My grandma has copd, could she take methadone?

Narcotics have the potential of making a patients not be able to expire carbon dioxide which could be life threatening. If a patient has been on narcotics for a long time, the chance of this is less, if they are not increasing the dose.

Possibly: Any older person, especially with repsiratory medical issues, should be very careful with any medication that causes sedation and respiratory depression.
