Latilactobacillus Sakei and Cephradine

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Cephradine

Cephradine falls under ANTIBIOTIC DRUGS — the group Latilactobacillus Sakei interacts with.

Theoretically, taking Latilactobacillus sakei with antibiotic drugs might decrease the effectiveness of L. sakei.
Latilactobacillus sakei 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. sakei 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 simple version: Cephradine is an antibiotic, and like all antibiotics it doesn't know the difference between bad germs and the friendly bacteria in a probiotic like Latilactobacillus sakei. If you swallow them at the same time, the Cephradine can kill off a good chunk of those live probiotic organisms before they get a chance to do their job. So this isn't about Cephradine becoming dangerous or less effective at treating your infection. Your antibiotic still works fine. It's the probiotic that loses some of its punch.

An easy fix is to space them apart. Taking your L. sakei at least two hours away from your Cephradine dose helps more of it survive. This is based on how the two work together, not hard studies, so check with your pharmacist if you have questions.

From our pharmacist’s overview on the Cephradine page

“An antibiotic only works if it gets absorbed and your kidneys can handle it, and both of those are exactly what the riskiest supplements on this cephradine (Velosef) page threaten. Activated charcoal can grab cephradine in your gut and cut how much reaches your blood, while Siberian cocklebur and asarabacca can damage the kidneys that…”

About Latilactobacillus Sakei

  • Allergies
  • Gut and immune support
  • Skin health

Latilactobacillus sakei is a probiotic bacterium found in fermented foods like kimchi and certain meats, studied mostly for nasal sinus problems and eczema.
