What is methadone?
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.
Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use opioid medicine with alcohol,
or with other drugs that cause drowsiness or slow your breathing.
Methadone may cause a life-threatening heart rhythm disorder.
Call your doctor at once if you have a headache with chest pain and severe dizziness,
and fast or pounding heartbeats. Your heart function may need to be checked during treatment.
