Bifidobacterium Breve and Lincomycin HCl

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Lincomycin HCl

Lincomycin HCl falls under ANTIBIOTIC DRUGS — the group Bifidobacterium Breve interacts with.

Theoretically, taking Bifidobacterium breve with antibiotic drugs might decrease the effectiveness of B. breve.
Since B. breve preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. breve preparations by at least 2 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: lincomycin (Lincocin) is an antibiotic, and antibiotics don't tell the difference between unwanted bacteria and the friendly ones in your probiotic. Bifidobacterium breve is a live, active organism, so taking it at the same time as your lincomycin can kill off a good chunk of those helpful bacteria before they ever get to work. In other words, this isn't dangerous, it just makes your probiotic less effective.

The good news is this is easy to manage. Spacing the two apart by at least 2 hours usually gives the probiotic a better chance to survive. This advice is based on how these products work in theory rather than hard clinical proof, so it's a sensible precaution, not a cause for worry. Your pharmacist can help you set up a simple timing schedule.

From our pharmacist’s overview on the Lincomycin HCl page

“Lincomycin (Lincocin, Lincorex) is an antibiotic usually reserved for serious infections in people who cannot take penicillin, which is exactly why activated charcoal is the one entry here I take seriously. Charcoal binds drugs in the gut and can cut how much antibiotic your body actually receives, and with an infection bad enough to n…”

About Bifidobacterium Breve

What is Bifidobacterium Breve?

  • Digestive health and regularity

  • Diarrhea (including antibiotic-related)
  • Constipation
  • General immune and gut microbiome support

Bifidobacterium breve is a 'friendly' gut bacterium taken as a probiotic, most often to support digestion and balance the gut microbiome.

It is generally well tolerated in healthy people, but anyone with a weak immune system or serious illness should check with a doctor or pharmacist first.
