Buprenorphine, sold under the brand name Subutex, is used for opioid addiction once withdrawal symptoms have begun. Subutex comes in tablets or films which are dissolved under the tongue. The goal of this medication is to suppress and reduce cravings for opioids, with high doses making it almost impossible to feel the effects of further opiates.
Subutex must be administered when the client is already in withdrawal. Otherwise, it can put them into a severe instantaneous withdrawal. This is why it is recommended that a client is induced into this in a controlled environment. It is also important to note that Subutex can only be taken for a limited amount of time, as it has the potential to increase opioid dependency when overused.
