GoKawiilScientists still can't fully explain how SSRIs work despite decades of use
Researchers acknowledge that although SSRIs remain among the world's most widely prescribed medications, the precise biological mechanism by which they relieve depression is still not understood. The debate intensified after US Health Secretary Robert F. Kennedy Jr. claimed the drugs are overprescribed and carry withdrawal risks comparable to heroin, sparking pushback from some clinicians while others said he raised a legitimate concern.
GoKawiil's interpretation of the reporting above, not reported fact.
Millions of patients are prescribed a treatment whose therapeutic pathway is still contested among experts, which complicates public trust and policy decisions around mental health care. Political statements about drug safety, even if imprecise, can shape prescribing behavior and patient fears, making accurate scientific communication especially consequential.
- SSRIs remain among the most prescribed drugs despite an incomplete scientific understanding of their mechanism.
- RFK Jr.'s claims about overuse and withdrawal risks sparked disagreement among scientists over whether he overstated or rightly flagged a real issue.
- Researchers say depression likely has multiple biological pathways, meaning no single explanation fits all patients.
