Lacticaseibacillus Rhamnosus and Capreomycin

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Capreomycin

Capreomycin falls under ANTIBIOTIC DRUGS — the group Lacticaseibacillus Rhamnosus interacts with.

Theoretically, taking Lacticaseibacillus rhamnosus with antibiotic drugs might decrease the effectiveness of L. rhamnosus.
L. rhamnosus 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. rhamnosus 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 goes one way, and it's about the probiotic, not the medicine. Capreomycin is an injected antibiotic used mainly to treat tuberculosis, and like other antibiotics it doesn't tell the difference between harmful bacteria and the friendly bacteria in a probiotic. So if the two overlap closely in time, the antibiotic may kill off a good chunk of the live L. rhamnosus organisms before they can do their job.

The good news is your capreomycin treatment itself isn't weakened, and this is a theoretical concern based on how the two work, not strong proof. To get more out of the probiotic, just space them out, and check with your pharmacist or doctor about the best timing for you.
