Ligilactobacillus Salivarius and Ozenoxacin

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Ozenoxacin

Ozenoxacin falls under ANTIBIOTIC DRUGS — the group Ligilactobacillus Salivarius interacts with.

Theoretically, taking Ligilactobacillus salivarius with antibiotic drugs might decrease the effectiveness of L. salivarius.
Ligilactobacillus salivarius 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. salivarius 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: this interaction runs the other way from what people usually worry about. The probiotic doesn't weaken your antibiotic. Instead, the antibiotic can weaken the probiotic. Ligilactobacillus salivarius is a live bacterium, and antibacterial drugs are designed to kill bacteria, so taking them too close together may wipe out some of those helpful organisms before they get to do their job.

The good news with ozenoxacin (Xepi) is that it's a cream you rub on your skin to treat impetigo, so very little gets into the rest of your body. The two are unlikely to bump into each other much. This concern is theoretical and based on how antibiotics behave, not on real cases. If you ever take an oral antibiotic alongside this probiotic, spacing them about two hours apart is a smart, simple move. Check with your pharmacist if you're unsure.
