https://rxchat.com/Discuss/Opana-30mgs-230788_s2.htm?utm_source=forums_posts&utm_medium=RSS&utm_campaign=RSS I take opana 30mg everyday but it is no longer prescribed, as my insurance lapsed when my husband died. I am on probation &amp; have tested negative for it every month until today. Luckily i had an old vicodin bottle with me &amp; convinced her it shows up as the same. I tested positive for oxy. Why would this happen today &amp; never before? - Filed in Opana en-us Copyright 2026 RxChat.com. All Rights Reserved.
