Lactobacillus Delbrueckii and Cefepime

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Cefepime

Cefepime falls under ANTIBIOTIC DRUGS — the group Lactobacillus Delbrueckii interacts with.

Theoretically, taking Lactobacillus delbrueckii with antibiotic drugs might decrease the effectiveness of L. delbrueckii.
Lactobacillus delbrueckii 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. delbrueckii 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: Cefepime is an antibiotic, and its whole job is to kill bacteria. The catch is that it can't tell the difference between the bacteria making you sick and the friendly Lactobacillus delbrueckii in your probiotic. So taking the two close together may wipe out a good chunk of those live probiotic organisms before they ever get to work.

To be clear, this goes one direction: cefepime can weaken the probiotic, not the other way around. Your antibiotic will still fight your infection just fine. This is a theoretical concern based on how antibiotics behave, so it's nothing to worry about, just space them out by at least two hours if you want the probiotic to have a fair shot. Your pharmacist can help you set up the timing.

From our pharmacist’s overview on the Cefepime page

“Cefepime (Maxipime) is a strong hospital antibiotic reserved for serious infections, and its interaction list warrants genuine caution, led by two major-rated herbs that can harm the kidneys: Siberian cocklebur and asarabacca, which is often contaminated with aristolochic acid, a kidney toxin the FDA considers unsafe. That matters more…”

About Cefepime Injection

What Is Cefepime Injection Used For?

Brand name: Maxipime

Cefepime injection is used to treat a range of serious bacterial infections in adults and children. These include moderate-to-severe pneumonia, uncomplicated and complicated urinary tract infections (including pyelonephritis, a kidney infection), uncomplicated skin and skin structure infections, and empiric therapy (treatment started before a specific germ is confirmed) for fever in patients with very low white blood cell counts (febrile neutropenia).

In adults, cefepime injection is also used to treat complicated intra-abdominal infections — but only when given together with another antibiotic called metronidazole. The intramuscular (IM) route is indicated only for mild-to-moderate uncomplicated or complicated urinary tract infections caused by E. coli.
