Lactiplantibacillus Pentosus and Amikacin

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Amikacin

Amikacin 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: amikacin is a strong antibiotic, and its whole job is to kill bacteria. The catch is that Lactiplantibacillus pentosus is itself a live, friendly bacterium. So if you take them at the same time, the amikacin may wipe out a good chunk of those probiotic organisms before they can do anything useful. This doesn't hurt you, and it doesn't change how well your amikacin fights your infection. It just makes the probiotic less likely to work.

This concern is based on how these products behave in theory, not on hard studies. A practical fix is to space them out, taking the probiotic a couple of hours apart from your antibiotic. Since amikacin is usually given as an injection in a medical setting, check with your pharmacist or doctor about the best timing for you.

From our pharmacist’s overview on the Amikacin page

“The supplements that deserve genuine wariness with amikacin (Amikin, Arikayce) are the ones that touch the kidneys. Amikacin is a potent antibiotic that can strain kidney function on its own, so herbs like Siberian cocklebur and asarabacca (often contaminated with aristolochic acid, a known kidney toxin) should stay off the table durin…”

About Amikacin Oral Inhalation

What Is Amikacin Oral Inhalation Used For?

Arikayce is approved for adults with refractory Mycobacterium avium complex (MAC) lung disease — a serious bacterial lung infection that has not responded to at least 6 consecutive months of a standard multidrug antibiotic regimen. It is used as part of a combination treatment plan, not on its own.

This approval is limited: Arikayce is intended only for adults who have few or no other treatment options. It is not recommended for patients whose MAC lung disease has not yet failed standard therapy.
