Precipitated withdrawal occurs when a person is administered an opioid antagonist (such as naloxone) or a partial opioid antagonist (such as buprenorphine) to counter the effects of an opioid agonist (such as OxyCodone, heroin). It is a relatively common experience of those who have had an overdose reversed by Naloxone or who have begun treatment with buprenorphine.
If you are prescribed a course of buprenorphine, it's very important that you are open and straightforward with your provider about when your last use of opioids was and your use history. Without this information your provider will not be able to accurately prescribe you the dose you need to fight your symptoms and prevent you going into precipitated withdrawal.
