Lactobacillus Jensenii 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 Lactobacillus Jensenii interacts with.

Theoretically, taking Lactobacillus jensenii with antibiotic drugs might decrease the effectiveness of L. jensenii.
Lactobacillus jensenii 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. jensenii 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 an antibiotic, and antibiotics don't pick and choose. While oritavancin is busy fighting the bacteria causing your skin infection, it can also wipe out the friendly Lactobacillus jensenii organisms in a probiotic. So the worry runs the other way here. The probiotic isn't making your antibiotic dangerous; the antibiotic may just make your probiotic less useful by killing those live bacteria.

Good news: this concern is theoretical, and oritavancin is usually given as a single IV dose, so the overlap is brief. Your antibiotic will still treat your infection normally. If you want the probiotic to have a fair shot, take it well after your dose finishes. As always, check with your pharmacist or doctor before adding any supplement.

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 Lactobacillus Jensenii

What is Lactobacillus Jensenii?

  • Vaginal health
  • Maintaining healthy vaginal flora
  • Bacterial vaginosis support
  • Yeast infection support
  • General probiotic use

Lactobacillus jensenii is one of the natural 'good' bacteria found in a healthy vagina, and it is sometimes added to probiotic products marketed for vaginal health. While its role in the body is well recognized, there is only limited human research on taking it as a supplement, so the benefits are not proven. Talk with your pharmacist or doctor before using it, especially if you have a weakened immune system.

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.
