Been on prozac (fluoxetine) since a kid now an adult who cants maintain an erection. And puberty stopped when I started the pro zac is there a correlation?

Hmmm...not sure: Don't know that I'd agree that Prozac (fluoxetine) STOPPED you from entering or completing puberty exactly but I definitely agree that it very well could be a major contributing cause or even the reason for your erectile dysfunction.

How long does a higher dose of Prozac (fluoxetine) start to get into your system. (Went from 50-60 since Friday)?

Several days: Within 3-5 days I'd expect the higher dose to be stabilizing in your bloodstream. Whether or not that translates into clinical effects for the purpose your doctor prescribed it though is a different story since there may be much more lag time for the body to RESPOND to a medication or its increase than, for the substance to actually get to measurably higher/stable levels. Make sense? ...Read more

When tapering to stop prozac, (fluoxetine) what is the lowest dose taken? Currently at 2.4mg daily and if I skip a dose I still get lightheaded several hours later

Talk to doctor: Prozac (fluoxetine) also comes in concentrate (liquid) form. You could in theory get a 1 mg dose that way. However, your dose now is very low. Lightheadedness could also be underlying anxiety symptom recurring. Best to hold the dose and take daily until you review with prescribing doctor, who needs to monitor any dose changes. I hope this helps. Best wishes. ...Read more
