Methadone may be habit-forming. You may have withdrawal symptoms when you stop using methadone after using it over a long period of time. Do not stop using methadone suddenly without first talking to your doctor. You may need to gradually reduce the dose.

•

Your doctor may recommend that methadone be given to you by a family member or other caregiver. This is to make sure you are using the medicine as it was prescribed as part of your treatment. It is important to use methadone regularly to get the most benefit.

Do not use more methadone than prescribed if you feel that the medicine is not working properly. Call your doctor if your symptoms do not improve while using methadone.
