Limosilactobacillus Reuteri and Minocycline

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Minocycline

Minocycline falls under ANTIBIOTIC DRUGS — the group Limosilactobacillus Reuteri interacts with.

Theoretically, taking Limosilactobacillus reuteri with antibiotic drugs might decrease the effectiveness of L. reuteri.
L. reuteri 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. reuteri 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: minocycline is an antibiotic, and L. reuteri is a live probiotic. If you swallow them at the same time, the minocycline can kill off a good chunk of those helpful bacteria before they ever get to work. This doesn't make the minocycline weaker or more dangerous, and it won't change how it treats your infection or acne. The concern goes the other way around: you may simply waste the probiotic.

This is a theoretical, common-sense interaction rather than something proven in studies, so don't lose sleep over it. The easy fix is timing. Try to separate the two by at least two hours. If you have questions about spacing them out, your pharmacist can help you set up a simple schedule.

From our pharmacist’s overview on the Minocycline page

“This is one of the longer interaction lists I review, and with minocycline it earns real care rather than a shrug. Most entries pair this tetracycline antibiotic, taken for acne and other infections, with supplements that raise bleeding risk, and a second sizable group, beer and wine included, can add strain on the liver.”

About Limosilactobacillus Reuteri

What is Limosilactobacillus Reuteri?

  • Infant colic
  • Diarrhea (including antibiotic-associated)
  • Digestive health
  • Oral and gum health
  • Constipation
  • Immune support

Limosilactobacillus reuteri (formerly Lactobacillus reuteri) is a probiotic bacterium found in the human gut and certain fermented foods. It has the most supportive evidence for reducing crying in breastfed infants with colic and for some types of diarrhea, while many other uses remain unproven. It is generally well tolerated in healthy people, but people who are very ill or immunocompromised should talk to a doctor first.

About Minocycline

What Is Minocycline Used For?

Brand names: Vectrin, Dynacin, Minocin, Minocin IV, Solodyn, Acnamino MR, Minocin MR, Sebomin MR, Aknemin, Arestin Miscrosperes, Amzeeq, Zilxi

Minocycline is mainly used for infections caused by susceptible bacteria. Oral capsules and tablets, and Minocin intravenous (IV), are labeled for many infections. These include rickettsial infections such as Rocky Mountain spotted fever, Mycoplasma pneumoniae respiratory infections, chlamydia-related infections, plague, tularemia, cholera and brucellosis (with streptomycin). Some gram-negative bacterial infections are included when lab testing shows the bacteria respond.

Other minocycline products are not for infections at all. Extended-release tablets (including Minolira) treat inflammatory acne lesions in patients 12 and older. Amzeeq foam treats inflammatory acne in patients 9 and older. Zilxi foam and Emrosi capsules treat inflammatory rosacea lesions in adults. Arestin is placed in gum pockets by a dental professional for adult periodontitis.
