How long does Ritalin stay in your system?

Ritalin doesn’t stay in the body for very long. The drug’s half-life is 3 hours at the most, meaning that Ritalin leaves the body within a few days.  Can Ritalin show up on a drug test? NO, not on a standard 5 panel, but  Ritalin can show up positive for a drug screen panel for amphetamines.  Further, drug detection times can depend on a number of factors – how the drug was taken, how often a person takes the drug, and the person’s body time and metabolism. We review here and invite your questions about Ritalin in the system at the end.

Main Ritalin uses

Ritalin is used to treat ADHD in adults and children. It contains methylphenidate, a stimulant medication. Paradoxically, Ritalin has a calming, focusing effect in people with ADHD. However, in those without the condition, Ritalin can cause agitation and restlessness.  And people who get high on Ritalin abuse it for its euphoric effect.

How do you take Ritalin?

Ritalin comes in an immediate, sustained, and extended release tablet. Although Ritalin is intended to be taken orally, some people abuse Ritalin by crushing the pills and then snorting them. Snorting Ritalin is very dangerous, particularly with the sustained and extended release.

Peak levels and half life of Ritalin

The peak levels and half life of Ritalin depend on the formulation. But with the immediate release version of Ritalin, methylphenidate reaches peak levels in the blood in about 2 hours. And methylphenidate from Ritalin tablets is eliminated from plasma with an average half-life of about 3.5 hours. As a comparison, in children the average half-life of methylphenidate is about 2.5 hours, with a range of about 1.5 – 5.0 hours.

Ritalin drug testing: How long does Ritalin stay in the body?

Because of how quickly Ritalin is metabolized, it doesn’t stay in the body for very long. Even the extended and sustained release formulas should clear a person’s system within a few days of being taken. Ritalin can still be tested for and detected in the system using a variety of methods, including blood, urine and hair sample drug tests.

How long does Ritalin stay in blood?

Because of its relatively short half life, Ritalin does not stay in the blood more than a day. After 24 hours, a urine test might be more accurate.

How long does Ritalin stay in hair?

Ritalin can be detected in hair for at least 90 days. However, the detection window for hair samples depends on the length of someone’s hair and the amount of the drug they’ve taken. Heavy or extended use will be easier to detect in hair screens for Ritalin than occasional use.

How long does Ritalin stay in urine?

Ritalin can be detected in urine for 1-2 days after dosing. Ritalin will be detectable slightly longer if you’ve taken the sustained or extended release version of the drug, simply because not all of the medication is released with the initial dose. Sometimes Ritalin methylphenidate metabolites can linger in the body longer depending on factors like weight or body mass.

Ritalin and addiction

Ritalin is addictive when it is not used for a legitimate medical purpose. Addicts can develop a tolerance to Ritalin, and start taking more Ritalin achieve euphoric side effects. This can lead to withdrawal and can increase the risk of overdose.

Problems with Ritalin?

If you struggle with Ritalin addiction, please see a doctor for help. There may be therapies which can help you quit taking Ritalin. Being open with friends and family about your struggles with Ritalin will help you build a support network that can help keep you accountable.

Hello Alison. What does your doctor say about this issue? Ritalin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

I took 10mg in one yesterday, and 20mg in today. Is that enough to show in a drug test trough a hair sample that is going to be taken in about a month from today?

8:30 am April 5th, 2012

Hi Will. To be honest, I’m not sure. I do know that chronic amphetamine use shows up during hair analyses 90 days previous to the test itself. But if you’re talking about one time, low dose use…I’m really not sure. Can you report the use in advance of he test in the interest of transparency and face the possible consequences?

I want the methylphedidate to show up on a drug test so if i took only one 10 mg methylphedidate at 8 am and was tested at 2:00 pm. the same day will it show up on that urine test?

9:22 am May 24th, 2012

Hi Larry. If you are using Ritalin as prescribed, and have been tested by your doctor’s office or your employer, methylphenidate will show up under expected min and max cutoff levels. Why do you need methylphenidate to show up on the urine analysis?

Jennifer

My son & I both take 10 mg Ritalin twice a day. The doctor done a urine screen on us to check for it on our system. The screen came back negitive. We take the medication everyday as directed. I don’t understand why it didn’t show up in the urin screen. The bottle reads methylphenidate 10 mg tablet. Can you help

12:16 pm June 1st, 2012

Hi Jennifer. That sounds strange. Do you take any other medications which might interfere with the drug screen results?

Kathy

Hi I took 27 mg er Ritalin prescribed and showed up negative…took it at noon then had blood at around 4pm. I am on tons of meds for chronic illnesses and had my urine show up negative before. What is going on?? So weird. Blood and urine negative.??

11:02 am September 22nd, 2012

Hi Kathy. I’d suggest that you take a list of your current prescriptions to the Medical Review Officer in charge of drug testing. It’s possible that the other medications are interfering with methylphenidate and creating a false negative test. Request a re-test.

I am prescribed 20mg sr 4x a day, I generally remember to take 1-2 a day … eitherr way i take them everyday and have only been on them for about 2 months they have improved life greatly,however i have to be tested every two weeks (urine test) for my doctor. i have been tested a total of 3x and all 3 came back negitive . I’m confused as to why they keep being negitive .. i also take 7 other meds a day , metaphormin , vitamin b, vitamin d, daposone, tecta, norlutate, and singular… could these other meds be affecting the results?

2:20 pm October 17th, 2012

Hi Elisha. I wonder if your doctor is testing not for the presence of Ritalin, but for the exact dosage you SHOULD be taking? Sometimes people will get a Ritalin RX and then sell it to others. Your doctor might suspect that you are not taking Ritalin as prescribed (which you aren’t) and then stop treating you. So, take all your Ritalin as you should, and at the very least…tell your doctor about the exact doses you’ve been taking.

Elisha
3:28 pm October 17th, 2012

he is only testing for presence of Ritalin not how much and i honestly forget to take the others a day … however im working on a plan so i wont forget them anymore…but with that aside i do take them everyday so im unsure as to why i am testing negitive and other then a urine test is there any other way he could test… oh he also checks for a narcotic which im prescribed that always shows but not the other. thanks for the advise

12:46 pm October 18th, 2012

Hi again, Elisha. Certain prescribed and over-the-counter medications and foods might generate false negative results for different substances. False negatives might also result from laboratory error. I’d check in with your doctor again and request a retest. Also, ask if ANY metabolites were shown as a result of the test, or if the test came back with NO sign of amphetamines. It’s always possible that your sample was mixed up with someone else’s!

hi i took a small snort of ritalin aproxamatly 4days ago im on the methadone programme and they have asked me to go in for a urine drug screening tomorow. will the ritalin be cleared out by tomorrow?it is the first time ive taken ritalin in years and it was only a small lineof a 20mg pill!! your help would be much appriciated!!

9:37 am November 27th, 2012

Hi alexisnz. If you are taking a urinalysis, it’s possible that Ritalin would have cleared your system before the drug screen five days later. And most methadone maintenance programs are screening for opiates, rather than amphetamines. But you might feel better if you disclose the use to your prescribing doctors. It’s really a decision you alone can make.

Alison

I have stopped taking my ritalin 20mg 3x per day because I am trying to get pregnant but life these past 5 months is overwhelming and I am so unfocused that I am getting very little done. I also have depression and have changed all my meds. I currently only take a prenatal vitamin and welbutrin 100SR, I was taking omega 3′s but ran out about a month ago and although it’s on my to do list it has yet to be restocked. I guess my question is this if I start taking the ritalin again and stop as soon as I find out I am pregnant what would the half life of that be? I would start by taking 10mg 2x per day and I would of course be taking the first response early detection pregnancy test so that I can stop the ritalin as soon as I have a positive pregnancy test. I have been told by 1 doctor that this is a good plan and another that I should not take the ritalin if I want to get pregnant. I Just need some clarification on the half life, so that I can make a decision and move forward. Thank you

2:56 pm January 26th, 2013

Hi Alison, I certainly don’t argue you doctor’s advice; however, I took Ritalin before and during both of my pregnancies without issue. Both of my girls were healthy, as was I. We had to stay in hospital for the babies to be monitored after birth, just to be sure they weren’t experiencing withdrawal. For that reason, a paediatrician was consulted, and everything was fine. I cannot function without Ritalin, as I take it for Narcolepsy, so stopping was not an option. My girls were, obviously, not breastfed. I was informed that this would make them hyperactive, anorexic, insomniacs. Best of luck to you!

I Take generic Methylphenidate 36 MG ER with 5 MG regular Methylphenidate 8, Noon and 4 and have been since May 2012. I need to pass a urine drug test and they test for everything, I am 5′ 5″ tall and weigh 155 my metabolish is slow to normal. How long before the test do I need to stop taking my medicine? Is there a way to speed up any traces of it in my system? Thank you – I really want this job – I have ADD and needed medicine for school.

2:36 pm January 29th, 2013

Hi Sara. IF you’re taking methylphenidate as prescribed, it may show up on a DOT 5 panel drug screen as an amphetamine, but as long as your levels are within therapeutic use, the Medical Review Officer will return the drug screen as NEGATIVE for abuse. Just present the prescription to the laboratory. You should be fine.

It’s amazing how Americans have given up their rights. The fourth amendment guards against unreasonable searches and seizures. Taking something from the inside of someones body is definitely a search and seizure.
When did it become the norm that we need permission from the government to do almost anything. If we think something will help us we should as free men and women be fee to do it. The government should only interfere if we are infringing on someone else s rights.
With the furture of DNA testing etc. it’s time for people to DEMAND their privacy be protected, including their body fluids.

I heard that Injecting any sort of prescription drug is dangerous and can lead to infections due to the substance not being specifically made for this purpose. Does anyone else feel extremely nauseas when taking Ritalin on an empty stomach? Also, if I take 15mg of Ritalin (short acting) at 11:00am and drink alcohol at 6:00pm, will I have to worry about possible unwanted drug interaction? I only got prescribed Ritalin a couple weeks ago, so I don’t yet know the effects of taking Ritalin and drinking Alcohol on the same day.

Please answer this question and email me with the answer. I admittingly did abuse ritalin the night before a drug test given to me by my pain management doctor, I snorted about 50 20mg pills and was given the drug test the very next day, so I’m worried the doctors will know I abused it, so my question is simple, will the drug test which is sent to a lab show that I abused my ritalin? Please let me know if ritalin is something which will be tested for in a urine test sent to a lab? Please be as detailed as possible and what should my excuse be if they do indeed find that I had a high level of it in my system, I would be very grateful for any answers or advise you can give me. Thank you, sincerely Paul

Ivana @ Addiction Blog
9:03 am September 19th, 2014

Hi Paul. Overall, yes, Ritalin can be detected in a drug test. But, it depends on the test itself and on what urine is being tested for. Ritalin is detected in a intense Urine testing stage, on the kinds of tests usually conducted in the military. Also it depends how fast your body gets rid of it during the day so that’s another reason why it can’t be detected in the common urine tests today. So, I think you’ll be fine, and for more info you can read this article: http://prescription-drug.addictionblog.org/does-ritalin-show-up-on-a-drug-test/

I’m prescribed 20mg ritalin 3x day. I messed up and went on a small binge and snorted like 4 days worth.My dr tested me before and I was negative. Dr was pissed. Now I’m not sure if I get tested in 2 days if my levels will be ok. I will not be able to take them for 2 days to get the count right since they do pill counts. I have a friend who gets the daytrana patch [20mg] and she gave me a few. Will wearing them 2 at a time make my levels ok? I’ve never done this before and am scared that I will get busted by dr for abuse. I really normally take them right but had some dumb thinking and messed up.
