Lacticaseibacillus Paracasei and Ceftibuten

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Ceftibuten

Ceftibuten falls under ANTIBIOTIC DRUGS — the group Lacticaseibacillus Paracasei interacts with.

Theoretically, taking Lacticaseibacillus paracasei with antibiotic drugs might decrease the effectiveness of L. paracasei.
L. paracasei preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. paracasei preparations by at least two hours.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the thing to keep in mind: ceftibuten (Cedax) is an antibiotic, and its whole job is to kill bacteria. Your probiotic, Lacticaseibacillus paracasei, is made of live, helpful bacteria. So when you take them at the same time, the antibiotic can wipe out a good chunk of those probiotic organisms before they ever get to work. This doesn't make the ceftibuten less effective or more dangerous, it just shortchanges the probiotic.

The good news is this is easy to manage. A simple fix is to space them out, taking your probiotic at least two hours apart from your ceftibuten dose. This is based on how these products work rather than hard clinical studies, so it's more of a common-sense step than a serious warning. If you're unsure about timing, your pharmacist can help you map it out.

From our pharmacist’s overview on the Ceftibuten page

“What worries me most with ceftibuten, an oral cephalosporin antibiotic used for bronchitis and ear, throat, and urinary infections, are the supplements that can stress the kidneys. Siberian cocklebur and asarabacca, the latter often tainted with kidney-damaging aristolochic acid, may add to that injury, and activated charcoal can soak…”
