Ritalin (the brand name for methylphenidate hydrochloride) is a prescription stimulant medication used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy.
It works by stimulating your central nervous system, increasing the neurotransmitters dopamine and norepinephrine in your brain. It’s similar to other ADHD medications like Adderall and Concerta.
Ritalin is classified as a Schedule II controlled substance by the FDA and DEA. This means it has an approved medical use but also has a high potential for abuse.
Drug tests are administered for a variety of reasons including pre-employment checks, joining a sports team or organization, or for legal or medical reasons.
There are multiple drug tests that can be used to detect Ritalin in the body. Some are used more often than others and include:
- urine test: you give a sample of urine in a collection cup which is then tested for the presence of Ritalin and ritalinic acid, it’s metabolite or what it’s metabolized into in the liver
- blood test: a small amount of blood is taken from a vein and then used for drug testing
- saliva test: saliva is swabbed from your mouth and then tested for signs of Ritalin
- hair test: a strand of hair with the follicle is taken and tested for signs of drug use
Ritalin Detection Times
These different drug tests have different detection windows with some being longer than others. While one test can only detect it for a couple of hours, others can detect it for days after last use:
- urine test: can detect Ritalin 1-2 days after last use
- blood test: can detect Ritalin 12-24 hours after last use
- saliva test: can detect the drug 24 hours after last use
- hair follicle test: can detect Ritalin 90 days after last use
How Long Does Ritalin Last?
How long the drug lasts in your system depends on the half-life of Ritalin as well as a number of other factors. The average half-life of Ritalin is 1-5 hours with an average of 3.5 hours in adults.
This is considered a relatively short half-life and means that most of the drug will be out of your body within 2-10 hours.
This timeline can range depending on a number of factors including whether you take the immediate-release or extended-release formulations. Sometimes, it will take up to two days for the drug to fully leave your system
Factors That Affect Ritalin Detection Times
There are quite a few factors that affect how long Ritalin stays in your system as well as how long it can be detected in the body. The times we provided above are averages.
Factors that affect whether Ritalin is detected in your body for a shorter or longer period of time include:
- rate of metabolism
- age: older people eliminate the drug slower than younger people
- weight/body mass: those who are heavier eliminate the drug more quickly
- how physically active you are
- how often you take the substance
- how hydrated you are
- the dose you use: a high dose will last longer in the system than a small dose
- how you use or abuse the drug
- how long you’ve used it
- organ function
- use of other drugs and/or alcohol: when taken with alcohol, Ritalin will likely be eliminated slower than usual
