Patients must take Effexor XR only under the medical supervision. Inform your doctor at once, if you have the following symptoms: aggravated depression, suicidal tendencies or behavioral changes.
How does the drug act?
Venlafaxine belongs to the group of antidepressant and anxiolytic drugs called serotonin and norepinephrine reuptake inhibitors (SNRIs). This drug is used for the treatment of depression. It affects the central nervous system (CNS) to improve mood in patients with depression.
Venlafaxine also treats anxiety, which can lead to the generalized anxiety disorder (GAD), social phobia, and even panic attacks. SNRIs acts by increasing the amount of certain chemicals known as serotonin and norepinephrine, which can be found in some parts of the brain.
Your condition may start to improve within 14 days of starting the treatment. However, it may take a few weeks to achieve the maximum effect.
Don’t stop the treatment without your doctor’s approval.
