This all depends on your height, weight, and dosage. The half life (the time it takes the medication to become half effective) is 24-48 hours. It could take as long a 1-4 weeks for it to completely clear your system.

3-5 days

  • The length of time any drug (illicit or prescribed) stays in your system will vary. In large part, it depends on your physiological makeup (e.g., your physical height, weight, your amount of body fat, your age, current state of health, whether or not you exercise mildly-aggressively-or at all). Whether or not you are undergoing any degree of stress (i.e., your "state of mind") at the time you ingest drugs can play a part as well.
  • Still other considerations include your "frequency" of use (1x per day? 3-5x per day?), the "quantity" of drug you used each time, and the "length of time" (days? weeks? months?) of your consistent drug-use prior to your drug test. Even the quality ("potency") of the drug you ingest determines "how long" the drug is detectable in your system when your urine is analyzed (tested) at the lab.
  • However, for most people, detectable levels (i.e., shows up as a "positive" in a laboratory drug test) of the following drugs stay in the body for these approximate periods of time.
  • Methadone, 1-7 days.
  • Depends on use. one time -3 days. maintenance use - 1 week.
  • As for adequate dosing and effects approx. 24 hours , after that withdrawal symptoms appear as for drug testing I could estimate it not appearing on specific methadone test after 5-10 days of abstinence.
  • I have been on methadone for almost 3 years and from what I've been told methadone has a "half life" of 24 hours... meaning 1/2 the methadone is in your system for 24 hours. So for example, someone who's only taken one dose of methadone, say 50 mg.

Day 1: 50 mg. (Day they took it).

Day 2: 25 mg.

Day 3: 12.5 mg.

Day 4: 6.25 mg.

Day 5: 3.12 mg.

Day 6: 1.56

Day 7: .78

***Generally once you get below 1/2 mg. it doesn't show up.

However, for someone like me who takes methadone daily, and has, for a long period of time, it would take longer. Even if someone took it a week it'd be much longer.

Example:

Day 1: 50 mg. (Day you took it)

Day 2: 25 mg. from original dose. PLUS: Additional 50 mg.

Day 3: 12.5 from original dose, 25 from 2nd dose. PLUS: 50 mg.

Day 4: 6.25 from original, 12.5 from 2nd, 25 from 3rd. PLUS: 50 mg.

Day 5: 3.12 from original, 6.25 from 2nd, 12.5 from 3rd, PLUS: 50 mg.

Day 6: 1.56 from original, 3.12 from 2nd, 6.25 from 3rd, 25 from 4th, PLUS: 50

Day 7: .78 from 1st, 1.56 from 2nd, 3.12 from 3rd, 12.5 from 4th, 25 from 5th, PLUS: 50
aproximately 9 days i think i read
I am asking you
Not too long about a couple of days max but that depends on how many days you're on it for
Methadone can remain in the body around 3 to 5 days depending on your metabolism.
depends on use

one time -3 days

maintenance use - 1 week
two to 5 days and it should be out drink alot of water
Depending on how frequently you use methadone, about 1-2 weeks for an occasional user. Now of course the side effects of methadone can last much longer and this is from personal experience. (everyones body metabolizes methadone at different rates but expect at least a week)

Methadone is a very long acting sythetic opiate and will usually always take a while for it to fully clear out of your system even if only used once.
Opiates, which is what methadone is, usually take about 3 days to leave your system. Hair will however, hold traces for much longer.

How long will 30 milligrams of methadone stay in my system for?

for about 24-48 hours, it depends on your tolerance...if you have a low tolerance, yeah, but if you tolerance to methadone (or even other opiates) is high it, more than likely 1 day.....if you're asking how long methadone stays in your system, about 3-5 days, but you have to have a special drug test to detect methadone, and most Dr.'s or whoever does not test for methadone because it if too expensive for the testing for methadone rather than a regular drug test. Hope that helps ya!
