I forgot to take 40 mg prozac two days in a row and a day 4 days ago. Is this bad? Should I take it now or wait for the morning?
Prozac has a half life of like 9 days or something right? I should be OK right?
I guess I'll find out soon enough. LOL

Prozac will last in the body for 3 days then you wont feel the effect much.
Thats from my experinece.

you'll be fine, just pick up where you left off and don't triple the next dose.
Seldom.
Ps. I do that all the time. You gotta love that long prozac half life!

Prozac has such long half-life, that even if you stop taking it for a week, it (or rather its active metabolites) will still be acting inside your body.
Personally, i take it 3 times a week.

Really? that sounds perfect. When prozac first came out only in 20mg and I took it three days lst felt great 2nd anxiety, 3rd panic all day. So ditched it and my pdoc said you had such a remarkable response to it please take it every three days? I refused. Wonder what would happen if did it again since anxiety is worse now? Phillipa

Something relevant that i found:
Weekly dosing
Administration of Prozac Weekly once weekly results in increased fluctuation between peak and trough concentrations of fluoxetine and norfluoxetine compared with once-daily dosing [for fluoxetine: 24% (daily) to 164% (weekly) and for norfluoxetine: 17% (daily) to 43% (weekly)]. Plasma concentrations may not necessarily be predictive of clinical response. Peak concentrations from once-weekly doses of Prozac Weekly capsules of fluoxetine are in the range of the average concentration for 20-mg once-daily dosing. Average trough concentrations are 76% lower for fluoxetine and 47% lower for norfluoxetine than the concentrations maintained by 20-mg once-daily dosing. Average steady-state concentrations of either once-daily or once-weekly dosing are in relative proportion to the total dose administered. Average steady-state fluoxetine concentrations are approximately 50% lower following the once-weekly regimen compared with the once-daily regimen.
Cmax for fluoxetine following the 90-mg dose was approximately 1.7-fold higher than the Cmax value for the established 20-mg once-daily regimen following transition the next day to the once-weekly regimen. In contrast, when the first 90-mg once-weekly dose and the last 20-mg once-daily dose were separated by 1 week, Cmax values were similar. Also, there was a transient increase in the average steady-state concentrations of fluoxetine observed following transition the next day to the once-weekly regimen. From a pharmacokinetic perspective, it may be better to separate the first 90-mg weekly dose and the last 20-mg once-daily dose by 1 week (see DOSAGE AND ADMINISTRATION).
