Probiotics: Preventing Complications of Antibiotic Use
Program Information
What are probiotics?

Probiotics are defined as “live microorganisms, which when consumed in adequate amounts, confer a health effect on the host”.1

The various probiotic formulations that are available are not equivalent to one another and differ on many important characteristics:

  • Composition
  • Strength of the formulation (measured in CFUs)
  • Manufacturing and production
  • Shelf-life of the probiotic
  • Ability to deliver bacteria to the gut (site of action)
  • Clinical evidence of efficacy
  • Health Canada approved indications (uses)

Some probiotics can prevent diarrhea which often occurs with antibiotic use (antibiotic-associated diarrhea or AAD) and can reduce the risk Clostridium difficile associated diarrhea (CDAD). Bio-K+, a proprietary formulation of L. acidophilus CL1285, L. casei LBC80R and L. rhamnosus CLR2 , is the only probiotic approved by Health Canada for the prevention of both AAD and CDAD.
