Lactiplantibacillus Pentosus and Oritavancin Diphosphate

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Oritavancin Diphosphate

Oritavancin Diphosphate falls under ANTIBIOTIC DRUGS — the group Lactiplantibacillus Pentosus interacts with.

Theoretically, taking Lactiplantibacillus pentosus with antibiotic drugs might decrease the effectiveness of L. pentosus.
Lactiplantibacillus pentosus 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. pentosus 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: oritavancin (Orbactiv or Kimyrsa) is a powerful antibiotic given as an IV infusion, and its whole job is to kill bacteria. The catch is that probiotics like Lactiplantibacillus pentosus are themselves live, friendly bacteria. So the antibiotic can't really tell the difference and may wipe out a good chunk of the probiotic organisms you just took. That means it's the probiotic that loses its punch here, not the antibiotic. Your oritavancin will still work fine against your skin infection.

This concern is theoretical, based on how these products behave rather than hard studies. If you want the probiotic to survive, the usual tip is to space it at least two hours from antibiotic dosing. A quick word with your pharmacist can confirm timing for your situation.

From our pharmacist’s overview on the Oritavancin Diphosphate page

“Oritavancin (Orbactiv, Kimyrsa) is a long-acting antibiotic given as a single IV infusion for serious skin infections, and because one dose stays in the body for days, supplement timing matters more than usual. Even so, none of the 48 ingredients on file rise past moderate, so for most people this list is about knowing what to watch ra…”

About Oritavancin Injection

What Is Oritavancin Injection Used For?

Brand names: Orbactiv, Kimyrsa

Oritavancin injection — available as Orbactiv and Kimyrsa — is used to treat acute bacterial skin and skin structure infections (ABSSSI) in adults. These are serious skin infections caused by susceptible gram-positive bacteria, including Staphylococcus aureus (including MRSA), several Streptococcus species, and vancomycin-susceptible Enterococcus faecalis.

This antibiotic should only be used when a bacterial infection is confirmed or strongly suspected. Using it unnecessarily can contribute to antibiotic resistance.
