Summary
Methadone is used to treat pain and opioid dependence, which is a condition where a person is addicted to opioids. It helps manage pain and reduces withdrawal symptoms, which are the physical and mental effects that occur when a person stops using opioids.
Methadone works by binding to opioid receptors, which are parts of the brain that respond to pain signals. This changes how the brain perceives pain and helps reduce withdrawal symptoms, which are the effects experienced when stopping opioid use.
Methadone is usually taken once daily by mouth, which means swallowing a pill or liquid. The dose varies based on individual needs and the condition being treated. Doctors adjust the dose to manage symptoms effectively.
Common side effects of Methadone include constipation, which is difficulty in passing stools, nausea, which is feeling sick to the stomach, and drowsiness, which is feeling sleepy. These effects can vary in severity.
Methadone can cause respiratory depression, which is slowed breathing, and can be addictive. It should not be used by people with severe breathing problems or allergies to Methadone. Avoid alcohol and other sedatives, which can increase these risks.
