How long does Suboxone stay in your System

Suboxone is basically a combination of naloxone and buprenorphine. It is a medication for opioid addiction. An opioid is a sort of narcotic. Suboxone blocks its impact on the body and reduces his pain or feelings that lead to such addiction. It is not used as a pain medication instead; it is used to treat opiate addiction. It was basically developed for the treatment of heroin addiction. Suboxone reduces the craving of an individual for a particular drug. It stays for some time in the body before flushing out with feces and urine. This article will discuss how long does suboxone stay in your system.

How long does suboxone stay in your system and how it is metabolized?

The buprenorphine ingredient of suboxone remains in the blood stream for a longer time than the opioids. It has a longer elimination half-life. The elimination half-life basically refers to the time that the half of a single dose of any sort of drug takes to leave the body. The elimination half-life for buprenorphine is 37 hours which means that it takes about 9 hours for suboxone to remain in the body and I can be detected in that particular time.

How long does suboxone stay in your system?

Suboxone has two parts-buprenorphine and naloxone. Both of them metabolize differently in the entire body.

  • Naloxone

The short half-life of naloxone lies between 30 to 60 minutes. Naloxone alone is actually enough for treating the overdose of opioid. It stops this emergency situation for a short period of time. It will work until it is present in the body. Once it leaves the body, the remaining opioids present in the brain will bind again to the opioid receptors and the relapse of the overdose symptoms would occur.

  • Buprenorphine

Buprenorphine has the longer half-life than the naloxone. This drug would produce a number of metabolites that would remain in the system for about five weeks. This medication works best for the opioid treatment due to the following reasons:

  1. It is considered as the partial opioid agonist.
  2. It binds to the same opioid receptors in the brain.
  3. It reduces pain.
  4. Ease the anxiety and craving of an individual for a particular drug.
  5. Reduces the withdrawal symptoms of opioid.

The buprenorphine has a half-life of 38 hours which means that relapse of the opioid would not occur even after the nine days of leaving the suboxone. Therefore, only 50 percent of the buprenorphine would be metabolized after the two days of withdrawing while the naloxone would have gone just after few hours.

Factors influencing how long does suboxone stay in your system

There are a large number of factors that affect the stay of suboxone in the body. These factors include:

  • Age

As the metabolic rate slow down with the age, so the suboxone would also metabolize at a slower rate. This longer half-life of buprenorphine is due to the health problem, medication or lower physical activities.

  • Height and weight.

The body fat has a great influence on the stay of suboxone. If an individual takes a greater dose of suboxone than the body mass, then it would remain there for a longer period. Moroever the suboxone is considered to be lipophilic, so it will store in the fats, lipids, and tissues of the system.

  • Urinary pH

The urinary pH of an individual influences the stay of suboxone in the system. An individual who has acidic urine would take lesser time to eliminate suboxone than the one who has alkaline urine.

  • Dosage

The suboxone dose affects its stay in the system. The heavier dose an individual take, the longer it would stay in the body. Contrary, the lower dose an individual takes, the lesser time it would stay in the body.

  • Metabolism

Metabolic rate greatly influences the speed at which the suboxone leaves the system. The metabolism of an individual who has greater physical activities would be faster than the one with lower physical activities. Suboxone will immediately leave the body if metabolic rate is higher.

  • Health of the liver.

If an individual suffers from any sort of hepatic disease then the half-life of buprenorphine would also prolong and it would take longer to leave the system. Generally, the more severe liver disease, the longer it will take to eliminate with feces or urine.

How long does suboxone stay in blood?


As the suboxone metabolize in the liver, it forms different metabolites that remain in the blood for a longer period of time more than the drug itself. Blood tests are somewhat the most common sorts of tests and they can detect the suboxone shortly after taking it. Moreover, it detects the buprenorphine to some extent as well. The most appropriate time for getting the evidence of a drug would be the short time after the dose. This time should not be greater than the 2 hours.

How long does suboxone stay in the saliva?

How long does suboxone stay in the saliva

Saliva tests are also commonly used, as they are simpler to administer. These tests usually work for just a few days or less than a week after the recent dose of such drug.

How long does suboxone stay in the urine?


Urine tests are one of the most common tests. The buprenorphine would easily be detected in the urine just in 50 minutes after the consumption of suboxone. Moreover, the heavy dose would be detected in 2 to 4 days after the consumption. However, this time-limit may vary with the metabolic rate, the higher the metabolism the more instantly drug would remove from the body.

How long does suboxone stay in hairs?

How long does suboxone stay in hairs

Suboxone would also stay in hair follicles and can be detected for about 2 months after the consumption. Yet, this is not the reliable form of test.

These above certain points explain how long does suboxone stay in your system. This system includes drug tests regarding urine, blood, hairs, and saliva, as there is a greater probability of suboxone to stay in these parts of the body.
