Question: how long do you have to wait to take suboxone?
Answer: Before you take your first dose, wait at least: 12 hours since you last used a short-acting opioid (fentanyl, heroin, crushed OxyContin, Percocet). 24 hours since you last used a long-acting opioid (OxyContin taken orally, Hydromorph Contin, OxyNeo). 72 hours since you last used methadone.
