It works by increasing certain kinds of activity in the brain. In animals, this drug has been shown to be an effective pain reliever. Studies evaluating venlafaxine for pain have shown that this drug may alter pain tolerance thresholds thereby providing a pain-relieving effect in headache or other conditions.
