The Food and Drug Administration (FDA) classifies Quillivant as a controlled substance (CII) because it is a CNS stimulant. These types of stimulants are highly addictive and can easily cause dependence over long periods of time. It is against the law to give or sell Quillivant XR unless it is prescribed by a medical doctor.
Quillivant XR falls into the broad category of CNS stimulants, which include amphetamines, methylphenidate, atomoxetine, armodafinil and modafinil. Quillivant uses methylphenidate as its active ingredient. Other medications that also use methylphenidate include Ritalin and Concerta, though the dosage levels, strength and method of delivery differ between the medications. Because Quillivant is a stimulant, it is highly addictive, and individuals can develop a dependency on it over time.

Quillivant XR works by inhibiting the reuptake of certain neurotransmitters (dopamine and norepinephrine) in the brain. This increases the levels of these chemicals in the body, which in turn boosts concentration and lowers appetite. This is one reason why Quillivant is great at treating disorders like ADHD and narcolepsy, though its close relation to amphetamines makes it highly addictive and more likely to be misused.
The half-life of Quillivant XR is roughly five hours. This fast half-life means that most the drug is out of the body within one to two days. It also means that patients often feel side effects from the drug within hours of ingestion, and it only works for short periods of time. If you are thinking about quitting Quillivant, it is recommended to gradually taper off the drug instead of stopping all at once. Abruptly quitting Quillivant can result in intense withdrawal symptoms while gradually stopping can alleviate withdrawals and give the body time to adjust to functioning without the medication.
The amount of time Quillivant remains in your system depends on several different factors, including age, genetics, kidney function, how long you have been taking the drug and the dosage level. Your body can develop a tolerance to the drug if taken over an extended amount of time, which also can affect how quickly you eliminate it. In general, you can expect most Quillivant to leave your system within one to two days. Withdrawal symptoms, however, can linger for up to a few weeks. Fortunately, gradually tapering off the drug will help alleviate some of these symptoms. Always check with your doctor before stopping Quillivant.
Quillivant XR will only stay in your urine for one to two days, depending on your overall health and how long you have been taking the medication. After two days, the likelihood of Quillivant showing up in urine tests is minimal. Quillivant can stay in the blood for longer than urine, though any measurable amount should be gone with a week after your last dose. Drugs typically stay in hair longer than in urine and blood. You may be able to detect levels of Quillivant in your hair for up to one month after quitting.
