Effexor was approved for the treatment of depression in 1993. Effexor increases the levels of both serotonin and norepinephrine (two neurotransmitters though to cause the symptoms of depression) in the brain.
Effexor's latest approval is for the treatment of anxiety disorder. It is estimated that 95% of people with depression experience at least one symptom of anxiety, including excessive or uncontrollable worry, apprehension, irritability, and muscle tension. Studies suggest that co-morbid depression and anxiety may have an impact on a patient's social functioning and is associated with a 30% to 60% increase in the utilization of healthcare services.
Some of the side effects of Effexor include the following:
Effexor affects various neuro chemicals in the body which are responsible for nervous system regulation. It inhibits specifically norepinephrine and serotonin reuptake, and also weakly inhibits dopamine reuptake. The net result is more neuro chemicals circulating in the nervous system.
