Venlafaxine vs. Escitalopram (Lexapro)

Major depressive disorder

Escitalopram is at least as effective as venlafaxine XR and significantly better tolerated 8. Escitalopram has a faster onset of antidepressant effects 9.

Side effects

Escitalopram appears to be significantly better tolerated than venlafaxine XR 8.

Withdrawal symptoms

Venlafaxine is associated with significantly higher rate of discontinuation symptoms than escitalopram 8, 9.

Cost
Escitalopram provides a more cost-effective first-line treatment of depression than generic venlafaxine XR 4.

Venlafaxine vs. Mirtazapine (Remeron)

Major depressive disorder

Mirtazapine and venlafaxine are similarly effective for the treatment of overall symptoms of depression, and both antidepressants may be useful for somatic (bodily) symptoms of depression 12. Mirtazapine appears to have higher response and remission rates than venlafaxine 1.

Mirtazapine orally disintegrating tablets (ODT) have a faster onset of antidepressant efficacy than venlafaxine XR 3.

Side effects

Mirtazapine is associated with significantly fewer dropouts due to adverse events 1.

Venlafaxine vs. Trazodone (Desyrel)

Major depressive disorder

Venlafaxine can produce more improvement in the cognitive disturbance and retardation factors on the Hamilton Rating Scale for Depression. Trazodone is more effective against the sleep disturbance factor 6. Trazodone efficiency in comparison to venlafaxine is faster, so trazodone is characterized by potentially quicker beginning of activity in patients with depression disorders 5.

Side effects

Venlafaxine is most likely to cause nausea, whereas trazodone is associated with the most dizziness and somnolence 6. Libido decrease is common side effect with venlafaxine treatment 5.
