How much time will 10mg of methadone stay in my urine?

How much time will 10mg of methadone stay in my urine?

A week or more: methadone is a very long-acting drug and is very slowly metabolized. The parent drug can stick around for 5-10 days in urine after a single dose, and metabolites up to a week longer. If you are prescribed it for pain, you need a note from your doctor. If it is NOT prescribed, or you are in a safety-sensitive job (bus driver etc.) then you SHOULDN'T be taking it.

Urine (Definition)

Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more

I am on a pain contract with my doctor. I am on methadone and vicodine. Will he be able to tell if I have taken morphine? When he tests my urine will he be able to tell that I have taken some morphine?

The: The physician-patient relationship is based on a few important principles, the most important of which is probably trust. Pain management doctors often have the unenviable position of treating their patients with very potent, and therefore very habit forming, medications. Opioid pain relievers like methadone, morphine, and hydrocodone (found in vicodin) are examples of such medications. Because they are so potent, they are frequently misused or abused, stolen, traded or sold. Problems arise because these medications cause sleepiness and stun the part of the brain that keeps us breathing when we are asleep. These medications also interact with many other prescription drugs, and with recreational drugs including alcohol. More accidental deaths are caused by these sorts of drugs than by recreational drugs. Doctors who prescribe these drugs are monitored very closely by agencies including the dea and their state medical boards. Although they are often not responsible for unwanted outcomes from the use of opioid medications, they are often held professionally and legally accountable for them. Pain management doctors routinely ask their patients to sign a contract agreeing to take only the medications prescribed by that doctor and only according to the doctor's instructions. This is done for at least three reasons: 1) to protect the patient's life; 2) to not ruin the system for other patients (such as could happen if the doctor's dea license was suspended); and, 3) to protect the doctor from lawsuits and professional sanctions. Doctors frequently test their patients to make sure that the contract is being followed. These days, the test can be very, very accurate and very, very broad.

How long will methadone metabolites stay in stored urine?

How long will methadone metabolites stay in stored urine?

I don't know: I was able to find information about a lab which routinely does methadone drug testing.Their service keeps specimens for retesting for 30 days. I would presume that the tests would be accurate at least for that period of time. However, perhaps different tests/labs have different periods of time for which they ensure accuracy. Part of it would depend on how high the concentration of methadone is.

How long does methadone stay in your system? I have a urine test next wednesday.

Long time: Methadone is very fat soluble and stays in your fatty tissue for a long time. If you have been taking it chronically then it may still there is a good chance it will still be there next wednesday. The real question is why you have taken methadone. If you were taking it to get high, that is a very bad choice. Methadone will get you dead before it will get you high.

Do I have to take 2 urine tests one is a methadone and the other a drug panel if the dr didn't discuss them to me?

Drug Testing: Pain: Pain management allows a physician to demand regular screening for drugs, especially those they are prescribing. If you do not do the drug screening the physician has a right to stop prescribing the medications you are on.

I took 5mg of Methadone for the first time in 3 months. How long will it remain in my urine?

Not a good idea: Methadone is an opiate and is one of the most addictive substances that should only be taken with medical supervision. I really encourage you to think about why you took it and evaluate whether this is a bigger issue than how long it will stay in your system. I recommend you see a Mental health practitioner and or a substance use counsellor. Good luck to you.

Varies: Metrhadone half-life, the time it takes for half of the medication to be gone, is between eight (8) and 59 hours depending on many factors. It also depends what level of detection is being applied.

I been on methadone maint. Fr 17 yrs. I went from120 mg to 60 mg over few months. Now drug screen shows neg methadone and low metabolite. I take daily?

It happens: The presence of metabolite in urine is considered more reliable than methadone itself especially at lower doses. While the vast majority of patients will still have methadone detectable in urine after 24HRS, the situation you describe can happen. You can help improve reliability of urine results by avoiding coffee or excess water consumption before testing so that the sample is not dilute.
