Whilst antibiotics can be a real lifesaver, they can also bring with them unwanted side effects. Antibiotics cannot distinguish between good and bad bacteria so indiscriminately wipe out both. Once both good and bad have been wiped out, harmful bacteria quickly proliferate and problems can soon start to arise.

Antibiotic use is the most common and significant cause of major decreases in healthy gut bacteria and the overgrowth of harmful bacteria. 

Antibiotics have also been associated with the development of unwanted gastrointestinal symptoms and even IBS. Antibiotic-associated diarrhoea is a common side effect of antibiotic use affecting up to 30% of adults and 40% of children and may occur between the initiation of therapy and up to 2 months after treatment stops.

Antibiotic-associated diarrhoea is thought to be the direct result of disturbance in the normal intestinal microflora, in particular infection with the harmful bacteria Clostridium difficile.

Saccharomyces Boulardii

If you need to take antibiotics and do experience unwanted side effects, supplementation with Saccharamoyces boulardii can be an effective way to relieve symptoms. Saccharomyces boulardii is a non-pathogenic yeast which has been shown to help support a healthy balance of flora. It is also resistant to antibiotics and can be recommended to patients whilst they are receiving antibiotics. Saccharomyces boulardii has been shown to be effective against harmful bacteria associated with antibiotic side effects such as Clostridium difficile. The effectiveness of Saccharomyces boulardii for the prevention of antibiotic side effects has been demonstrated in a number of clinical trials and meta-analyses1,2.

Probiotic Supplementation

Even if you don’t experience any obvious side effects during antibiotic therapy, it is still important to supplement with a high quality probiotic supplement once you have finished your course. This is to help replenish a healthy balance of microflora to reduce the risks of longer term effects. It is important at this stage to keep your diet as low in sugar as possible to avoid feeding the unwanted bacteria.   

✓ Choose Specific Probiotic Strains

Choose a probiotic supplement that contain a high level of specific strains that are comprehensively studied and have been shown to be effective. Some of the most comprehensively studied strains include Lactobacillus acidophilus NCFM®, Lactobacillus paracasei lpc-37, Bifidobacterium lactis Bi-07, Bifidobacterium lactis Bi-04 and Saccharomyces boulardii
