Asarabacca and Etodolac

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

Major

Nephrotoxic Drugs

Why this applies to Etodolac

Etodolac falls under Nephrotoxic Drugs — the group Asarabacca interacts with.

Asarabacca, a herbaceous plant, is often contaminated with aristolochic acid, a compound known for its nephrotoxic effects. Aristolochic acid can damage the kidneys and is deemed unsafe by the FDA, leading to the classification of products containing it as adulterated. When considering medications that may also pose a risk of kidney damage, caution is advised when combining them with asarabacca due to potential additive nephrotoxicity. It is advisable to consult healthcare professionals before using asarabacca alongside nephrotoxic drugs to minimize the risk of adverse effects on kidney function.
Severity Major Likelihood Possible Evidence C

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 concern with pairing these two. Etodolac is an NSAID, and like other drugs in that family it can put stress on your kidneys, especially with regular use, dehydration, or in older adults. Asarabacca is a plant that's often contaminated with aristolochic acid, which is known to seriously harm the kidneys. Stacking something hard on the kidneys with another kidney risk is the worry here. The effect could add up.

This isn't about etodolac being activated or blocked by the supplement. It's simply two kidney stressors together. Honestly, asarabacca isn't something I'd recommend at all because of that aristolochic acid risk. If you take etodolac, please skip the asarabacca and check with your pharmacist or doctor first.

From our pharmacist’s overview on the Etodolac page

“Etodolac (Lodine) is an NSAID for arthritis and other pain, and NSAIDs already stress the stomach lining and the kidneys, so the supplements on this page deserve more than a glance. Five of the 52 entries are rated major, and those five are where I would start reading.”

About Asarabacca

What is Asarabacca?

Asarabacca
  • Sinus and nasal congestion
  • Coughs and bronchial complaints
  • Inducing sweating
  • Inducing vomiting (emetic)
  • Digestive upset

Asarabacca is a European woodland plant traditionally used to clear the nose, cause sweating, or trigger vomiting, but it is rarely used today. It belongs to a plant family that often contains aristolochic acid, a substance the FDA considers unsafe because it can cause serious kidney damage and cancer, so we do not recommend using it.
