How Long Does Methadone Stay In Your System?

Different drugs stay in our system for different amounts of time, depending on the type of drug that you are using. However, even the same drug will leave different people at different rates. The time that a drug will stay in your system depends on your physical make up, (height, weight, tolerance, fat percentage and health) as well as some physiological factors. Stress or other mental factors could alter the timeline as well.
Methadone has a half-life of twenty six to thirty six hours, meaning that after a day and a half at least half the methadone in your system will be gone, while the other half will be gone in another day and a half and so on. As such, depending on the factors mentioned above as well as the level of the dose you have taken, Methadone can keep affecting you from seven hours to three days. However, like many drugs it is also detectable after the drug has stopped working on you and in fact you may have to wait four or five half lives before it is undetectable in a drug test. This means that a drug may be detectable for up to a week.
Again, it should be remembered that there is no exact rule for how long Methadone will keep affecting you or stay in your system, and you should consider your dosage and tolerance for Methadone before making any conclusions. Finally, anyone hoping to be sure that Methadone is out of their system by a certain date should try to stop use at least two weeks before, hydrate well, eat healthily and exercise as much as possible.

I have been taking suboxone prescribed by a doctor. There they told me that when doing a drug test that tests the amount in your system, that we all have traces in our system, of a lot of drugs. I know that for methadone, people are allowed 300mg before they consider it to be a positive. And we are allowed 150 mg for cocaine, and 50 mg for pot, and so on. I personally had around 50 mg of methadone in my system, and I don't do them. However, the neighbor came by and asked me if I would do one with him, and I gave my self maybe a third of a 10 mg pill. I am going to the doctor in a couple of days, and was curious if that few mg would show up stronger, or would it just add on to that 50 that I showed up in my system. The doctor said that the reason we were allowed to have some in our system is because people flush them down the toilet and the water company doesn't treat the water for drugs. Basically, we all have a little bit of drugs in our system, if we drink water. So, do you think that a third of a methadone mixed with a third of a half of a Valium will show up as a positive on a drug test?

I took 60mg of methadone on thursday and 90mg on wednesday. These were the only two times I have taken it. Tomorrow which is monday I have a drug test, any idea how long it will take to not show up in my system?

I have been taking methaodone for at least seven years, but I only take five mg's a day and I stopped taking them all together about a month ago, I just wanted to know how long it will be in my system?

Hi can I ask you a question?? Did you wean off the 70mg before leaving the clinic or leave while you were still on 70mg?? I go to a clinic and I've tried coming down.. Once I went from 110mg to 0mg in 3 weeks and that was hell!! I couldn't stand it after a few days and had to check back in. So I was just wondering if you left there at 70mg and if you had any withdraw symptoms? Thanks!

I know that just taking one 10mg pill a week stays in your system for 3 - 5 days.  So in your case it will probably will take at least three weeks to a month depending on how long you were taking it.

I am undergoing outpatient rehab and am taking Suboxone for pain pill addiction. I took however before I started rehab, methadone for about 6 days prior, 3  10 mg pills a day. I have been in rehab for 3 weeks and it is still showing up in my urine...

I would think 3 days just like opiates, but hmmm I do not know if I would bet on it. I do although believe you are going to the family doctor for a scrip due to the detox symptoms..... Why did you stop the clinic? Send a private e-mail to me if you wish I just wonder if you made it or not!

My doctor has me on 60mgs of methadome a day but I don't take them like she wants me to. I take it as needed, I don't want to take that much, now she is analysing a urine test how do I pass that? Can someone help me.

7-10 days. Your withdrawal is going to be awful. And more than likely you'll feel withdrawal symptoms long after the 7-10 days. I would get some clonidine , benzos, and something over the counter for your stomach. It's extremely difficult to get through the wd w/out taking a different type of opiate.

Traces of Methadone can stay in your system up for 60-90 days. Even though the effects of the medication may have worn off, the evidence that you took it will linger in the system.
