Study: Patients at greatest risk of self-harm right after starting antidepressants
Patients who take antidepressants are at highest risk of harming themselves in the weeks immediately after the drug is prescribed, according to a new analysis of more than 8.4 million electronic health records.
Why it matters: The Food and Drug Administration has warned since 2004 that antidepressants can increase suicidal behavior, but little is known about when the potential threat is greatest, researchers wrote.
- Antidepressants are also estimated to take up to eight weeks to begin working, with side effects common before mood lifts.
The details: The report from the research arm of electronic health records company Epic looked at data between 2017 and 2022 of patients with no history of self-harm or suicide attempts prior to being on antidepressants.
- The analysis doesn't breakdown types of self-harm, which can include but is not limited to attempted suicide.
- The 12-to-17 age group had the highest rate of self-harm at 0.39% and were nearly five times more likely to report a self-harm event in the first few months of being prescribed antidepressants compared to the general population.
- Teen girls, who the CDC in February found are experiencing record levels of sadness and violence, were especially at risk of self-harm.
- Men in the 18-to-24 age group, were slightly more likely to harm themselves than women the same age.
- Active antidepressant prescriptions also doubled between 2017 and 2022, signaling the increased use of depression treatment during the pandemic.
Worth noting: Although researchers did observe an increase in self-harm soon after patients started antidepressants, most first-time self-harm events occurred among patients (69%) who were not on antidepressant medication.
