Methadone Facts

  • In blind trials, users who were given both drugs orally were unable to distinguish between the effects heroin and methadone.
  • Withdrawal from heroin should be over after seven to ten days. Withdrawal from methadone though, can take up to a month or even longer.
  • Many former heroin users have claimed that the horrors of heroin withdrawal were far less painful and difficult than withdrawal from methadone.
  • Methadone is a synthetic drug. It was first invented in Germany during the Second World War by scientists who, having discovered pethidine some years earlier, were developing other similar compounds.
  • The effects of methadone last longer than those of morphine-based drugs.
  • Methadone's effects can last up to 24 hours.
  • Deaths occur more frequently at the beginning of treatment in methadone programs; they are usually a cause of excessive doses (i.e. erroneously estimated tolerance).
  • Methadone generally entails the entire spectrum of opioid side effects, including the development of tolerance and physical and psychological dependence.
  • Individuals are as physically dependent on methadone as they were to heroin or other opiates, such as Oxycotin or Vicodin.
  • The most common side effects of Methadone are: drowsiness; lightheadedness, weakness, euphoria, dry mouth, urinary retention, constipation, and slow or troubled breathing.
  • Ironically, methadone used to control narcotic addiction is frequently encountered on the illicit market and has been associated with a number of overdose deaths.
  • Methadone comes as tablets, dispersible tablets, liquid, and liquid concentrate.
  • Methadone is one of the most difficult drugs to detox from since its effects are long-lasting and it is readily stored in the body's tissue.
