Suboxone is a brand-name medication that comes as a sublingual (under the tongue) film. It’s available in a generic version called buprenorphine/naloxone. This article describes dosages of Suboxone.

Because it contains buprenorphine, Suboxone is classified as a Schedule 3 controlled substance. A controlled substance is a drug the government regulates due to the risk of dependence or misuse. For more information about these risks related to Suboxone, see this overview article.

Doctors prescribe Suboxone sublingual film to treat opioid dependence. Opioid dependence is treated in two phases: induction and maintenance. During the induction phase, Suboxone sublingual film helps prevent withdrawal symptoms as you reduce your opioid use. (Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.) During the maintenance phase, treatment with Suboxone sublingual film continues at a stable dose for a longer period.

Dosage for induction phase

Suboxone sublingual film is only used for induction if you’re dependent on short-acting opioids, such as heroin, codeine, and morphine. For induction, Suboxone sublingual film should be placed under the tongue. You should not use it inside the cheek because it can increase the risk of withdrawal symptoms. The first dose of Suboxone sublingual film should be given:

  • when moderate opioid withdrawal symptoms start
  • at least 6 hours since your last dose of an opioid

The following table shows the recommended dosages of Suboxone sublingual film for induction treatment. The dosages are in milligrams (mg).

Day of inductionStarting dosageMaximum dosage
Day 1• 2 mg buprenorphine/0.5 mg naloxone
or
• 4 mg buprenorphine/1 mg naloxone
8 mg buprenorphine/2 mg naloxone
Day 2depends on your withdrawal symptoms16 mg buprenorphine/4 mg naloxone

Dosage for maintenance phase

For maintenance, Suboxone sublingual film can be placed under the tongue or inside the cheek. Doctors will adjust your dosage of Suboxone sublingual film to a level that keeps you stable and prevents opioid withdrawal symptoms.

The recommended dosages of Suboxone sublingual film for maintenance treatment in milligrams (mg) are:

  • Typical maintenance dosage: ranges from 4 mg buprenorphine/1 mg naloxone to 24 mg buprenorphine/6 mg naloxone once per day
  • Recommended target dosage: 16 mg buprenorphine/4 mg naloxone once per day
  • Maximum dosage: 24 mg buprenorphine/6 mg naloxone once per day

Dosage adjustments for Suboxone

Your doctor will prescribe a dosage of Suboxone sublingual film based on several factors. These include:

  • the specific condition being treated and how severe it is
  • your age
  • other health conditions you may have

Missed dose of Suboxone

If you realize you forgot to take a dose of Suboxone sublingual film, take the dose as soon as you remember. If it’s almost time for your next dose, skip the missed dose and take the next dose at your regular time. Do not try to catch up by taking two doses at the same time unless a healthcare professional tells you to do so. If you’re not sure about your dosing, talk with your doctor.

How do I know if my dose of Suboxone is too low?

Suboxone sublingual film is used to treat dependence on opioid drugs. It does this by preventing withdrawal symptoms that occur as you reduce or stop opioid use. (Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.)

If you experience opioid withdrawal symptoms while you are being treated with Suboxone sublingual film, your dose may be too low. Symptoms of opioid withdrawal include:

  • restlessness
  • anxiety
  • eyes tearing up
  • runny nose
  • sweating
  • difficulty sleeping
  • yawning
  • diarrhea
  • stomach cramps
  • rapid heart rate
  • high blood pressure

If you have more questions about this, talk with your doctor.

Can Suboxone be used for pain? If so, what is the dosage?

Maybe. But Suboxone sublingual film is only approved to treat opioid drug dependence. It’s not approved to treat pain.

In some cases, doctors may prescribe Suboxone off-label for pain. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved for.

If you have questions about taking Suboxone for pain, talk with your doctor.

Is Suboxone taken long term?

It can be. Doctors may prescribe Suboxone sublingual film as a short-term or long-term treatment. If you and your doctor decide that it’s safe, beneficial, and contributes to your intended treatment goals, you may take it long term.

If you have questions about how long you should take Suboxone sublingual film, talk with your doctor.

Is there a risk of dependence or withdrawal with Suboxone?

Yes. Taking Suboxone sublingual film can cause dependence. (With dependence, your body needs the drug to function as usual.) And if Suboxone sublingual film is suddenly stopped or the dosage is decreased too quickly, it can cause withdrawal symptoms. (Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.)

Examples of Suboxone sublingual film withdrawal symptoms include:

  • diarrhea
  • headache
  • difficulty sleeping
  • irritability
  • sweating

Because of these risks, your doctor will likely lower your dosage of Suboxone sublingual film slowly over time until it’s safe for you to stop the drug completely.

If you have more questions about the risk of dependence or withdrawal with Suboxone sublingual film, talk with your doctor.

How Suboxone is taken

Depending on your phase of treatment, you’ll place Suboxone sublingual film under the tongue or inside the cheek once per day. Keep the film in place until it dissolves completely. You should not eat or drink anything until the entire film is dissolved.

You should place the Suboxone sublingual film whole. Do not cut or chew the film.

If you are placing Suboxone sublingual film under the tongue, place it close to the base of the tongue on the left or the right side. If you are using two films to make up your dose, place one film on each side of the tongue and try not to overlap the films. If you are using three films to make up your dose, let the first two films dissolve first. Then, place the third film on either side under the tongue.

If you are placing Suboxone sublingual film inside the cheek, place the film inside the right or left cheek. If you are using two films to make up your dose, place one film inside each cheek. If you are using three films to make up your dose, let the first two films dissolve first. Then, place the third film inside either cheek.

After Suboxone sublingual film has completely dissolved, take a sip of water, swish the water around your mouth, and swallow. Wait at least 1 hour before you brush your teeth.

Your doctor may advise that you take this medication around the same time each day. This helps keep a consistent amount of the drug in your body. And that can help the drug work better.

Also, be sure to talk with your doctor or pharmacist if you are having difficulty taking your medication. They can recommend ways to take it.
