Generic Effexor XR 75 mg (Venlafaxine XR) treats depression by affecting chemical messengers within the brain. These chemical messengers are called neurotransmitters, and some examples are serotonin, dopamine, and norepinephrine. Neurotransmitters are manufactured by nerve cells and are released by the cells. The neurotransmitters travel to nearby nerve cells and cause the cells to become more or less active.

Many experts believe that an imbalance in these neurotransmitters is the cause of depression and also may play a role in anxiety. Generic Effexor XR 75 mg , Venlafaxine is believed to work by inhibiting the release or affecting the action of these neurotransmitters.
