Switching antidepressants zoloft to prozac because of results of genetic testing .. is this good choice .. 8 weeks on sertraline with minimal help on ?

SSRI's/genetics: Not sure what "genetic testing" would indicate a "switch to Prozac instead of Zoloft". Prozac and Zoloft belong to the same pharmacologic family (SSRI's). The problem with Prozac is the time it takes to achieve a therapeutic dose (15 days or so), and it takes the same amount of time to get off Prozac. Lexapro (also an SSRI) has a shorter half-life, and is easier to change if problems occur.
