Avatar f tn The half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. Hope that helps.
738895 tn?1234654277 I think heroin has a half life of 4-8 hrs, and methadown 20-36hrs, i understand that it takes 36hrs for half the drug dose to leave your body, but theres only 2 day deference between the two drugs but methadown takes months to kick and heroin weeks. thats the part i dont understand but theres only 2 day deference between the two. anyone with knowledge please try in a laymen terms to explain. thanks for any help in advance.
Avatar f tn 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.
Avatar f tn And 40mg to 140mg is a huge jump,is a doctor prescribing you these meds? Also yes,methadone has a very very long half life,so it stays in your system a long time. In your fat cells,blood and bones. Not a good drug at all.
Avatar f tn theres no half life after 5 days
Avatar m tn i cant remember which but either avisg or worried has the chart in their jpurnals. i dont know a site for it though.
Avatar n tn You can google a narcotic conversion chart to see if the difference in dosage and medication is correct. You can also talk to your pharmacist about it. Methadone is very different from other narcotics. It's half life is much longer so it takes a while to get out of your system. It also stores in your muscle and bone, which also make it more difficult to come off.
Avatar m tn If you are still worried, I would look up the half life of 30 mg of methadone. To my knowledge Methadone is stronger longer acting than Oxycodone. Since you were not on it long that is the way I would decide.
1800740 tn?1324237171 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.
Avatar n tn but i do know sub has minimal pain relief...some but not as much as methadone..if it is a life time thing...and getting pain relief to lead a life with some sort of quality to it....that is a choice for u but the meth has more pain relief so i wish u well...
Avatar m tn Or just the Methadone and then 4 days off the Norco? It makes some sense to me. Methadone has a long half life as you know. But, it's not longer than 7 days right? Did you find something that says different? I'm sure you're nervous based on what you've read. Info from the internet is not science or always sound medical advice. Do your reading. You need to trust your doctor and if you have these questions, call him up. He works for you, Sweetie!
Avatar f tn So at the clinic I'm on 150, 3 40's 1 half a 40 and 1 quarter. Totaling 150 is that Mg of methadone? I'm kind of tripping. I used about 100-150 Mgs of codeine and sometimes about 200-400 of morphine daily. 5-7 roxy 30's and 2-4 morphine 100's a day. Now I've not touched a pill but I do take 150 methadone daily since February 6 of this year. Is this a horrible thing I'm doing or what?
Avatar f tn That being said, if you are doing this on your own, you are supposed to wait until you are in moderate withdrawals before you take it, or you will risk precipitated withdrawals. The half life of Methadone is long, and it is stored in your tissues and likes to hang on longer than other opiates. There is a scale called the COWS scale that might help you decide when to take your first dose. Good luck to you!
Avatar m tn Sub is a bear to withdraw from and very expensive for most. Methadone is also difficult/half life of both is similar and a long WD time for either drug.. Sub is not an efficient pain med by most standards, methadone is...one ro but I am not sure why u r on methadone. If u r going to a clinic, then it is expensive. If u see a doctor and he writes u a scrip for pain, it is dirt cheap. Since u said liquid, I wld think u go to a clinic.
6298176 tn?1380134459 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.
Avatar f tn I was at about 200mgs methadone and 8 mgs bupe was about right, which is half what my doctor prescribed, but that is 50mgs methadone to 1mg bupe, was still a little off, but stabilized in a couple days. I'll try to find another conversion chart, but that conversion you shared means that 1mg dupe is equal to 300mgs of methadone, maybe check your source again.
477746 tn?1254784547 However it still is active on similiar receptors in the brain as other opioids (which prevents feelings of withdrawal)? It also has an extremely long half-life in the body which equates to extremely long and difficult withdrawal when discontinued? And a final question, how does methadone compare to suboxone chemically? What makes it superior as an aid to opioid addiction? Just trying to understand things better...
Avatar f tn I need to know if abilify decreases methadone? Has anyone been on these two meds at the same time? Can you tell me how it made you feel? I was prescribed abilify but haven't started it yet because I am unsure of the interaction. Some say it causes withdrawal for the methadone and some say it increases methadone, talk about confusing!! Please tell me your experience or opinion.
Avatar f tn To determine how long the drug is likely to stay in your system after your last dose, it is necessary to consider Suboxone’s half-life, or more specifically, the half-lives of its active ingredients buprenorphine and naloxone. The half-life of buprenorphine is an estimated 37 hours, which is considered extremely long. It takes your body nearly 2 full days to excrete just 50% of the buprenorphine within a Suboxone dose.
862936 tn?1239553570 one 8 miligram sub is equal to 30 miligrams of methadone your right
Avatar f tn With the long half life of Methadone, it typically takes a little longer to get to that point, but like weaver said, everyone is different. You'd be much better off doing this in a sub clinic, under the supervision of a doc who can properly help calculate an appropriate induction dose. That's what I would recommend to you. Continue tapering on the Methadone until you can get in at a sub clinic. Best of luck, keep us posted!
Avatar f tn I remember when I was doing my bachelor of nursing learning about a link between long term opiate therapy causing weight gain for 2 reasons - odema (water retention) and metabolism slowing down. I remember methodone, due to both its super long half life and the fact that therapy of methodone is usually long them - being mentioned specifically.
Avatar f tn However, my story is this, First day I think the gave me an 8mg subutex and told me to take half in the morning and half at night. Well next day i took less than 4mgs day after that probablly 1mg, next day a .5, next day maybe .25, next day a crumb. I have felt little to no withdrawls. Just one night of a half night sleep and a little irrability....nothing to really complain about. I believe less is more.
Avatar f tn Start taking smaller doses??? and prolong the time between them. Make a chart and follow it. Methadone is a long lasting medication, so try going 8-12 hours between doses and cut the amount into half, then quarter every two days, then increase the time between to only at night so you can sleep for a few nights, cutting the dose even further. This should all take no more then a week.
Avatar m tn 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.
