Easily find out how long does fluoxetine stay in your system. Enter a dose, or see a demo.
This fluoxetine metabolism calculator is an easy tool to determine the amount of substance left in your system. It does so by looking at the elimination half life.
Use it to keep constant levels of fluoxetine in the body, or avoid unwanted interactions between substances.
Try a demo to get an idea of how it works. Or enter your data as follows:
You can add unlimited ingestions to track multiple drugs or repeating doses of the same one.
Once you enter the required data for at least one ingestion, the graph shows the results:
Hover on the graph to get a precise amount of drug left at any time.
You can consider the drug eliminated when about 97% of it is gone. That's when most drugs no longer have any effect.
A drug's half life is an estimate of time it takes the amount of drug in the body to reduce by half. Now that you know the drug half life definition, let's continue to the exciting stuff!
Half life of fluoxetine in the body is 5 days.
If you took 200 mg of fluoxetine:
Almost 97% of the drug is eliminated after 25 hours. This is usually enough to consider the drug's effects negligible.
As seen above, eliminating fluoxetine takes 4 to 5 half lives. Note that drug tests can detect the usage longer.
Doubling the dose increases the time to eliminate it by one half life.
After learning what does half life of a drug mean, let's look at how to use it.
Half life helps you evaluate how often to take the drug to maximize effects and minimize adverse reactions. You can maintain a minimum effective level of fluoxetine in the body by adjusting your doses or their frequency.
This is irreplaceable knowledge for tapering, titrating, or reaching a steady state.
When tapering, you gradually decrease the dose of medication to stop using it. Decrease it too quickly, and you experience withdrawals. But decrease it too slowly, and you suffer side effects unnecessarily long.
Titration increases the dose for maximum benefit without side effects.
The drug needs to remain at a constant level (be in a steady state) during treatment to produce the desired effect. It happens when you consume the same amount of drug that's eliminated from the body.
For all of the above, knowing how much of the drug is left in your body and how it compounds is necessary. With this knowledge, you quickly establish a dose and administration schedule.
And last but not least, you can limit drug interactions, as you know how much drug is left in the body at the time of the second administration. This helps preserve drug efficacy and avoid unwanted side effects.
We use the following formula to calculate fluoxetine half life:
The formula assumes exponential decay. The substance decreases by half over each interval, which equals its half-life. If the time is less than the offset, the remaining amount is considered 0.
But don't worry about the math, as calculating half life is simple with this fluoxetine drug test calculator.
Yes, fluoxetine half life in body varies depending on many factors:
Half life is used to estimate how long does medicine stay in your body. That means half of the drug is gone from your body 5 days after administration.
You can use it to find out how long is fluoxetine in your system.
That depends on how frequently you take it. It can start compounding if you take another dose before the last one is gone from your body.
You should wait at least 25.29 days to avoid build-up and possible harmful effects.
So, if you're wondering how long does fluoxetine stay in your system after one time use, the answer is approximately 25.29 days.
No. Half life is the time it takes half of the drug to be eliminated. Drug duration is the overall time the drug remains in the body.
