Venlafaxine works by preventing serotonin and noradrenaline from being reabsorbed back into the nerve cells in the brain. This helps prolong the mood lightening effect of any released serotonin and noradrenaline. In this way, venlafaxine helps relieve depression. It is also helpful for relieving depression that is accompanied by anxiety. Effexor XL is additionally licensed to treat generalised anxiety disorder, which is a chronic disorder also thought to result from disturbances in the activity of noradrenaline and serotonin in the brain.
