Usual recommended dosage of buprenorphine in adults

Typically, doctors prescribe buprenorphine sublingual tablet for the induction (starting) phase of OUD treatment. In some cases, a doctor may prescribe it for the maintenance (long-term) phase of your OUD treatment. Maintenance treatment may include buprenorphine alone or buprenorphine with another medication. But your doctor will prescribe the smallest dosage that gives the desired outcome.

Usually, doctors start by prescribing a dosage within a recommended range. Your starting dosage will depend on the severity of your opioid withdrawal symptoms.* It will also depend on the dosage of opioids you’ve been taking.

The recommended dosages are:

  • Starting dosage: 2–8 milligrams (mg) as a single dose
  • Maintenance dosage:4–24 mg per day

* Withdrawal means side effects that can occur when you stop taking a drug on which your body has become dependent. Dependence means your body needs the drug to function as usual.
† This is the recommended dosage of buprenorphine taken alone for maintenance treatment. If your doctor prescribes buprenorphine with another medication, the dosage may differ.

Is there a risk of misuse, dependence, or withdrawal with buprenorphine?

Yes, that risk exists. Buprenorphine is a controlled substance. This means it has the following risks:

  • misuse: taking a drug in a way other than how a doctor prescribes it
  • dependence: a state when your body needs the drug to function as usual
  • withdrawal: side effects that can occur when you stop taking a drug on which your body has become dependent

If you take buprenorphine sublingual tablet, it’s important to follow your doctor’s instructions. This means you should take your dosage exactly as your doctor prescribes.

If you have questions or concerns about any of these risks, talk with your doctor.

How buprenorphine is taken

If you’re taking buprenorphine sublingual tablet for the induction (starting) phase of opioid use disorder treatment, you’ll take it as a single dose.

Take the tablet without food or drink. You’ll take the tablet by placing it under your tongue and letting it dissolve. Once it dissolves, sip water, swish it gently around your teeth and gums, and then swallow it. Following your dose, do not brush your teeth for at least 1 hour.

If your dosage requires more than one tablet, take them both at the same time. Do not chew, break, cut, or swallow the tablets whole.

You’ll take your first dose once you start having withdrawal symptoms after stopping opioids. Usually, your first dose should be at least 4 hours after you last took a short-acting opioid drug, such as heroin. Also, your first dose should be taken 24 hours or more after taking a long-acting opioid, such as methadone.

You’ll likely receive your induction doses of buprenorphine sublingual tablet in your doctor’s office. Based on your response to the first dose, your doctor may increase your dosage the following day.

Afterward, buprenorphine is usually taken along with naloxone for maintenance (long-term) treatment. But sometimes buprenorphine sublingual tablet is taken alone.

For maintenance treatment, you and your doctor will discuss where to take your doses. You might agree to take your doses at your doctor’s office. Or you might feel ready to take them at home by yourself.

Your doctor may advise that you take buprenorphine sublingual tablet 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 more effectively.

Also, be sure to talk with your doctor or pharmacist if you’re having difficulty taking your medication. They can offer recommendations about taking it.
