Suboxone is not a traditional pill that you swallow. It comes as a thin film or a tablet that dissolves under your tongue or inside your cheek. The brand-name version sold today is a sublingual film, though generic sublingual tablets containing the same ingredients are still available.
How Suboxone Is Actually Taken
Suboxone contains two active ingredients in a 4:1 ratio: buprenorphine, a partial opioid that reduces cravings and withdrawal symptoms, and naloxone, which discourages misuse. Both are designed to absorb through the thin tissue under your tongue or along your inner cheek, not through your digestive system.
The brand-name product is an orange rectangular film, similar in size to a postage stamp. You place it under your tongue or against the inside of your cheek and let it dissolve completely. Films dissolve in roughly 3 minutes on average. You shouldn’t eat or drink anything until the film is fully gone. The film comes in four strengths: 2 mg, 4 mg, 8 mg, and 12 mg of buprenorphine (each paired with a proportional amount of naloxone).
Why You Can’t Just Swallow It
Buprenorphine has very poor oral bioavailability, meaning your body breaks down most of it during digestion before it ever reaches your bloodstream. When held under the tongue, roughly 30 to 50 percent of the drug gets absorbed directly into the blood vessels there. If you swallowed it like a regular pill, that number would drop dramatically due to what pharmacologists call first-pass metabolism, where the liver filters out the drug before it can take effect. This is why the FDA labeling explicitly states: do not cut, chew, or swallow the tablets or film.
Naloxone, the second ingredient, also plays a role here. When absorbed under the tongue, naloxone has very poor bioavailability, so it essentially stays inactive and doesn’t interfere with treatment. But if someone were to dissolve the medication and inject it, the naloxone would activate fully and could trigger withdrawal symptoms. This design is an intentional safeguard against misuse.
The Tablet Version Still Exists as a Generic
Suboxone did originally come as a sublingual tablet: a small, hexagonal, orange tablet placed under the tongue the same way as the film. The brand-name manufacturer discontinued the tablet in March 2013, shifting production entirely to the film format. The FDA confirmed this discontinuation was not due to safety or effectiveness concerns.
Generic versions of the sublingual tablet remain available, typically in two strengths: 2 mg/0.5 mg and 8 mg/2 mg of buprenorphine/naloxone. These tablets take a bit longer to dissolve than the film, usually between 3 and 8 minutes. If a dose requires more than two tablets, you can place them all under your tongue at once or do two at a time, keeping them in place until each set fully dissolves.
Film vs. Tablet: Practical Differences
Both forms deliver the same active ingredients through the same route, so the therapeutic effect is comparable. The main differences come down to daily convenience. Films dissolve faster, averaging about 3 minutes compared to roughly 4 minutes for tablets, though individual times vary. In supervised dosing settings like clinics, the film’s faster dissolve time (sometimes under 30 seconds for monitoring purposes) makes it easier for staff to confirm the dose was taken properly.
Films also come in a wider range of strengths, which can make dose adjustments simpler without needing to split or combine multiple tablets. Some people prefer the film because it’s thinner and less noticeable in the mouth, while others find the tablet easier to handle. Both require the same basic instruction: place it under your tongue, don’t chew or swallow, and wait until it’s completely dissolved before eating or drinking.
Other Buprenorphine Products to Know About
Suboxone is one of several buprenorphine-based products used for opioid use disorder. Subutex was a sublingual tablet containing only buprenorphine without naloxone, though it too has been discontinued as a brand name (generics remain). There are also long-acting options like monthly injections and six-month implants that eliminate the need for daily dosing entirely. All of these contain buprenorphine as the core medication, just delivered differently depending on a person’s treatment needs and preferences.
