Latilactobacillus Sakei and Erythromycin

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Erythromycin

Erythromycin 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: Latilactobacillus sakei is a live probiotic, and erythromycin is an antibiotic whose whole job is to stop bacteria from growing. If you swallow them at the same time, the erythromycin can kill off a good chunk of those probiotic bugs before they ever get a chance to help you. So this isn't about erythromycin becoming dangerous or weaker. Instead, the probiotic is the one that loses out.

The good news is this is easy to manage. Most experts suggest spacing them apart by at least two hours so the antibiotic isn't sitting right next to the live cultures. Keep in mind this is based on how these products work in theory, not strong human studies. If you take both regularly, just run your timing past your pharmacist or doctor.

From our pharmacist’s overview on the Erythromycin page

“Erythromycin calls for more supplement caution than most antibiotics, and the reason is one liver enzyme, CYP3A4. Erythromycin both blocks that enzyme and is broken down by it, so grapefruit can push erythromycin levels up while St.”

About Latilactobacillus Sakei

What is Latilactobacillus Sakei?

  • Chronic rhinosinusitis and nasal congestion

  • 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.
