Probiotics and Tedizolid Phosphate

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

Moderate

ANTIBIOTIC DRUGS

Why this applies to Tedizolid Phosphate

Tedizolid Phosphate 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: probiotics are live, friendly bacteria, and Sivextro (tedizolid) is an antibiotic that kills bacteria. So if you take them at the same moment, the antibiotic may wipe out some of those good bugs before they get a chance to settle in your gut. The concern runs one direction here: it's the probiotic that may lose some punch, not your antibiotic. Tedizolid still treats your skin infection just fine.

This is a theoretical, lower-level concern, and some human studies suggest the overall effect on the gut is small. A practical tip is to space them out, taking your probiotic about two hours apart from your tedizolid dose. If you want help timing it, just ask your pharmacist or doctor.

“Nearly every supplement interaction on file for tedizolid phosphate (Sivextro), an antibiotic used for serious skin infections, points the same way. The antibiotic can kill the live organisms in probiotic products, which weakens the probiotic, not the drug.”

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.
