Does xanax raise serotonin levels?

hi yes,most drugs like benzo's do just the opposite of making brain chemicals..

Severe depression may result from biochemical changes in the brain induced by benzodiazepines. Benzodiazepines are known to decrease the activity of serotonin and norepinephrine (noradrenaline), neurotransmitters believed to be closely involved in depression. Antidepressant drugs including the selective serotonin reuptake inhibitors (SSRIs such as Prozac) are thought to act by increasing the activity of such neurotransmitters.

Take care.-
