Both Subutex and Suboxone contain buprenorphine, a medication that can help people beat opioid addiction by minimizing withdrawal symptoms and easing cravings. Both Subutex and Suboxone are taken once a day and can be either given by a healthcare professional or taken home for at-home use.

But there are differences between them, such as:

  • Subutex contains only buprenorphine but Suboxone contains naloxone in addition to buprenorphine (naloxone helps protect people from an inadvertent opioid overdose)
  • Subutex is a sublingual tablet and Suboxone is a film that you put under your tongue
  • Subutex was approved in 1981 and Suboxone has been available since 2002.
  • Both Subutex and Suboxone can be initiated early by a doctor as part of an opioid treatment program. The brand name Subutex has been discontinued in the U.S. but it is available as generic buprenorphine sublingual tablets.
