Asian Water Plantain and Cefoxitin

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

Minor

Nephrotoxic Drugs

Why this applies to Cefoxitin

Cefoxitin falls under Nephrotoxic Drugs — the group Asian Water Plantain interacts with.

Studies on animals have shown that Asian water plantain extract, which contains triterpenoids, is generally safe at doses up to 1440 mg/kg orally daily and does not cause harm to the body. However, using a higher dose of the extract, at 33.3 grams/kg orally for 60 days, has been linked to kidney issues, as indicated by increased blood urea nitrogen levels, and enlargement of the liver and kidneys. Additionally, two components of Asian water plantain, alisol A and alisol B, when given in doses of 400 mg/kg daily and 500 mg/kg daily respectively for 6 months, have been found to increase the production of markers that suggest potential kidney damage from certain medications. While these findings suggest there is very little risk that Asian water plantain may interact with drugs that are harmful to the kidneys, caution is still advised if combined with known nephrotoxic drugs (source: pubmed.ncbi.nlm.nih.gov/28408883/)
Severity Minor Likelihood Unlikely Evidence A

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the gist for cefoxitin (Mefoxin). This antibiotic is given by injection and, like many cephalosporins, your kidneys do the work of clearing it out. The concern with Asian water plantain is that, at very high doses in animal studies, some of its triterpenoid compounds (alisol A and B) nudged up markers that hint at kidney stress. So the worry is simply two things that lean on the kidneys being used together.

The good news: this is rated minor and unlikely. The kidney signals only showed up at huge doses in animals, not in people taking normal amounts. Cefoxitin isn't a prodrug, so the supplement wouldn't make it stronger or weaker, the real issue is added kidney burden. Since cefoxitin is usually a short hospital course, mention any supplements to your pharmacist or doctor first.

“Cefoxitin (Mefoxin) is an injectable antibiotic, usually given in a hospital or clinic for serious infections, and its supplement list deserves genuine care rather than a quick skim.

About Asian Water Plantain

What is Asian Water Plantain?

Asian Water Plantain
  • Promoting urination (diuretic)
  • Fluid retention and swelling
  • Urinary discomfort
  • Cholesterol and heart health support
  • Kidney and bladder support

Asian water plantain (Ze Xie) is a rhizome long used in traditional Chinese medicine, mainly as a diuretic and for fluid retention. Modern evidence is mostly limited to laboratory and animal studies, so its benefits in people are not well proven, and quality human safety data are lacking. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

About Cefoxitin Injection

What Is Cefoxitin Injection Used For?

Brand name: Mefoxin

Cefoxitin for Injection and Dextrose Injection is used to treat bacterial infections in many parts of the body, including the lungs (pneumonia), urinary tract, abdomen, female reproductive system, bloodstream (septicemia), bones and joints, and skin. It works only against bacteria — not viruses.

Cefoxitin for Injection and Dextrose Injection is also used to prevent infection in people having certain surgeries, including gastrointestinal surgery, vaginal hysterectomy, abdominal hysterectomy, or cesarean section. It does not have activity against Chlamydia trachomatis, so additional medication may be needed when that germ is suspected.
