Probiotics 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 Probiotics interacts with.

Theoretically, taking antibiotic drugs with certain probiotics might decrease the effectiveness of probiotics.
Many probiotics are bacteria. Since these preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of sensitive organisms. Human research shows that taking probiotic concurrently with antibiotic treatment does not affect the diversity of the gut microbiome compared with antibiotic treatment in the absence of probiotics. Tell patients to separate administration of antibiotics and these 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: minocycline is an antibiotic, and probiotics are live bacteria. If you swallow them at the same time, the minocycline may kill off some of those friendly probiotic organisms before they can do their job. So this isn't about minocycline becoming stronger or weaker, your acne or infection treatment should work the same. It's the probiotic that may lose some punch.

The good news is this concern is mostly theoretical, and human studies haven't shown a big real-world problem. An easy fix is to space them out, taking your probiotic about two hours apart from your minocycline dose. If you're using a probiotic for a specific reason, check with your pharmacist on timing.

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 Probiotics

What is Probiotics?

  • Digestive health and regularity
  • Antibiotic-associated diarrhea
  • Irritable bowel syndrome (IBS)
  • Vaginal and urinary health
  • Immune support
  • General gut microbiome balance

Probiotics are live 'friendly' microbes that may help certain digestive conditions, such as antibiotic-associated diarrhea and some cases of IBS, though benefits depend heavily on the specific strain and dose. They are generally well tolerated for healthy people but should be used with caution by those with serious illness or weakened immune systems. Talk with your pharmacist or doctor to pick a product that matches your goal.

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.
