The length of time that Suboxone stays in a person's system depends on several factors, including the individual's metabolism, the dosage taken, and the frequency of use. Generally, Suboxone (buprenorphine and naloxone) can be detected in urine for up to four days after the last dose. In some cases, it may be detectable for up to a week. The drug can also be detected in hair for up to 90 days. It should be noted that detection times may vary and that it's best to consult a healthcare provider for more specific information.
Suboxone is a prescription medication used to treat opioid addiction. It is a combination of buprenorphine and naloxone. Buprenorphine is an opioid that works by attaching to specific proteins (opioid receptors) in the brain and spinal cord, blocking other opioids from attaching there. Naloxone blocks receptors in areas of the brain that control breathing, resulting in mild sedation when taken at very high doses—but naloxone does not produce euphoria or cause physical dependence like other opioids to do; neither does buprenorphine when combined with naloxone as it used for treatment purposes.
Suboxone is most often prescribed for people addicted to heroin or prescription painkillers but want help quitting these drugs without withdrawal symptoms (which can include nausea and vomiting, muscle aches and pains, and insomnia). However, because it contains two drugs (buprenorphine and naloxone), Suboxone can be abused just like any other opioid drug—and while there aren't many statistics on how common this type of abuse may be yet since Subutex became available over-the-counter three years ago (as opposed to being prescribed only through healthcare professionals), we do know that anywhere between 80% - 90% of people who use it recreationally take too much at one time due simply because they don't realize how quickly their bodies metabolize these medications compared with someone who was receiving them medically under supervision would take them over time instead.
