Study: Antidepressants May Be Linked to Antibiotic Resistance

The Facts
A new study from Australia's Queensland University has shown that the use of antidepressants may cause antibiotic resistance in the Escherichia coli (E. coli) bacteria. If accurate, the link would mirror the broader causal relationship between the resistance of disease-causing bacteria to antibiotics and the overprescription of those drugs.
The study compared one E. coli strain — MG1655 — to five antidepressants, including Prozac and Lexapro, and compared their strength against that of six types of antibiotics, such as beta [β] -lactams (penicillin derivatives) and macrolides (e.g. azithromycin, erythromycin).
The Spin
Narrative A
It is early days in studies concerning antidepressants and antibiotic resistance, and this evidence is not yet conclusive. However, we know for sure that the overuse of antibiotics itself causes problems for public health. Intensive farming methods mean most livestock and poultry are pumped with antibiotics which then enter humans through consumption. This, coupled with the contamination of our water supply, has left our species vulnerable to some of the world's most dangerous diseases.
Narrative B
The idea that antidepressants are linked to resistance to antibiotics has been known by the scientific community for years — this new research is only strengthening preexisting theories. As millions of people are set to die from this phenomenon in the coming decades, it's time to prioritize the issue, and look for ways to avoid what were once easily preventable deaths.
Narrative C
The drastic increase in antidepressant use over the last 30 years should, itself, be questioned. New research from University College London has shown that serotonin levels in those with depression are the same as those without, if not greater, suggesting that Big Pharma pushed the "chemical imbalance" theory of depression solely to make profits. If overuse of antidepressants could be contributing to antibiotic resistance, as well as causing unnecessary human suffering, the culture around their consumption may be in need of radical reform.
