Please help, how much Prozac (fluoxetine) would it take to kill you?

Why do you need to. Know this bit of information? If you are having imminent thoughts of suicide please have a friend or relative take you to the nearest emergency room now. You can call 911 for transport if needed. If you are playing with the idea of suicide with no current plan or intent, then please see a psychiatrist and/ or a psychologist to get assistance. Let your family physician know as well.
