Methadone is also sold as Dolophine. Methadone is part of a category called opioids. It was used to treat people with extreme pain. Today, your doctor may use it as part of your treatment for an addiction to heroin or narcotic painkillers. Methadone changes the way your brain and nervous system respond to pain so that you feel relief. Its effects are slower than those of other strong painkillers like morphine. It blocks the high you get from drugs like codeine, heroin, hydrocodone, morphine, and oxycodone.
It can also help if you’re in treatment for addiction to other opioids. It can give a similar feeling and prevent withdrawal symptoms. You may hear this called replacement therapy. Methadone replaces the opioids in your system with milder effects. If you use the drug for a long time, it might lead to lung and breathing problems. Even though the effects are milder than other opioids, your body can still adapt to it. This means that you’ll need to take more to feel the same relief from pain or withdrawal symptoms, which can lead to abuse and addiction. It can also change a woman’s menstrual cycle. If you get pregnant the chances of complication is higher.
