Depression from Opioids: Causes, Risks, and What to Do

When people take opioids for pain, they often expect relief—not a worsening mood. But depression from opioids, a well-documented side effect tied to brain chemistry changes from long-term opioid use. Also known as opioid-induced depressive disorder, it’s not just feeling sad—it’s a real, measurable drop in motivation, energy, and joy that sticks around even after the pain fades. This isn’t rare. Studies show up to half of long-term opioid users develop symptoms that meet clinical criteria for depression. And it’s not always clear if the pain caused the low mood, or if the drugs did.
