About Suboxone®

The FDA approved Suboxone® in October of 2002 for use in the treatment of opioid addiction. Suboxone® is a registered trademark of and manufactured by Reckitt Benckiser Pharmaceuticals. Suboxone® is composed of the two active ingredients: buprenorphine and naloxone.

Naloxone is used to block the effect of opioids. Buprenorphine is a partial opioid agonist that stimulates opioid receptors but does not produce the same effects as an opioid. In other words it does not produce a euphoric "high" effect. The combination of these two actives has been shown to be efficacious in managing the treatment of opioid addiction. Suboxone® is most often taken sublingually (dissolved under the tongue). Taken properly it can reduce opioid use, help patients to be successfully managed in an addiction rehabilitation program, and depress the symptoms of opioid withdrawal. Suboxone® is the most commonly prescribed medication that is administered to patients during the maintenance phase of treatment. Unlike methadone, Suboxone® has a lower potential for overdose and abuse. This enables Certified Doctors, in certain circumstances, to prescribe take home supplies of Suboxone®.
