As opposed to the occasional blues, depression is a real illness. Caused by an imbalance of the chemicals in the brain, mental health experts usually advise their patients to take antidepressants in addressing its symtoms. Antidepressants like fluoxetine prozac, which can be bought online at http://www.orderdrugs.ca/buy_fluoxetine.html, work to diminish the adverse effects of depression by righting the chemical imbalance occuring in the brain.

There are three major types of antidepressants recognized today: NDRIs(Noropinephrine and dopamine reuptake inhibitors), SSRIs like fluoxetine prozac(selective serotonin reuptake inhibitors), and SNRIs(Serotonin and Noropinephrine Reuptake Inhibitors). Since each of these antidepressants is formulated specifically to address specific issues surrounding depression, the effects are expected to vary accordingly.
