White Pepper and Cefotaxime

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

Minor

CEFOTAXIME (Claforan)

Evidence from animal research shows that piperine, a constituent of white pepper, increases the plasma levels of cefotaxime when taken concomitantly. Theoretically, piperine from white pepper might increase the effects and side effects of cefotaxime in humans. Be watchful with this combination.
Severity Minor 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 gist with white pepper and cefotaxime, the injectable antibiotic. The active compound in pepper, piperine, may make your body hold onto a bit more cefotaxime, so levels in the blood could run slightly higher. In theory that means a touch more antibiotic effect, but also a slightly higher chance of its usual side effects, like loose stools or stomach upset, mild rash, or irritation at the injection site.

Now, the honest part: this comes from animal research only, and it's rated a minor interaction. Normal seasoning amounts of white pepper on your food are very unlikely to cause any real trouble. Concentrated piperine supplements are the bigger question mark. Since cefotaxime is given in a hospital or clinic, just mention any supplements you take to your pharmacist or doctor.

See Every Supplement That Interacts With Cefotaxime

This page covers White Pepper only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefotaxime page lists 45 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate), Aristolochia (moderate) and Bacillus Coagulans (moderate).

By severity: 2 major · 39 moderate · 4 minor.

From our pharmacist’s overview on the Cefotaxime page

“The two entries worth understanding first on this cefotaxime (Claforan) list are Siberian cocklebur and asarabacca. Both can damage the kidneys on their own, and stacking that on an injectable antibiotic often given to people who are already quite sick is a risk I would not take lightly.”

About White Pepper

What is White Pepper?

  • Digestive upset
  • Seasoning and appetite support
  • Cough and cold remedies (traditional)
  • Minor aches and pains (traditional)
  • Antimicrobial (traditional)

White pepper comes from the same plant as black pepper and is mostly used as a kitchen spice. In normal food amounts it is generally safe for most people, but there is little solid human research supporting its use as a medicine. Talk with your pharmacist or doctor before using concentrated supplements, especially if you are pregnant, breastfeeding, or have a health condition.

About Cefotaxime Injection

What Is Cefotaxime Injection Used For?

Brand name: Claforan

Cefotaxime Injection is used to treat serious bacterial infections in many parts of the body — including the lungs, urinary tract, skin, bones and joints, abdomen, reproductive organs, and central nervous system (such as meningitis). It also treats bloodstream infections (septicemia) and certain sexually transmitted infections, including gonorrhea.

It is also given before certain surgeries — such as abdominal or vaginal hysterectomy, gastrointestinal surgery, and cesarean section — to reduce the risk of postoperative infection. Because cefotaxime has no activity against Chlamydia trachomatis, an additional antibiotic must be added when that organism is a suspected cause of pelvic inflammatory disease.
