A buccal tablet is placed between your upper gum and the inner lining of your cheek, where it dissolves slowly and absorbs directly into your bloodstream. Unlike a regular pill you swallow, a buccal tablet is designed to stay in place against your cheek tissue until it fully dissolves. The process is simple once you know the correct placement and a few key rules.
Step-by-Step Placement
Start with dry hands and a reasonably dry mouth. If you’ve just been drinking water, wait a minute or two before placing the tablet. Then follow these steps:
- Find the buccal pouch. Gently pull back one side of your mouth so you can see the space between your upper gum and the inside of your cheek. This pocket is where the tablet goes.
- Place the tablet. Press it gently against the gum line on either side of your mouth (unless your prescription specifies a side). Some buccal tablets have a flat side designed to sit against the gum, so check your packaging for any specific orientation instructions.
- Hold still briefly. Close your mouth and let the tablet settle. Avoid poking it with your tongue. Within a few seconds, moisture from your cheek lining will help the tablet begin to adhere.
- Leave it alone. Stay still and let the tablet dissolve completely on its own. Depending on the medication, this can take anywhere from a few minutes to several hours. Do not chew, crush, or swallow it.
You can alternate which side of your mouth you use with each dose to reduce irritation in one spot.
Why Buccal Tablets Work Differently
When you swallow a regular pill, it travels to your stomach and intestines, gets broken down, and then passes through your liver before reaching your bloodstream. Your liver filters out a significant portion of the drug during this trip, a process called first-pass metabolism. That means less of the active medication actually makes it into circulation.
Buccal tablets skip that entire route. The inner lining of your cheek is thin, rich with blood vessels, and has relatively low enzyme activity compared to your gut. The medication passes directly through the cheek tissue into a vein that carries it straight into general circulation. This is why some drugs are specifically formulated as buccal tablets: the cheek delivers more of the drug into your system than swallowing would, and often does it faster.
The cheek lining absorbs drugs through two main pathways. Fat-soluble drug molecules pass directly through cells in the tissue, while water-soluble molecules slip between cells. Your saliva’s natural pH influences how well this absorption works, which is one reason you’re told not to eat or drink during the process.
What to Avoid While the Tablet Dissolves
While the tablet is in place, don’t eat, drink, or chew gum. Food and liquid can dislodge the tablet or dilute the medication before it has time to absorb. Even swishing the tablet around with your tongue can interfere with how well it sticks to the tissue and how evenly the drug absorbs.
Smoking is also best avoided. Heat and chemicals from smoke can irritate the cheek lining and alter blood flow to the area, potentially changing how much medication gets absorbed. If your medication instructions specify a buffer time after the tablet dissolves (commonly 30 to 60 minutes), wait that long before eating or drinking anything.
What Happens If You Accidentally Swallow It
If you swallow the tablet by mistake, what you do next depends on timing. As a general guideline used for some buccal medications: if you swallow it within the first six hours of placing it, drink a glass of water and apply a new tablet. If it falls off or gets swallowed six or more hours after you placed it, a significant portion of the drug has likely already absorbed through your cheek, so you typically do not need to replace it until your next scheduled dose.
Swallowing a buccal tablet won’t usually cause harm, but it will reduce how well the medication works. The whole point of buccal delivery is to avoid the digestive system, so a swallowed tablet may be partially broken down by your stomach and liver before it reaches your bloodstream. Don’t double up on doses without checking your specific medication’s instructions.
Tips for Keeping the Tablet in Place
Some people find that buccal tablets shift around or feel awkward at first. A few practical adjustments help. Try not to talk much while the tablet is dissolving, since jaw movement can loosen it. If you produce a lot of saliva, resist the urge to swish it around. Instead, let saliva collect naturally and swallow gently without dislodging the tablet.
If you’re giving a buccal tablet to a child or someone who can’t hold still, positioning them on their side with the medicated cheek facing down helps gravity keep the tablet in place. This is the same technique used in pediatric settings at children’s hospitals.
For tablets that take a long time to dissolve, you can go about light activities like reading or watching TV. Just avoid vigorous exercise or situations where you’d need to drink water frequently. If you notice the tablet crumbling rather than dissolving smoothly, or if it repeatedly falls off, mention this to your pharmacist. Some buccal formulations are designed with adhesive properties, and a different brand or formulation may work better for you.
Buccal vs. Sublingual: They’re Not the Same
People often confuse buccal tablets with sublingual tablets, but the placement is different and it matters. Sublingual tablets go under your tongue, where the tissue is thinner and absorption tends to be faster. Buccal tablets go between your cheek and gum, where absorption is slower and more sustained. Some medications are designed to release over hours through the cheek lining, which wouldn’t work under the tongue.
Using the wrong placement can change how quickly or completely your body absorbs the drug. Always place the tablet exactly where your prescription label or pharmacist directs: “buccal” means cheek, “sublingual” means under the tongue.
