Methadone is an opioid medication. An opioid is sometimes called a narcotic.
Methadone reduces withdrawal symptoms in people addicted to heroin or other narcotic drugs without causing the “high” associated with the drug addiction.
Methadone is used as a pain reliever and as part of drug addiction detoxification and maintenance programs. It is available only from a certified pharmacy.
You should not use methadone if you have severe asthma or breathing problems, or a blockage in your stomach or intestines.
Methadone can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
