Seroquel (quetiapine) is a prescription antipsychotic medication commonly used to treat mental health conditions like bipolar disorder, schizophrenia, and depression. If you’re prescribed Seroquel, you might wonder, “How long does Seroquel stay in your system?” The answer varies depending on dosage, frequency of use, metabolism, and other individual factors. Additionally, you may ask, “Is Seroquel a controlled substance?“ While Seroquel is not classified as a controlled substance, it is still important to use it under medical supervision. This guide explores the half-life of Seroquel, how long it stays in your body, and ways to support its clearance.
How Long Does Seroquel Stay in Your System?
On average, Seroquel stays in the system for about 1 to 2 days after the last dose. However, certain factors can influence this timeline. The half-life of Seroquel is approximately 6 to 7 hours, meaning it takes this amount of time for half of the drug to be eliminated from your system.
What is the Half-Life of Seroquel?
The half-life of a drug refers to the time it takes for the concentration of the drug in the bloodstream to be reduced by 50%. For Seroquel, the half-life is around 6 to 7 hours. This means that after 6 to 7 hours, only half of the original dose remains in the bloodstream. It takes about 4 to 5 half-lives for a drug to be fully eliminated from the body, which is why Seroquel may stay in your system for 24 to 48 hours.
How Long Does Seroquel Stay in Your Urine, Blood, and Saliva?
- Urine: Seroquel can be detected in urine for up to 48 to 72 hours after the last dose.
- Blood: Seroquel is typically detectable in the blood for 24 to 48 hours.
- Saliva: Detection in saliva is similar to that in blood, with Seroquel remaining for around 1 to 2 days.
- Hair: While not commonly tested for, Seroquel could potentially be detected in hair for up to 90 days.
Factors That Affect How Long Seroquel Stays in Your System
Several factors can impact how long Seroquel remains in your system, including:
- Dosage
- Higher doses (like 200 mg, 300 mg, or 400 mg) take longer to leave the body than smaller doses like 25 mg or 50 mg.
- Frequency of Use
- If you take Seroquel daily, it may accumulate in your system, leading to a longer clearance time.
- Metabolism
- People with faster metabolisms eliminate drugs more quickly than those with slower metabolisms.
- Age and Health
- Older adults or those with liver or kidney issues may take longer to clear Seroquel from their system.
- Form of Seroquel
- Seroquel XR (extended-release) has a longer half-life than immediate-release versions, which means it stays in the system longer.
- Hydration and Activity
- Staying hydrated and engaging in physical activity can support the body’s natural detoxification processes.
How Long Does Seroquel 25 mg, 50 mg, and 100 mg Stay in Your System?
- 25 mg Seroquel: Typically stays in the system for 24 to 48 hours.
- 50 mg Seroquel: May take 24 to 48 hours to leave the system.
- 100 mg Seroquel: Could remain in the body for up to 2 days or slightly longer, depending on metabolism and other factors.
- 200 mg to 400 mg Seroquel: Higher doses like 200 mg or 400 mg take longer to eliminate, often requiring up to 48 to 72 hours.
How Long Does It Take for Seroquel to Leave Your System?
For most people, Seroquel is fully cleared from the system within 48 to 72 hours. This timeline can be affected by the factors mentioned earlier, such as dosage, metabolism, and overall health. People taking Seroquel XR (extended-release) may experience a longer elimination period.

How to Flush Seroquel Out of Your System
If you need to remove Seroquel from your system quickly, here are some tips to support natural detoxification:
- Stay Hydrated: Drink plenty of water to support kidney function and flush out waste.

- Consult Your Doctor: Do not stop taking Seroquel without medical guidance, as this could result in withdrawal symptoms.
How Long Does It Take for Seroquel to Wear Off?
The sedative effects of Seroquel are often felt within 30 minutes to 1 hour after taking it. These effects can last for 6 to 8 hours. However, for some people, grogginess or drowsiness may persist into the next day, especially with higher doses or extended-release forms.
How Long Does Seroquel Last in Your System for Drug Tests?
Seroquel is generally not included in standard drug tests for employment or legal purposes. However, it may be detectable in specialized tests for psychiatric medications. Here’s how long Seroquel can be detected:
- Urine Test: Detectable for 2 to 3 days.
- Blood Test: Detectable for 1 to 2 days.
- Saliva Test: Detectable for 24 to 48 hours.
- Hair Test: Detectable for up to 90 days, although hair testing is rare for this medication.
How Long Does Seroquel Last (Duration of Action)?
