadol). Cocklebur fruit contains naturally toxic compounds that can stress the kidneys. Paracetamol, when taken at normal doses, is mostly easy on the kidneys, but in high doses or with long-term use it can add to that strain. Put the two together and the worry is an additive burden on your kidneys.

Keep in mind this is largely a theoretical concern based on cocklebur's known toxicity, not solid studies of this exact combo. Still, cocklebur itself can cause serious poisoning, so it's not something I'd recommend casually. Please check with your pharmacist or doctor before combining them, especially if you already have any kidney issues.

HEPATOTOXIC DRUGS

2 of 2

Paracetamol also falls under HEPATOTOXIC DRUGS.

Siberian cocklebur can adversely affect the liver. It has been linked to many cases of hepatotoxicity and some cases of liver failure. Theoretically, concomitant use with other potentially hepatotoxic drugs might increase the risk of developing liver damage. Some of these drugs include acarbose (Precose, Prandase), amiodarone (Cordarone), atorvastatin (Lipitor), azathioprine (Imuran), carbamazepine (Tegretol), cerivastatin (Baycol), diclofenac (Voltaren), felbamate (Felbatol), fenofibrate (TriCor), fluvastatin (Lescol), gemfibrozil (Lopid), isoniazid, itraconazole, (Sporanox), ketoconazole (Nizoral), leflunomide (Arava), lovastatin (Mevacor), methotrexate (Rheumatrex), nevirapine (Viramune), niacin, nitrofurantoin (Macrodantin), pioglitazone (Actos), pravastatin (Pravachol), pyrazinamide, rifampin (Rifadin), ritonavir (Norvir), rosiglitazone (Avandia), simvastatin (Zocor), tacrine (Cognex), tamoxifen, terbinafine (Lamisil), valproic acid, and zileuton (Zyflo).
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 pairing Siberian cocklebur and paracetamol (Panadol): both can be hard on your liver. Cocklebur naturally contains toxic compounds that have been tied to real cases of liver injury and even liver failure. Paracetamol is safe for most people at proper doses, but it's well known that too much, or combining it with other liver stressors, can damage the liver.

Stacking these two together may add up and raise your risk. Watch for warning signs like yellowing skin or eyes, dark urine, nausea, or pain in the upper right belly. Honestly, I'd steer clear of cocklebur given its toxicity, but please talk with your pharmacist or doctor before mixing it with paracetamol or changing anything.

See Every Supplement That Interacts With Paracetamol

This page covers Siberian Cocklebur only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Paracetamol page lists 155 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Wine (major) and Adrafinil (moderate).

By severity: 5 major · 114 moderate · 36 minor.

From our pharmacist’s overview on the Paracetamol page

“Nothing on this list concerns me more than alcohol for people who take paracetamol (Panadol) regularly. Beer and wine both carry major ratings because paracetamol is processed by the liver, and drinking on top of it raises the odds of genuine liver injury.”
