Levilactobacillus Brevis and Tedizolid Phosphate

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Tedizolid Phosphate

Tedizolid Phosphate falls under ANTIBIOTIC DRUGS — the group Levilactobacillus Brevis interacts with.

Theoretically, taking Levilactobacillus brevis with antibiotic drugs might decrease the effectiveness of L. brevis.
Levilactobacillus brevis 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. brevis 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: Tedizolid (Sivextro) is an antibiotic, and antibiotics don't care whether bacteria are 'good' or 'bad.' So if you swallow your Levilactobacillus brevis probiotic at the same time as tedizolid, the medicine may kill off a chunk of those live, helpful bacteria before they ever get to work. The result isn't that your antibiotic becomes dangerous, it's just that your probiotic may not do much.

The good news is this is a theoretical concern based on how the two work, not a scary safety problem. Tedizolid keeps treating your skin infection just fine. If you want to keep taking the probiotic, a common tip is to space them at least two hours apart. Your pharmacist can help you fit the timing into your day.

About Levilactobacillus Brevis

What is Levilactobacillus Brevis?

  • Digestive health

  • Immune support
  • Oral and dental health
  • Vaginal health

Levilactobacillus brevis (formerly Lactobacillus brevis) is a lactic acid bacterium found in fermented foods like sauerkraut, pickles, and kimchi, and is used as a probiotic. Early research suggests possible benefits for gut and immune health, but strong human evidence is still limited. It is generally well tolerated in healthy people, but anyone with a weakened immune system or serious illness should talk to a doctor first.
