How long how after Fentanyl patch off can you take suboxone?

The American Addiction Centers recommend waiting at least 12 to 24 hours after your last dose of fentanyl before taking buprenorphine (Suboxone). However, some people may need to wait longer, such as those who have been taking high doses of fentanyl or who have other medical conditions. Therefore, always consult a doctor before starting buprenorphine to discuss the best timing for you.
