- Bunavail is a combination formulation of buprenorphine and naloxone, used only for OUD
- Bunavail has a unique route of administration: a double-sided strip that sticks to the inside of the cheek
- Bunavail, like other medications, is not a stand-alone treatment for OUD. It is only a part of an overall treatment plan.
- Bunavail has abuse potential
- Bunavail has proven effectiveness as part of a comprehensive treatment plan for OUD
Bunavail combines buprenorphine and naloxone. It is an option used for treating withdrawal and cravings in people with opioid use disorder.
Bunavail is one of many medications for treating the withdrawal symptoms and drug cravings that occur during detox and early recovery from opioid use disorder (OUD). Bunavail is used in medically-assisted detox.
Bunavail, like other medications used to assist people in recovery from addiction, is not a stand-alone treatment for addiction. Bunavail is a part of an overall comprehensive treatment program for the complex challenges presented by addiction.
What is Bunavail?
Buprenorphine is an opioid that has pharmacological properties that make it well suited for opioid replacement therapy:
- It displaces other opioids from their receptors in the brain and blocks other opioids from attaching
- It has low opioid activity (it is a partial opioid agonist), so it causes very little euphoria and has a low risk of overdose
- It has a long half-life, so it can be dosed every other day or twice weekly
- It has a “ceiling effect,” meaning its negative effects max out and don’t increase with further use
Naloxone, the other active ingredient in Bunavail, is the perfect addition to buprenorphine. It is an opioid blocker (opioid antagonist). It prevents attempts at abusing opioids by blocking the effects of opioids.
Although there are other pharmaceutical buprenorphine-naloxone combinations available, Bunavail is unique in that it comes as a small, thin strip that dissolves when it is applied to the inside of the cheek, inside the mouth. Bunavail strips are bi-layered with the medication side and a backing to prevent swallowing the medication. It is the only buprenorphine product that has this feature.
Bunavail Approval by FDA
Bunavail vs. Suboxone
Bunavail and Suboxone both contain the same two medications but have slightly different delivery systems. Suboxone comes in a tablet that dissolves under the tongue.
Because of how the Bunavail strip distributed medication, Bunavail gets more medication into the bloodstream and less swallowed than Suboxone does. This factor is important because buprenorphine does not work well when swallowed.
How to Take Bunavail
The manufacturer provides detailed guidance on how to take a Bunavail strip. The recipient wets the inside of the cheek with the tongue, then applies the side with the active ingredients (which is marked with BN2, BN4 or BN6) to the wetted area and holds it in place for 5 seconds. The strip sticks upon contact.
The backing prevents any of the drug from being swallowed, ensuring that it is nearly all absorbed into the blood. The Bunavail film dissolves completely, so there is no residual film to remove afterward.
The Bunavail strip is easy to apply with a fingertip and it stays in place. People can talk while the medication dissolves and the strip has a “citrus blend” flavor.
How Long Does Bunavail Take to Dissolve?
Bunavail comes in three strengths that each take a different amount of time to dissolve. However, according to the manufacturer, each should completely dissolve within 15 to 30 minutes. People should not eat or drink until the strip is completely dissolved.
Bunavail Treatment for Opioid Dependence
Does Bunavail block opiates? Yes, Bunavail works for treating OUD withdrawal by blocking opiate and opioid receptors, preventing other opioids from having any effect and preventing the brain from experiencing the shock of sudden withdrawal.
Who Should Take Bunavail?
According to the Bunavail prescribing information from the FDA, Bunavail should be used for the treatment of OUD in adults over the age of 18. Bunavail is intended for use as part of a comprehensive opioid addiction treatment regimen and should not be used as a stand-alone therapy.

Bunavail is well suited to outpatient and office-based management, which makes it an especially useful option for people who are receiving outpatient treatment or are following discharge from a residential or inpatient rehab program.
Who Should Avoid Bunavail?
Bunavail should not be used for pain management; some buprenorphine medications are used for treating pain, but Bunavail is appropriate only for the treatment of OUD.
Bunavail side effects may be magnified and have serious or even fatal consequences if taken together with benzodiazepines or other central nervous system depressants, including alcohol. People taking Bunavail should be forthcoming with their prescriber about their medications and consider the following:
- People with impaired liver function should not take Bunavail unless cleared by their physician
- Bunavail should not be used during pregnancy or in women who may become pregnant It also should not be used by women who are breastfeeding
- Bunavail should not be used by children
- Bunavail should not be started until withdrawal effects from opioid use have started, or a prescribed amount of time has passed since the last dose

How Long Does Bunavail Block Opiates?
How long does it take for Bunavail to kick in? Bunavail may precipitate withdrawal symptoms quickly when it is started too early because of naloxone’s rapid onset of action. However, buprenorphine, which relieves withdrawal symptoms, takes three to four hours to reach peak levels in the blood.
How long does Bunavail last? The two active ingredients in Bunavail have different half-lives:
It takes six to seven half-lives for a drug to be generally eliminated from the body, with buprenorphine taking three to five days until its levels are low enough to start causing withdrawal symptoms.
Bunavail Side Effects
Side effects vary from person to person and may diminish over time. Common side effects of Bunavail may include:
- Withdrawal symptoms
- Low energy, lethargy or fatigue
- Low blood pressure
People should not operate machinery or drive until they see how Bunavail affects them.
Despite being only a partial opioid agonist, Bunavail may produce a high. People who have been using opioids usually do not feel any high because of their high tolerance, but the Bunavail high is usually noticeable for those who don’t regularly use opioids.
As with any opioid, some people may try to figure out how to abuse Bunavail, and an overdose may occur. Some symptoms of a Bunavail overdose are:
- Pinpoint pupils
- Sedation, loss of consciousness, coma
- Low blood pressure
- Respiratory depression (slow, shallow breathing, or not breathing at all)
The risk of an overdose occurring is reduced in Bunavail because of the presence of naloxone and because of buprenorphine’s ceiling effect. However, an overdose is possible in opioid-naive individuals who take Bunavail, people who try injecting Bunavail or in people who take large doses of opioids to try to overcome the opioid blocking effects of Bunavail.
Bunavail Effectiveness for Opiate Addiction Recovery
Buprenorphine is superior to methadone for tolerability (i.e., people are more likely to remain on buprenorphine than they are on methadone). One study showed that buprenorphine is associated with a one-year retention rate of 75% (in a recovery program) and 75% passed urine drug tests, compared to 0% on both measures in people taking a placebo.
Other studies have shown that buprenorphine is highly effective, and has been associated with:
- Reduced mortality
- Reduced relapse rates
- Reduced HIV and Hepatitis C transmission rates
- Improved outcomes in pregnancy
- Improved retention within recovery programs
- Improved quality of life.
The combination of buprenorphine and naloxone, such as in the Bunavail medication, has been shown to offer the same benefits as buprenorphine alone, but with the added benefit of further reducing abuse potential or relapse. Additionally, the Bunavail buccal film delivery system has demonstrated improved uptake of the drug and reduced swallowing compared to other oral delivery systems.
