Switching from 60mg prozac for 4 mnths to zoloft (sertraline). Will I switch right over? Take both concurrent for awhile? Taper then start?

Prozac to Zoloft (sertraline) Prozac can stay in your system up to 72 hours, so under supervision of your doctor, it is possible to discontinue Prozac & start low dose Zoloft (sertraline) at 50mg. daily then upgrade the dose every 3 days as tolerated.
