How long does Citalopram/Celexa stay in your system?

Citalopram/Celexa can stay in your system for up to 10-14 days, if you have been taking it for a while, but when someone has just started taking citalopram, it will usually stay in your system for only about 35 hours. How long a drug stays in one’s system depends on its half-life, and the half-life of citalopram is around 35 hours.

Celexa is the brand name for Citalopram, which is an antidepressant prescribed for various mental disorders.

However, others suggest this depends on many factors such as how much and how often you have taken the drug, your metabolic rate, your age and overall health, body mass, etc.

It is believed the half-life is around 35 hours meaning it takes 35 hours for the body to get rid of the 50% of the drug.

If the factors mentioned are taken into consideration, then it is considered that the drug takes 7 days to get out of your system (but it can take longer). 

In contrast, the indicated that the half-life is about 30% longer compared to other antidepressants on average.

There is why one of the major citalopram benefits is the prolonged effects of the body systems.

According to, they also agree that Celexa’s half-life is approximately 35 hours.

It means that when a new dose of citalopram is not delivered, it takes around 35 hours for half of it to be removed from the person’s system.

This way, the concentration of citalopram in the body falls below 1% in approximately 8 days.

The feelings when the drug wears off may sometimes be unpleasant.

SSRI medication, in particular, short half-lives, may result in a withdrawal syndrome. This is considered one of Citalopram’s side effects.

There is a high probability of manifesting relapses for anxiety and depression, as well as possible flu-like symptoms, fatigue, and restlessness.

The half-life of Citalopram determines how long does it stay in your body, mostly.

It is believed that on average, as we discussed initially, Citalopram leaves the body within 10-14 days after the last dose was taken.

However, it doesn’t mean that there are no traces left in the body. There could be traces in the hair follicle, blood, urine, and saliva at the same rate. 

In the case of hair follicles and urine, the remainder of the substance can stay for a long time after the effects of the medication ceases.

Hence, Citalopram can still be detected by specific means after it’s cleared from the blood circulatory system.

How Long Does Celexa Stay In Blood?

It is said that Celexa 40 mg tablets, have a peak blood level that occurs in about 4 hours after intake.

In addition, traces of the drug can be detected in the circulatory system from 4 to 5 days after the last dose was ingested.

How Long Does Celexa Stay In Urine?

After the last dose intake, up to 50% of Citalopram can still be detected in the urinary tract system 9-10 days later.

If someone is preparing for a drug screening, it is important to inform the person performing the test known about your treatment with Celexa, since citalopram, being amphetamine, has a low potential for showing up on urine tests.

How Long Does Celexa Stay In Saliva?

Citalopram can be detected in the saliva approx. 8 days after the last tablet was ingested. 

How Long Does Celexa Stay In Hair?

According to “hair growth is powered by blood, and it is natural that hair follicles absorb any substances that are present in the bloodstream.

Most medications can stay in the hair for up to 90 days.”

Are there any factors that can slow down/speed up the removal Of Citalopram From The Body?

There are some factors that can interfere with the time that it takes for Citalopram to get out of a person’s system.

It is considered that the half-life of Citalopram is only one of the many factors.

In addition, someone’s age, weight, and lifestyle can influence the rate at which the medicine is removed from the system.

Additional factors that influence the duration of the removal of citalopram are metabolism and for how long and how often the person takes Citalopram.

“For instance, the drug will remain in the circulatory system for longer if the patient has a slow metabolism. Similarly, elderly and sick individuals will experience the prolonged effects of Celexa. Large body mass extends the period during which citalopram stays in the system as well. Therefore, drinking a lot of water and working out are some of the natural ways of how to get out Celexa from the system faster (”

However, it is important to consider that after the full elimination period, 80% has been eliminated through the liver and the remainder 20% by the kidney.

But, for the elderly or someone with hepatic or renal failure, it can take longer.

How long, how much, the time the drug should be taken and side effects can all vary from one person to the other as it is the case with any medication.

However,  it is important that medical professionals carefully consider all of these factors when designing a medication regimen for their patients.
