How long after stopping Suboxone does someone have to wait before narcotic painkillers become effective?
It depends. It depends on how high of a dose of suboxone the person was taking per day. A small amount may take one or two days and a higher dose maybe longer. You should know that taking suboxone over time tends to reduce one's tolerance for narcotic painkillers. A person who has been on suboxone may take their usual high dose of painkillers and quit breathing because they thought they could handle it & die.
Depends. The answer varies upon the individual's physiology and body habitus.
