Whats the Difference Between Subutex and Suboxone

Opioid dependence is a complex medical condition that requires comprehensive treatment approaches. Two medications commonly used in the management of opioid dependence are Subutex and Suboxone. While they serve similar purposes, they have distinct differences that are important to understand.

What is Subutex?

Subutex is a medication primarily composed of buprenorphine, a partial opioid agonist. It is used in the treatment of opioid dependence to help alleviate withdrawal symptoms and cravings. Subutex is often prescribed during the initial phase of treatment, known as the induction phase.

What is Suboxone?

Suboxone is a combination medication containing both buprenorphine and naloxone. In addition to buprenorphine’s role in reducing withdrawal symptoms and cravings, naloxone helps to deter misuse by blocking the effects of opioids if the medication is crushed and injected.

Differences Between Subutex and Suboxone

  • Active Ingredients:

Subutex contains only buprenorphine, while Suboxone contains both buprenorphine and naloxone.

  • Purpose of Use:

Subutex is primarily used during the induction phase of treatment, whereas Suboxone can be used in both induction and maintenance phases.

  • Administration:

Both medications are administered sublingually (under the tongue), but Suboxone’s formulation includes naloxone to deter misuse.

  • Regulation:

Suboxone is subject to stricter prescribing regulations due to the inclusion of naloxone.

  • Cost:

Subutex may be less expensive than Suboxone due to differences in formulation and regulation.

Choosing Between Subutex and Suboxone

When deciding between Subutex and Suboxone, various factors should be considered, including the patient’s medical history, the stage of treatment, and cost considerations. Healthcare providers can offer guidance based on individual needs.


Studies have shown both Subutex and Suboxone to be effective in treating opioid dependence, with comparable outcomes in terms of reducing opioid use and improving patient outcomes.


Both medications have a safety profile, but they can cause side effects such as nausea, constipation, and drowsiness. Additionally, misuse of Suboxone can lead to withdrawal symptoms due to the presence of naloxone.
