Suboxone is a dissolvable film or tablet containing buprenorphine and naloxone, placed under the tongue or against the cheek to treat opioid use disorder. Using it correctly involves specific timing for your first dose, proper placement in your mouth, and ongoing oral care to protect your teeth. Here’s what you need to know at each stage.
Timing Your First Dose
The most important rule with Suboxone is this: you must be in moderate opioid withdrawal before taking your first dose. If you take it too soon after using opioids, the buprenorphine in Suboxone will displace the opioid molecules already sitting on your brain’s receptors. Because buprenorphine is a partial activator of those receptors (rather than a full one like heroin or fentanyl), this swap triggers a sudden, intense withdrawal called precipitated withdrawal. Symptoms can hit within 15 to 60 minutes and are often far worse than regular withdrawal.
How long you need to wait depends on which opioid you’ve been using:
- Short-acting opioids (heroin, hydrocodone, oxycodone immediate-release): 12 to 24 hours since your last dose
- Extended-release opioids (OxyContin, extended-release morphine): at least 36 hours
- Methadone: more than 48 hours
Your prescriber will assess your withdrawal using a standardized scoring tool. A score of 10 to 12 or higher on the Clinical Opiate Withdrawal Scale (COWS) signals that you’re ready for your first dose. Signs they’re looking for include goosebumps, yawning, restlessness, dilated pupils, and body aches. The goal is to confirm your body has cleared enough of the previous opioid that Suboxone can bind to receptors without causing that dangerous rebound.
How to Place the Film or Tablet
Suboxone works by absorbing through the tissue in your mouth, not through your stomach. If you swallow it like a regular pill, your body absorbs far less of the medication. Proper placement makes a real difference in how well it works.
For sublingual tablets, place the tablet under your tongue and let it dissolve completely. Do not cut, chew, or swallow it. If your dose requires more than two tablets, you can place them all under your tongue at once. If that’s uncomfortable, place two at a time and wait for them to dissolve before adding more. Keep each set under your tongue until it’s fully gone.
For sublingual film, the process is similar. Place the film flat under your tongue and let it dissolve without chewing or moving it around. Do not eat or drink anything until the film or tablet has completely dissolved. Once it has, take a large sip of water, gently swish it around your teeth and gums, and swallow. This rinse step matters for your dental health (more on that below). Try to use the same placement technique every time you dose, since consistency affects how much medication your body absorbs.
Protecting Your Teeth
In 2022, the FDA issued a warning about dental problems linked to buprenorphine medicines that dissolve in the mouth. The prolonged contact between the medication and your teeth can contribute to decay, cavities, and other oral damage, sometimes in people who previously had no dental issues.
After each dose dissolves, rinse your mouth with water as described above. Wait at least one hour before brushing your teeth. Brushing too soon can damage enamel that has been temporarily softened by the medication’s acidity. Regular dental checkups become especially important once you start Suboxone, and letting your dentist know you take it helps them monitor for early signs of trouble.
Maintenance Dosing
After the initial induction period, your prescriber will adjust your dose over the first few days or weeks until cravings and withdrawal symptoms are consistently controlled. The typical maintenance dose ranges from 4 mg to 24 mg of buprenorphine per day. Doses above 24 mg per day have not been shown to provide additional benefit.
Most people settle into a stable daily dose within the first one to two weeks. Your prescriber may start you at a lower dose on day one and increase gradually. The right dose is the one that keeps withdrawal symptoms and cravings at bay for a full 24 hours without causing excessive drowsiness or other side effects. If you notice cravings returning in the evening or overnight, that’s worth mentioning at your next visit, as it often signals a dose adjustment is needed.
What to Avoid While Taking Suboxone
Combining Suboxone with benzodiazepines (like alprazolam, clonazepam, or diazepam), alcohol, or other sedating substances is dangerous. These combinations can cause severe sedation, slowed or stopped breathing, coma, and death. This risk is highest when you first start Suboxone or when doses change, but it remains present throughout treatment. Sleep medications and certain muscle relaxants carry similar risks. Be upfront with every prescriber about your Suboxone use so they can avoid prescribing something that interacts with it.
Storage and Disposal
Keep Suboxone film or tablets at room temperature, between 68°F and 77°F. Store them in their original foil packaging until you’re ready to use them, and keep them somewhere children and pets cannot access. Buprenorphine is an opioid, and even a single dose can be dangerous or fatal to someone who isn’t opioid-tolerant, particularly a child.
If you have leftover or expired Suboxone, the FDA recommends flushing the films or tablets (removed from their foil pouches) down the toilet if a drug take-back program isn’t available near you. Do not flush the foil packaging. This is one of the few medications where flushing is the recommended backup disposal method, specifically because the risk of accidental exposure is high enough to outweigh environmental concerns.
Getting a Prescription
Access to Suboxone has expanded significantly. As of January 2023, the special federal waiver (known as the X-waiver) that previously limited which doctors could prescribe buprenorphine has been eliminated. Any practitioner with a standard DEA registration can now prescribe Suboxone, and there are no longer caps on how many patients a provider can treat. This means your primary care doctor, not just an addiction specialist, can prescribe it.
Suboxone can also be prescribed through telehealth visits, as long as the prescription follows federal and state laws. This has made treatment accessible for people in rural areas or those who face transportation barriers. Many online addiction treatment programs now offer initial evaluations and ongoing prescribing entirely through video appointments.
