About Methadone

How It Works...

Methadone works on parts of the brain and spinal cord to block the "high" caused by using opiates (such as heroin). It also helps reduce cravings and withdrawal symptoms caused by opiate use. The action of methadone is similar to other synthetic (man-made) medicines in the morphine category (opioids). Substances that are derived directly from the opium plant (such as heroin, morphine, and codeine) are known as opiates.

Why It Is Used

Methadone is commonly used to treat addiction to opiates (such as heroin). Taken once a day, methadone eases opiate withdrawal for 24 to 36 hours, decreasing the chance of relapse.

How Well It Works

As a treatment for opiate addiction, methadone reduces the cravings and withdrawal symptoms caused by opiate use by blocking the "high" and preventing the intense euphoric rush of these drugs. This effect allows people to avoid the physical and psychological highs and lows caused by changing levels of opiates in the blood, decreasing the chance of relapse. In some cases of opiate addiction, methadone treatment may be needed for several years or longer.

What To Think About

Methadone is a long-acting medicine, and each dose stays in the body for a long time. For this reason, dosages should be adjusted with caution, ideally by an addiction specialist. It may take a couple of days after the medicine is started before the dose of methadone is fully effective.

Checkups

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
