WARNING!

You must be clean before you take naltrexone, otherwise, you will get VERY sick. The withdrawal is WORSE than any you have ever experienced. It is recommended that you be clean for 7-10 days to prevent this from happening unless you have recently taken naltrexone.

An injection of naloxone, a short acting type of naltrexone, may be administered to patients prior to receiving a pellet. If you are clean 7-10 days or taking naltrexone by pellet or pill there will be no effect from this injection. If NOT, in about 10 minutes you will start getting sick. It will wear off in about an hour but we will not put in a pellet.
