Gum Arabic and Cefixime

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

Moderate

ORAL DRUGS

Why this applies to Cefixime

Cefixime falls under ORAL DRUGS — the group Gum Arabic interacts with.

Theoretically, gum arabic can alter the absorption of oral drugs due to its fiber content.
Gum arabic has been used as a suspending osmotic agent in drug formulations. It might improve bioavailability of water-insoluble drugs like naproxen, but reduce absorption of polar drugs like amoxicillin. To avoid changes in absorption, take gum arabic 30-60 minutes after oral medications.
Severity Moderate Likelihood Possible Evidence B

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 cefixime (Suprax) and gum arabic. Gum arabic is a soluble fiber, and fibers like this can grab onto certain drugs in your gut and slow or lessen how much gets absorbed. Cefixime is a water-loving (polar) antibiotic, much like amoxicillin, so it's the kind of drug whose absorption could theoretically dip when taken right alongside a fiber supplement.

If less cefixime gets into your system, the worry isn't a side effect, it's that your infection may not get fully treated. To stay safe, the usual advice is to separate them: take your cefixime first, then wait about 30 to 60 minutes before the gum arabic. This concern is mostly theoretical, so don't stress, but do run your timing by your pharmacist or doctor.

See Every Supplement That Interacts With Cefixime

This page covers Gum Arabic 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 Gum Arabic

What is Gum Arabic?

Gum Arabic
  • Digestive and gut health
  • Source of soluble fiber
  • Constipation or bowel regularity
  • Prebiotic support
  • Cholesterol support
  • Blood sugar support

Gum arabic is a soluble dietary fiber from the acacia tree that is widely used as a safe food additive and is sometimes taken as a supplement for digestive health and as a prebiotic. Early studies suggest possible benefits for gut bacteria, cholesterol, and blood sugar, but the evidence is limited, and high doses can cause gas and bloating. Talk to your pharmacist or doctor before using it as a supplement.

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).
