Methadone is a synthetic opioid agonist used for chronic pain and also for opioid dependence. It is used to treat chronic pain, and it is also used to treat addiction to heroin or other opioids.

Nausea, vomiting, constipation, lightheadedness, dizziness, dry mouth, drowsiness, or sweating may occur. Some of these side effects may decrease after you have been using this medication for a while.

You should not use methadone if you have severe asthma or breathing problems, or a blockage in your stomach or intestines. MISUSE OF METHADONE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Keep the medication in a place where others cannot get to it. Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
