The Risks of Oral Antibiotics


According to the Journal of American Society of Nephrology (JASN), research published in 2018 revealed that oral antibiotics are a risk factor for kidney stones. Health records for 13 million children and adults in the U.K. were reviewed, showing that exposure to five classes of oral antibiotics were associated with kidney stones within three to 12 months post-use. According to, five classes of oral antibiotics have been identified as risk factors for kidney stones: broad-spectrum penicillin, fluoroquinolones, nitrofurantoin, cephalosporins and sulfas.  The association is most pronounced among younger children, and remains statistically significant for up to five years after exposure, except for broad-spectrum penicillin.

Between 1997 and 2012, the annual incidence of kidney stone disease rose by 16%. The highest increase was seen in 15- to 19-year-olds, among whom the incidence rate increased 26% per 5 years.  As reported by NBC News, July 8, 2023, data show kidney stones are now occurring in younger people, particularly among teenage girls, and diets high in ultra processed foods and increased use of antibiotics early in life are thought to be among the key contributors to this trend.

Previous studies have found an association between oral antibiotics and inflammatory bowel disease (IBD) and colorectal cancer, likely due to disruption of gut microbiome.  Fluoroquinolones, which are frequently prescribed for upper respiratory infections and urinary tract infections (UTIs) have been linked to an increased risk for aortic dissection (tears in the aorta), which can be fatal.

There are times when antibiotics can save lives, but it is best not to rely on the common use of
antibiotics, especially the 5 classes listed above, particularly in our youth.  The purpose of antibiotics is to kill bad bacteria, but they also kill good bacteria.  Eating fermented foods or taking quality probiotics can safely replenish the good bacteria in the gut.  Please speak with one of our Natural Living associates to determine which probiotic may be best for you.
