Latilactobacillus Sakei and Erythromycin Stearate

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Erythromycin Stearate

Erythromycin Stearate 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: erythromycin is an antibiotic, and antibiotics don't know the difference between the bacteria making you sick and the friendly probiotic bacteria in a Latilactobacillus sakei supplement. If you swallow them at the same time, the erythromycin may kill off a good chunk of those live probiotic organisms before they can do anything. So this isn't about erythromycin becoming dangerous or less able to fight your infection. Your antibiotic should still work fine. The supplement is the one that loses out.

This is a theoretical concern based on how these products work, not hard proof. A common, easy fix is to space them apart by at least two hours. If you want, run your timing past your pharmacist or doctor.

From our pharmacist’s overview on the Erythromycin Stearate page

“Erythromycin stearate (Erythrocin, Ethril) is an antibiotic that asks for real vigilance around supplements. It blocks the body's main drug-clearing enzyme, so the largest share of this list is herbs whose blood levels can climb while you take it.”

About Latilactobacillus Sakei

What is Latilactobacillus Sakei?

  • Chronic rhinosinusitis and nasal congestion
  • Atopic dermatitis (eczema)
  • 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. Early research looks interesting, but evidence is still limited, so it should not replace proven treatments. Talk with a pharmacist or doctor before using it, especially if you have a weakened immune system.

About Erythromycin

What Is Erythromycin Used For?

Brand names: Erythro-S, Erythrocin, Ethril

Erythromycin treats bacterial infections caused by susceptible organisms. Oral and intravenous forms are used for upper and lower respiratory tract infections, skin and soft-tissue infections, pertussis (whooping cough), Legionnaires' disease, sexually transmitted infections (gonorrhea, syphilis, chlamydia), listeriosis, and other conditions. Erythrocin Lactobionate IV and erythromycin lactobionate injection are specifically for patients who cannot take oral medication or who need rapid, high blood levels due to severe infection — IV therapy should be switched to oral as soon as appropriate.

Erythromycin topical solution 2% and Ery 2% Pads (swabs) are indicated only for the topical treatment of acne vulgaris (acne) and are applied directly to the skin — they are not used for internal infections.
