The Claim
Fluoxetine modestly increases anxiety levels, as measured by the Beck Anxiety Inventory (BAI), in adults with chronic tinnitus, while simultaneously reducing depressive symptoms, as measured by the Beck Depression Inventory (BDI), indicating a dissociation between its effects on anxiety and depression in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with chronic tinnitus, fluoxetine increases anxiety levels while decreasing depressive symptoms, showing that its effects on anxiety and depression are not the same.
See the scientific wording
Fluoxetine modestly increases anxiety levels (BAI) in adults with chronic tinnitus, despite reducing depressive symptoms (BDI), suggesting a dissociation between its effects on mood and anxiety in this population.
Fluoxetine increases serotonin in the brain, which calms sadness circuits but overstimulates fear circuits, making anxiety worse even as mood improves.
What the research says
1 studyIn people with long-term ringing in the ears, fluoxetine made them feel less sad but more anxious — which is surprising because we usually expect the same drug to help both. This suggests it affects mood and anxiety differently in this group.
