Citalopram (Celexa) for Anxiety and Depression
Understanding this effective SSRI for mood and anxiety disorders
What is Citalopram?
Citalopram (brand name Celexa) is a selective serotonin reuptake inhibitor (SSRI) antidepressant. While primarily FDA-approved for major depressive disorder, it's widely used off-label for various anxiety disorders due to its effectiveness and tolerability.
Citalopram is often chosen as a first-line treatment because it has fewer drug interactions than many other SSRIs and is generally well-tolerated by most patients.

How Citalopram Works
Citalopram increases serotonin levels in the brain by blocking its reuptake. Serotonin is a neurotransmitter that plays a key role in regulating mood, anxiety, and emotional well-being.
Key Benefits:
- • Selective action (fewer side effects than older antidepressants)
- • Once-daily dosing for convenience
- • Minimal drug interactions
- • Well-established safety profile
