How does Venlafaxine work?

Venlafaxine works by preventing the reuptake of epinephrine and serotonin by nerves after they have been released. Since uptake is a vital mechanism for eliminating released neurotransmitters. It also terminates their actions on adjacent nerves. The reduced uptake caused by this drug increases the effect of epinephrine and serotonin in the brain. 

This medication affects neurotransmitters. It is the chemicals that nerve within the brain make and release to communicate with one another. Neurotransmitters either travel across space between nerves, attach to receptors on the surface of nearby nerves.
