What are the dangers and side effects of methadone use? We’ll explore all those questions here and invite your questions about methadone at the end.
How does methadone affect the brain and nervous system?
Methadone is a prescription drug used both to relieve moderate to severe pain and to help treat opioid dependence. Specifically, Methadone works by “occupying” the brain receptor sites affected by heroin and other opiates. The result is that methadone blocks the euphoric and sedating effects of opiates while relieving cravings and symptoms associated with withdrawal from opiates.
While highly debated, methadone potentially can cause a euphoric “high” when it binds to the opiate receptors of the brain. However, methadone high effects are less intense than other, similar medications. The decreased addiction liability for Methadone have made Methadone Maintenance Programs a popular form of addiction treatment since the 1960’s.
How does methadone work in the body?
Methadone is excreted slowly so it can be taken only once a day. So what are methadone’s effects on the body?
Methadone slows activity in the brain, and thereby, the body. As a central nervous system depressant, methadone can have some of the following effects:

- changes in menstrual periods
- decreased sexual desire or ability
- flushed or red skin
- loss of appetite
- mood changes
- impaired coordination
- shallow breathing
- slowed heart rate
- stomach pain

How long does methadone work?
Methadone’s effects can last anywhere from 24-36 hours, depending on the opioid tolerance of the individual. For pain management, it should be taken throughout the day as directed by a doctor. When used to help treat opiate and opioid withdrawal, it’s only given once a day.
What makes Methadone work better
Methadone works best when it’s taken in the doses prescribed by a doctor. Because it can take so long to notice the effects of the medication, it’s important not to assume it “isn’t working” and take more for pain management purposed – this can easily cause an overdose and even death.
Does Methadone work for everyone?
No, methadone is not right for everyone. When taken as prescribed, methadone is safe and effective. But all medicines have risks. The physical effects of methadone must be managed in order to get the maximum benefits of the medication.
