Note: Keep in mind that these drugs are all serotonergic agents and clones or “copy cat” drugs of Prozac – the first SSRI antidepressant introduced to the market in America. Basically what applies to one, applies to the others. For instance we have more data out on Prozac because it has been around longer, but as the mode of action is the same for all of these meds the effects will be the same for the other drugs on this list as it is for Prozac. If we are discussing one drug, similar effects would be expected from any other company’s version of the drug. In fact it would be more honest to give them the titles of Prozac #1, Prozac #2,Prozac #3, etc. rather than the brand names they have been given, from the second clone, Zoloft, to the latest Prozac clone, Celexa.
