Can Prozac cause anxiety? I know some selective serotonin inhibitors, such as Prozac, are prescribed for anxiety, but can they also cause anxiety?
Prozac (the generic drug fluoxetine) is a selective serotonin reuptake inhibitor (SSRI) and is primarily prescribed as an antidepressant, but also as an anxiolytic.

The side effects of fluoxetine indeed include anxiety, but this is a rare phenomenon (source: Drugs.com). The more common complaints are restlessness and skin rash. In fact, Mayo Clinic doesn't even list anxiety as a general side effect of SSRIs.
