How long would it take for 5mg of Prozac (fluoxetine) to leave my system if I've been taking it for 5 weeks?
Prozac (fluoxetine): Is sometimes used on a temporary basis to minimize the affects of coming off other SSRI agents (yes there are SSRI withdrawal symptoms) Prozac (fluoxetine) is typically given in the 10-20 mg dose for this purpose for a 7-14 days.

Started Prozac (fluoxetine) 2 months ago. Weight up about 2 lbs with no lifestyle change. Heart, kidney, liver ok. Is this probably Prozac (fluoxetine)? Or normal variation?
Not necessarily: When people are depressed they frequently have poor appetite and lose weight. So it stands to reason when their treatment (in this case the effect of Prozac (fluoxetine)) begins to work they may regain their appetite and start to gain weight. There are other potential reasons for gaining weight so this should be a topic of discussion with your doctor. ...Read more
Up to 5 wks: It is difficult to determine the exact duration prozac will stay in the system, because people metabolize prozac at different rates. The longest it would probably stay in the system is 5 wks, (this is the "safe" washout time when there is no risk for drug interaction with MAO inhibitors.). Prozac has a half life of 7-9 days (pretty large margin there). but that does not mean it is out in 14-18 d. ...Read more
Less than a week: The usual starting dose for fluoxetine (Prozac) is 20 mg, so you were on a VERY low dose, so after 6 doses there is not very much med in your body. The time for 1/2 the medicine to be eliminated from the body in a healthy person is 3 days at most, so it would take about 6 days for the last dose to be completely eliminated. It may be gone sooner depending on how quickly your liver metabolizes it. ...Read more

I took 20mg of Prozac (fluoxetine) for 4 days. I have been off of it for 3 days. How long does it take to get out of my system?
A while: Since you took prozac/fluoxetine for only 4 days, it should leave your system in about 1 - 2 weeks completely. In general, if someone has been taking Prozac for a while (longer than two weeks), it can take up to 5 weeks to completely wash it out of ones system. For side effects (or beneficial effects) to go away, Prozac does not have to wash out completely, just be low enough to not affect you. ...Read more
Prozac (fluoxetine): The time to onset of action of an antidepressant, including prozac, (fluoxetine) depends upon a number of factors including the condition being treated. That being said, you can generally expect one to two weeks to start to notice the clinical effect and 4-6 weeks to safely evaluate the full effect of any particular dose in the treatment of depression. Side effects, if present, can be experienced sooner. ...Read more
I only took it for 3 days, so how long will it stay in my system. Prozac (fluoxetine) 20 mg. Also can I safely take my tramadol?
Prozac (fluoxetine): Prozac (fluoxetine)'s half life is up to 6-7 days but if you only took 3 doses, you didn't get much into you system. Trauma sol interacts with Prozac (fluoxetine) like drugs. It can increase the risk for the serotonin syndrome. If you are off Prozac (fluoxetine) 3 days you should be able to take tramadol. It is unlikely it would occur at your dose and duration ...Read more

I took 20mg of Prozac (fluoxetine) for 4 days I have been off of it for 6 days How long does it take to get out of my system? I've had heart palpitations all day
About a week: There's 2 related questions here. It takes about a week for fluoxetine (prozac) to leave the body after dosing has stopped. This is longer than other antidepressants. But all antidepressants, including prozac, continue to have an effect on mood for 2-3 weeks after they're stopped. The brain effect persists a couple weeks even after the drug is gone. ...Read more

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
My dr. Lowered my dose of Prozac (fluoxetine) from 20mg to 10mg. Because of the half life does this mean I will have more in my system and if so for how long?
Took 400mg of sam -e for 10 days. How long does this stay in your system. Want to stop it and go back to 10mg of prozac (fluoxetine)?
Depression: You need to consult with your doctor as I have seen negative effects of going between sam-e and prozac (fluoxetine). Sam-e is difficult to assess as to its quality as it is not regulated. Be honest with your doctor as to your dose so you can make the adjustment with the least consequences. Best wishes. ...Read more
Been on Prozac (fluoxetine) for 5 days at 20mg. Doc said to stop. How long before leaves my system?
Prozac (fluoxetine) elimination: Prozac has an elimination half-life of 70 hours, with its active metabolite (norfluoxetine) at 330 hours. That means it will take 70 x 5 = 350 hours (or a little over 2 weeks) for fluoxetine to be gone from your system. It will take much, much longer for norfluoxetine to be eliminated also. ...Read more

Tried lamictal as mood stabilizer was up to 50 mg at 3 weeks with intense itching my md told me to quit it today and raised my Prozac (fluoxetine) from 10 mg to 20mg how long will it take for itching to stop?
Lamictal & itch?: lamictal can cause a rash (SJS) that may be severe enough 2 b fatal. More common, any new med can cause a benign, but annoying rash (sometimes preceded by itch). bc there is a small chance that lamictal may cause the dangerous rash, MDs wisely stop the med if ANY new rash (or rash-like sx) develops. When will it pass? Us. days. Best way 2 know is have a dermatologist biopsy - 2 determine if SJS ...Read more
