From the Guidelines

The recommended Suboxone induction for opioid withdrawal typically begins with 2-4mg of Suboxone sublingually on day 1, with subsequent doses administered as needed to manage withdrawal symptoms, as supported by the most recent evidence from 2020 1. The induction phase for Suboxone 2 mg sublingual tablets is crucial in managing opioid withdrawal symptoms. According to the latest guidelines, patients should be in mild withdrawal before initiating Suboxone therapy.

  • The initial dose of 2-4mg can be repeated at 2-hour intervals if well tolerated, until resolution of withdrawal symptoms, with a typical total dose of 4-8mg on the first day 1.
  • On day 2, the total dose from the previous day can be administered as a single dose, with adjustments made as needed to manage ongoing withdrawal symptoms, up to a maximum dose of 16mg 1.
  • It is essential to assess the patient's withdrawal symptoms regularly, using a validated opioid withdrawal scale, to determine the optimal dosing regimen 1.
  • The naloxone component in Suboxone has a minimal effect when taken as prescribed but helps prevent misuse by injection, making it a safe and effective treatment option for opioid withdrawal 1. Key considerations in Suboxone induction include:
  • Ensuring the patient is in mild to moderate withdrawal before initiating therapy
  • Starting with a low dose and titrating as needed to manage withdrawal symptoms
  • Monitoring the patient closely for signs of overdose or underdose
  • Adjusting the dosing regimen as needed to achieve optimal symptom management, with the goal of stabilizing the patient on a daily dose of 12-16mg by day 3 1.

From the FDA Drug Label

2.3 Induction Prior to induction, consideration should be given to the type of opioid dependence (i.e., long- or short-acting opioid products), the time since last opioid use, and the degree or level of opioid dependence Patients Dependent on Heroin or Other Short-acting Opioid Products At treatment initiation, the first dose of Buprenorphine Sublingual Tablets should be administered only when objective and clear signs of moderate opioid withdrawal appear, and not less than 4 hours after the patient last used an opioid It is recommended that an adequate treatment dose, titrated to clinical effectiveness, should be achieved as rapidly as possible. The dosing on the initial day of treatment may be given in 2 mg to 4 mg increments if preferred.

The recommended dosing regimen for Suboxone (buprenorphine/naloxone) during the induction phase of treatment for opioid withdrawal is to administer the first dose when objective and clear signs of moderate opioid withdrawal appear. For patients dependent on short-acting opioid products, this should be not less than 4 hours after the patient last used an opioid, while for those dependent on long-acting opioid products, it should be generally not less than 24 hours after the last use. The dose may be given in 2 mg to 4 mg increments if preferred, with the goal of achieving an adequate treatment dose as rapidly as possible 2. Key points include:

  • Initiating treatment when signs of moderate opioid withdrawal are present
  • Considering the type of opioid dependence and time since last use
  • Starting with a dose that can be titrated to clinical effectiveness
  • Possibly using increments of 2 mg to 4 mg on the initial day of treatment.

From the Research

Induction Phase for Suboxone

  • The recommended dosing regimen for Suboxone (buprenorphine/naloxone) during the induction phase of treatment for opioid withdrawal is not explicitly stated in the provided studies, but the studies suggest that buprenorphine is effective in managing opioid withdrawal 3, 4, 5, 6, 7.
  • Buprenorphine has been compared to clonidine, methadone, and other medications in various studies, and the results suggest that buprenorphine is more effective in ameliorating withdrawal symptoms and improving treatment outcomes 3, 6, 7.
  • The dosage of buprenorphine used in the studies varied, but a common dosage range was 0.6-1.2 mg per day, sublingually 4, and 2-8 mg per day, sublingually 5.
  • The studies also suggest that buprenorphine may offer some advantages over methadone, including quicker resolution of withdrawal symptoms and possibly slightly higher rates of completion of withdrawal 6, 7.

Comparison of Buprenorphine to Other Medications

  • Buprenorphine was found to be more effective than clonidine in alleviating withdrawal symptoms and improving treatment outcomes 3, 4, 6, 7.
  • Buprenorphine was also found to be comparable to methadone in terms of managing opioid withdrawal, but may offer some advantages in terms of quicker resolution of withdrawal symptoms and possibly slightly higher rates of completion of withdrawal 3, 6, 7.

Dosage and Administration

  • The dosage of buprenorphine used in the studies varied, but a common dosage range was 0.6-1.2 mg per day, sublingually 4, and 2-8 mg per day, sublingually 5.
  • Buprenorphine was administered sublingually in most of the studies, and the dosage was typically titrated to achieve optimal withdrawal management 3, 4, 5, 6, 7.
