Citalopram, dosage, side effects:
Citalopram is a selective serotonin reuptake inhibitor (SSRI) antidepressant used to treat depression, anxiety disorders, and other mood-related conditions. It works by increasing serotonin levels in the brain, which helps improve mood and reduce anxiety.

- Panic Disorder: Manages panic attacks.
- Off-Label Uses: Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), and social anxiety disorder.
2. Mechanism of Action
- SSRI: Inhibits serotonin reuptake, increasing serotonin availability in the brain.

5. Contraindications

- Medications: MAO inhibitors (risk of serotonin syndrome).
6. Precautions

7. Interactions
