How to Take Suboxone: Sublingual and Buccal Steps

Suboxone is a sublingual film or tablet that dissolves under your tongue or inside your cheek. Taking it correctly matters because the medication absorbs through the moist tissue in your mouth, not through your stomach. Swallowing it like a regular pill means most of the active ingredient never reaches your bloodstream. Here’s what you need to know to take it properly and get the full benefit of each dose.

Before Your First Dose

You cannot simply start taking Suboxone whenever you decide to stop using opioids. If you take it too soon after your last opioid dose, the medication can trigger sudden, intense withdrawal symptoms. This happens because one of its ingredients rapidly displaces other opioids from receptors in your brain, leaving you in worse shape than if you’d taken nothing at all.

The general rule is to wait until you’re already in mild to moderate withdrawal before taking your first dose. For short-acting opioids like heroin or oxycodone, that typically means at least 12 hours since your last use. For long-acting opioids, expect to wait 24 hours or longer. If you were taking methadone, the wait is often 48 to 72 hours. Your prescriber will assess your withdrawal symptoms using a standardized scale, and most protocols require a minimum score of 8 out of 47 on that scale before starting you on the medication. Signs that you’re ready include muscle aches, runny nose, nausea, restlessness, and goosebumps.

The first day’s dose is typically small, starting at 2 to 4 mg and increasing in small increments every couple of hours up to 8 mg, depending on how your symptoms respond. By the second day, the dose can go up to 16 mg. This careful ramp-up, called induction, is usually supervised by your prescriber.

Step-by-Step Sublingual Placement

Most people take Suboxone as a sublingual film placed under the tongue. The FDA’s instructions are specific, and each step affects how well the medication absorbs.

  • Moisten your mouth first. Drink some water before placing the film. A dry mouth slows down dissolution and reduces absorption.
  • Hold the film by its edges. Grip it between two fingers on the outside edges to avoid getting the medication on your hands.
  • Place it under your tongue. Position the film near the base of your tongue, to the left or right of center.
  • If taking two films, use both sides. Place the second film under your tongue on the opposite side from the first. Keep them from overlapping as much as possible.
  • Leave it completely alone. Do not chew, swallow, or move the film once it’s placed. Let it dissolve entirely on its own.
  • Don’t talk. Speaking while the film dissolves can interfere with absorption. Plan to stay quiet for several minutes.

If your prescribed dose requires a third film, wait until the first two have fully dissolved before placing it on either side.

For sublingual tablets, the process is essentially the same. Place the tablet under your tongue and let it dissolve without chewing or swallowing. Moistening your mouth beforehand helps here too.

Buccal Placement (Inside the Cheek)

Some formulations are designed to be placed against the inside of your cheek instead of under your tongue. If your prescription calls for buccal placement, wet the inside of your cheek with your tongue or rinse with water first. Place the yellow side of the film flat against the cheek, then press it with clean, dry fingers and hold for about 5 seconds. Leave the film in place until it dissolves completely. Don’t touch or reposition it. Avoid placing the film over any mouth sores or irritated areas.

Eating, Drinking, and Smoking Around Doses

Avoid eating, drinking, or smoking for at least 30 minutes before taking your dose. Anything in your mouth can create a barrier between the film and the tissue it needs to absorb through, or it can dilute the medication and cause you to swallow it rather than absorb it. Once the film has fully dissolved, most people wait at least 10 to 15 minutes before eating or drinking anything. There’s no strict FDA-mandated window for after the dose, but giving the medication extra time to absorb fully is a reasonable precaution.

Protecting Your Teeth

In 2022, the FDA issued a warning that buprenorphine medicines dissolved in the mouth have been linked to serious dental problems, including tooth decay, cavities, oral infections, and tooth loss. These problems have occurred even in people with no prior history of dental issues. The acidic environment created by the dissolving film appears to be a contributing factor.

After the film has completely dissolved, take a large sip of water, gently swish it around your teeth and gums, and swallow. Do not brush your teeth for at least one hour afterward. Brushing too soon can damage enamel that has been temporarily softened by the medication’s acidity. Schedule a dental visit soon after starting Suboxone and let your dentist know you’re taking it. Regular checkups while on the medication are important so your dentist can monitor for early signs of decay and create a prevention plan.

Maintenance Dosing

Once you’ve completed the induction phase, your prescriber will find a maintenance dose that controls cravings and withdrawal without excessive side effects. The FDA-approved maintenance range is 4 mg to 24 mg per day, with 16 mg being the recommended target for most people. This is taken as a single daily dose. Your prescriber may adjust the dose over time based on how you’re responding.

Consistency matters. Take your dose at roughly the same time each day. If you miss a dose, take it as soon as you remember, but don’t double up to compensate. If you’ve missed several days in a row, contact your prescriber before resuming. After four or more missed days, especially if you’ve used other opioids in the meantime, restarting at your full maintenance dose could cause problems, and your prescriber may need to reassess.

Common Side Effects

The most frequently reported side effects are headache, constipation, drowsiness, dizziness, and nausea. These tend to be more pronounced at higher doses. Most people develop tolerance to the drowsiness, dizziness, and sedation within a few weeks of steady use. Constipation, however, tends to persist even after months of therapy. Over-the-counter remedies like stool softeners or increased fiber intake can help.

Numbness in the area where the film dissolved is another common side effect specific to the sublingual film form. This is temporary and typically resolves on its own within minutes.

If you take Suboxone too early, before you’re in adequate withdrawal, you may experience precipitated withdrawal: sudden onset of pain, nausea, vomiting, abdominal cramps, rapid heartbeat, and sweating. This is intensely uncomfortable but generally resolves within hours. It’s the main reason the timing of your first dose is so critical.

What to Avoid While Taking Suboxone

Combining Suboxone with alcohol, sedatives, or anti-anxiety medications like benzodiazepines is dangerous. All of these substances slow your breathing, and adding Suboxone to the mix increases the risk of life-threatening respiratory depression. This combination carries an FDA black box warning, the most serious safety alert the agency issues. Be honest with your prescriber about everything you’re taking, including alcohol and any medications prescribed by other doctors.

Storing and Disposing of Suboxone

Store Suboxone at room temperature, away from moisture and direct light. Keep it in its sealed packaging until you’re ready to use it, and be careful not to cut or damage the film when opening the packet.

Because Suboxone contains an opioid, proper disposal of unused medication is important, especially in households with children or anyone at risk of misuse. Drug take-back programs at pharmacies or community collection events are the safest option. If those aren’t available, mix unused films with something unpleasant like used coffee grounds or cat litter, seal the mixture in a plastic bag, and throw it away. Scratch any personal information off the packaging before discarding it.
