Escitalopram vs. Citalopram: A Comparison for Depression and Anxiety
Escitalopram and citalopram are both antidepressant medications known as SSRIs, commonly prescribed for mood disorders. Patients often compare them because escitalopram is a purified version of citalopram, leading to similar effects but with some key differences in indications and dosing.

|---|---|---|
| Drug Class | Selective Serotonin Reuptake Inhibitor (SSRI) | Selective Serotonin Reuptake Inhibitor (SSRI) |

| Onset of Action | Typically 1-4 weeks for noticeable improvement, with full effects potentially taking 4-6 weeks. | Typically 1-4 weeks for noticeable improvement, with full effects potentially taking 4-6 weeks. |
| Duration | Taken once daily due to its half-life, providing sustained effect over 24 hours. | Taken once daily due to its half-life, providing sustained effect over 24 hours. |

| Cost (Generic) | Generally affordable as a generic. | Generally affordable as a generic, often slightly less expensive than escitalopram. |
| When to Choose | Often preferred for GAD or if a lower dose is desired for similar efficacy, or if citalopram causes intolerable side effects at effective doses. | Often a first-line choice for MDD, especially if cost is a primary concern or if escitalopram is not tolerated. |
Bottom Line
Escitalopram is essentially a purified, more potent version of citalopram, meaning a lower dose of escitalopram can achieve similar effects to a higher dose of citalopram. While both are effective SSRIs for depression, escitalopram has an additional indication for GAD and may have a slightly better tolerability profile regarding cardiac effects at equivalent therapeutic doses. Your doctor will help determine which is best for your specific needs.
