Carob and Cefixime

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

Minor

ORAL DRUGS

Why this applies to Cefixime

Cefixime falls under ORAL DRUGS — the group Carob interacts with.

Theoretically, carob might also impair the absorption of oral drugs.
Laboratory research shows that carob, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Take carob 30-60 minutes after oral medications.
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 carob and your Cefixime (Suprax). Carob is fiber-rich and full of tannins, compounds that can grab onto things in your gut. The concern, and it's a theoretical one based only on lab work, is that carob may bind up an antibiotic like cefixime and keep some of it from being absorbed. If less gets into your bloodstream, the medicine may not fight your infection as well, which is the last thing you want when you're trying to clear something up.

Cefixime is not a prodrug, so this is simply about absorption, not how your body activates it. An easy fix: take your cefixime first, then wait about 30 to 60 minutes before having carob. A sprinkle of carob in food likely matters far less than concentrated carob supplements. Check with your pharmacist if you're unsure.

See Every Supplement That Interacts With Cefixime

This page covers Carob only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefixime page lists 60 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefixime page

“Cefixime (Suprax) is an oral antibiotic for bacterial infections, and this list of 60 supplements and herbs deserves a careful read, because three entries are rated major. Siberian cocklebur and asarabacca can both damage the kidneys, and activated charcoal can soak up the antibiotic in your gut so less of it reaches your blood.”

About Carob

What is Carob?

Carob
  • Diarrhea (especially in children)
  • Cocoa/chocolate substitute
  • Digestive upset
  • Acid reflux/heartburn
  • Source of dietary fiber

Carob is a Mediterranean tree whose pods are widely used as a caffeine-free, naturally sweet cocoa alternative and as a thickener (carob gum). It is mostly eaten as a food and is generally well tolerated, and carob pod preparations have some traditional and limited research use for diarrhea, but evidence for most medicinal claims is limited. Check with your pharmacist or doctor before using it as a treatment, especially for infants or children.

About Cefixime

What Is Cefixime Used For?

Brand name: Suprax

Cefixime treats several bacterial infections in adults and children six months and older. These include uncomplicated urinary tract infections (UTIs), otitis media (ear infections), pharyngitis and tonsillitis (strep throat and tonsil infections), acute exacerbations of chronic bronchitis (sudden worsening of ongoing bronchitis), and uncomplicated gonorrhea (cervical or urethral).

Cefixime tablets are indicated only for adults and children weighing more than 45 kg or older than 12 years, and tablets are not approved for otitis media — ear infections must be treated with the oral suspension or, where available, chewable tablets. Cefixime oral suspension and capsules are approved for the same infections across the full pediatric age range (six months and older).
