what is methadone half life

The half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. Hope that helps.

The half life of a chemical is the time it takes to break down become inactive. If the halflife is 10 hours then in 10 hours half the substance will be out of your system...in 10 more hours half of that..whick would be 25% would be left ..then in 10 more hrs 12.5 and so on . Hope it helps.

Finally to answer the question of why methadone takes longer is exactly this. If the methadone dose is Decreased 1 - 3 mg every 3 - 5 days you will come off with ZERO withdrawal. So depending on how low or high the daily mg dose is it will take a few weeks to years to go all the way down to 0 mgs a day. Only you know your dose so I'll let you do the math.

Even the taste is unbearable now. Probably cause i anticipate the throwing up. It is horrible. Its turned into a nightmare I'm hoping that this week when i see the Dr. that he will switch me back onto the methadone I'm insisting on it. Not another day not another week.... I often will not take it for several days at a time because of it. Than when i do I kinda feel that I'm having withdrawal symptoms. Legs restless and leg pain. Actually ya serious withdrawal issues going on.

I think this is interesting but the only part of this that is relevant to someone getting off dope is that drugs with a long half life - like suboxone and methadone - take longer to get off your receptors and because of that are associated with longer more severe withdrawals. I don't know the exact half life of morphine but it is relatively short compared to the others I mentioned. I know this is more of an answer than you bargained for but c'mon, you learned something right?

Hmmm....I don't personaly think that "Suboxone" is a "miricle" med. It isn't nothing more than Buprenorphine + Naloxone.Buprenorphine is derivative of thebaine and it just has effect on Mu receptors on synapse that is in our brain placed where the opoid receptors are.Now the facts and my expirience: Buprenophine,is BY ITSELF an half opoid because it is on and derivative of poppy as other real opoids are.

half life refers to how long the drug stays in your system. Some drugs have a longer half life than others. google half life and methadone and then goole half life of perocet or vicoden.

did you quit both the percs and methadone or are you still taking the methadone? I ask because methadone has a long half-life so it could be a few days before you enter full-blown withdrawal. Please - as mentioned earlier, talk to your Dr. again. Going cold turkey off these meds is NEVER advised. Please keep posting and let us know how you're doing.

I came off sub and back onto perc just to get of sub and quit ct from there after a while. Subs half life is the problem, its in your system a long time. a 32mg dose is active for 22 days. Theres alot of info for you to look up. The probelm is everyone got put on it for maintenace and high dose for too long. The trick to sub is a fast taper 10-15-21 days max and getting the dose down low as possible immediately. Lets put it this way i quit a 120mg oc habit c/t basically..

The half life of methadone is 36 hours. A person on methadone should wait up to 72 hours before taking the sub. It depends how long it takes a person to get the methadone out of their system. Everyone metabolizes the stuff at different rates. Generally, they shold score at least 25 on the COWS sheet, which is simply indicators on how far along into withdrawal you are. The longer the better. Close to or in full withdrawal is best.

It should be used with caution, under a doctors care (also be wary of doctors recommending long term use). There is a member on here who has detoxed off both methadone and suboxone in his life and Ill reacch out to him and ask him to respond to this post. On the right side of the screen you will see "health pages" click on that and look up members experiences with suboxone to give yourself a better idea of what your dealing with.

Apart from that, the dosage of the drug, its quality, and period and potency play an important role during the drug test. Urine test reveals positive result for 1-7 days. The half-life of drug is just 24-36 hours, and it may remain in your system from 7 hours to 52 hours. Half-life refers to the time taken to eliminate half of the drug’s effect; A drug takes 4-5 half lives to get expelled out of your system completely.

both methadone and sub/due to the long half life/ can have brutal wds if u ever want to get off of the drug/u r basically going to another narcotic but often people need this time to work on their issues/triggers///but neither drug will make u clean..u gotta do the work to make urself clean....neither will cause a whole lot of problems if used short term/21 days or less...thing is the physical part is the easy part ...the mental part later on causes relapse...have u ever tried any aftercare???

Are you saying that you only took one dose of Methadone? If that is what I read, something does not sound right. After years of this, haven't you seen a cardiologist? You really should. You need to get to the bottom of this. If I am interpreting this wrong, please correct me.

What is Methadone?: Methadone is an opiate that was first introduced after World War II as an alternative to morphine. Methadone was originally thought to be less addictive because of its extremely long half life. Today, methadone is used as an analgesic for pain management and more popularly as replacement therapy for heroin and other opiate addictions. Methadone is a cheap alternative to other opiate based medications which outweighs it potency when prescribing.

It has a very long half life, though I can't give you specifics. The dose and how long you were on it does factor in. Your doctor should be able to help you with your questions on this.

Nothing is normal when it comes to addiction. I'm no expert on Methadone, but I know it has a long half-life so be prepared for anything. I wish you the best. nauty..............

If people give in to sugar cravings and eat too many donuts whilst on methadone then it is the donuts that have caused the weight gain not the methadone. I am aware that many people gain weight on methadone maintenance but discipline, regular exercise and a healthy diet will eliminate the possibility of picking up excess weight.

Can you tell me what milligram dosage suboxone he will prescribe for a 30 mg per day methadone user. Suboxone is very expensive & if I need more than 8mg per day I can't afford it in addition to the cost of the dr. visits.

I never liked benzos, but it makes since. L-Tyrosine is the precursor to seratonin, which helps regulate your mood. I feel nutrition has to do with many of our common mental disorders in America. As you know methadone is another animal. The Thomas Recipe is a great tool. I took A LOT more meth than you do, but the nutrients seem to cut the symptoms in half for me. Tapering is the best way to go, in my opinion, due to the long half life of meth.

I have been given a spot in a detox...yay! I am on 27.5mgs of methadone daily at the moment and have been advised to reduce to 20mgs prior to detox beginning in 10days. I am relieved that the bupe is the way my detox is being approached as I have heard that coming off methadone is "one hundred and fifty times worse than hanging out from heroin".? I would reaaally appreciate some advice on what I might expect in detox, switching from methadone to the bupe from day 1...

My choice wud be detox hunny, Only coz i have been in this game for the last 18 years. I went on a methadone programm 9 - 10 years ago. it was only ment to be a short trem thing. But guess what yep i'm still on it & it's going to take me a long long time to get of the dose i'm on. Ye i no methadone can be very good & it do's do the job. But you have to be strong. Like you said you don't wanna go from 1 habit to another.

It will be 10x worse than any hydro etc w/d AND you will feel awful. I don't think u will make it to work because methadone has a half life that last for right at 3 days so your day 3 is the worse takes about week on done for bad w/d good luck to you. I am a methadone user and my bf detox from it and went through pure he!!

Thanks gnarls, not worried about being dropped for using methadone for psych reasons, I really am a recovering Oxy addict so that's all good, it's just that the methadone did something that not even being high on an 80 did, it makes me...dammit for lack of a better word "smooth". When I was high I was obviously manic, stoned, out of control, but on methadone I am a little hyper but that is my personality! There is no mania, and no depression, just me,,, a consistent me.

I have no experience but have read on here about countless members battling to get off of it. It has a much longer half life than the oxy (stays in your body) and is one of the hardest drugs to detox from. When I c/t two months ago I was on a similar dose of oxy as you. It is doable. As you mentioned, there are many different cases and answers when it comes to opiate detox. Arm yourself with as much knowledge as possible. Only you can decide what is right for you.

It has an extremely long half life, meaning 24 -36 hours after you take a dose, you STILL have half of the previous dose still in your system. Taking more methadone only worsens this half life effect, and can result in both cardiac rhythm problems and respiratory stoppage. Do NOT take any more methadone than you are supposed to be taking. If I were you, I would call my doctor and ask him what to do until you see him.
