Compare Xanax vs. Prozac

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Alprazolam (Xanax) and fluoxetine (Prozac) are both used to treat mental health conditions, but they work differently and are used for different purposes. Alprazolam is a benzodiazepine that treats generalized anxiety disorder (GAD) and panic attacks. It works quickly, often within 30 minutes, but it can be habit-forming and is meant for short-term use. Common side effects include drowsiness and memory problems. On the other hand, fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used to treat depression, obsessive-compulsive disorder (OCD), bulimia, and panic disorder. It takes longer to feel the full effects, usually 1-2 months, and can cause side effects like headaches and difficulty sleeping. Unlike alprazolam, fluoxetine is not habit-forming and is not a controlled substance.

    Alprazolam (Xanax) is a benzodiazepine. It's approved to treat generalized anxiety disorder (GAD) and panic attacks in adults.

    Fluoxetine (Prozac) is a selective serotonin reuptake inhibitor (SSRI). It's used to treat several mental health conditions, including depression and panic disorder. The immediate-release pill and liquid are taken by mouth, typically once or twice daily. The delayed-release capsule is taken weekly, but it's approved only for depression. Some common side effects of fluoxetine (Prozac) include headaches, difficulty sleeping, and tiredness. Don't suddenly stop this medication if you've been taking it for a while; doing so can lead to symptoms of withdrawal.
