Should I Spit or Swallow Suboxone?

Table of Contents

Suboxone comes in two dissolving formulations: tablets and films. Both are dissolved under the tongue or cheek (“sublingually”). This usually takes anywhere from 1-5 minutes. Afterward, people may notice a small amount of residue under the tongue which can have an unpleasant flavor or consistency. First time Suboxone users sometimes worry about spitting or swallowing this residue.

How Should I Take Suboxone?

Suboxone is the brand name combination of buprenorphine (a partial opioid agonist) and naloxone (an opioid antagonist that minimizes the risk of overdose).[2] 

Buprenorphine controls drug cravings and can help you avoid withdrawal symptoms that could trigger a relapse. This medication is powerful, but can be a little tricky to get the hang of how to take it: Unlike most pills which absorb well through the stomach lining, Only about 10% of an oral dose of Suboxone gets absorbed through the stomach, but up to 55% is absorbed through oral membranes.[3] For this reason, it come in a tablet/strip for to be dissolved in the mouth so that it becomes more “bioavailable” (more of it is actually absorb and can act in the body).

Spitting vs. Swallowing Residue: Which Is Safest?

People taking Suboxone should let their doses melt completely before eating drinking water, or otherwise opening their mouths.[1] If you take your Suboxone dose properly, you shouldn’t have much residue left over. However, the naloxone component of Suboxone is not dissolved in the mouth and so some people notice a little bit of residue even once the strip is fully dissolved. This residue can have a bitter taste. 

If you do have residue, you can either spit out the residue or swallow it with a sip of water. The choice is up to you. Both are safe. Some people don’t like the taste of the residue or they feel it bothers their stomach in which case they prefer to spit it out. Others don’t mind swallowing it. Either method is equally safe. 

What Is the Spit Trick?

In the so-called "spit trick," people using Suboxone spit out residue, rinse, and spit again. If your mouth feels sticky, chalky, or dry after using your medication, this could be a good option for you. 

What About Swallowing?

People following the FDA's recommendation swish water around in their mouths and swallow the liquid after their doses have completely dissolved.[4] This method won't get you high or make you sick. And it could help with any chalky taste too.

Does Suboxone Impact Your Oral Health?

Buprenorphine products can be hard on your oral health, low saliva levels/dry mouth in the short term and potentially tooth decay in the long term (usually over the course of years). The U.S. Food and Drug Administration recommends the following to help protect your oral health long term: [4]

  • Wait until the product is completely dissolved and then rinse the mouth with water or swipe some water after taking your dose
  • Brush your teeth about an hour after taking your dose. 
  • Make sure you are brushing and flossing regularly 
  • Make sure you are receiving regular care with a dentist 

What to Do While Taking Suboxone

If you have been prescribed Suboxone as MAT, it is important to take it as directed.

Your physician will provide you with specific advice, but in general, follow these steps per the product you're provided:[1]

  • Tablets: Place them under your tongue until they melt completely.
  • Buccal/sublingual films. Wet the inside of your cheek or rinse. Then, apply the film with dry fingers to the inside of your cheek.

When your products are in place, hold your mouth firmly closed and wait for the medication to dissolve. Try not to move the dose around in your mouth but keep it firmly under the cheek/tongue. 

What Not to Do With Your Dose 

You should avoid the following:

  • Tampering with your dose: Do not tear, cut, chew, swallow, touch, move, or otherwise tamper with the film.
  • Misusing your medication: If you feel tempted to misuse your dose and take it in a way other than prescribed, you are at risk of relapse and should speak to your physician, counselor, or rehab program.
  • Taking other substances without talking to your team: Opioids, alcohol, and benzodiazepines could cause oversedation. Discuss their use with your physician before you take these medications with your Suboxone. 
  • Adding too much to your mouth before and after your dose: A rinse with water is recommended. But do not eat, drink, or smoke cigarettes for 15 minutes before and 15 minutes after taking Suboxone.

What Happens When I Swallow Suboxone?

Suboxone doesn’t absorb well through the stomach. It may cause you to feel some nausea or stomach upset if the dose is accidentally swallowed. You will likely not get adequate relief from the medication if the dose is swallowed.

While oral bioavailability is low, it's not zero. If children or pets who have never used buprenorphine swallow your Suboxone, they could get very sick. [5] If there has been an accidental ingestion of your Suboxone, go to the emergency room immediately. 

Keep your medications in a safe, secure location locked away from others inside your home.
