I had my GB surgery 14 years ago & b/c of back issues/surgery, was on heavy pain meds for 10 of those years. When I got married 4 years ago, I elected to switch to a Suboxone program with the hope of being able to have children. (Which I never could've done on all the narcotics) And while I am now the proud Mama of a 2 year-old & 6 month-old TWINS, I have suffered through some very extreme negative side effects from Suboxone.
It was only recently that I discovered my problem was w/the NALOXONE (1 of the 2 active ingredients in Suboxone)
Turns out that even though Suboxone is taken sublingually - not usually an absorption issue for GB patients - the NALOXONE is actually swallowed & destroyed in the GI tract, never causing SE's. However as we are well aware, the altered system in post GB patients does not effectively "destroy" the NALOXONE & allows it to reach the brain, where it can do some nasty sh*t to really F w/you!!
Bottom line: Post Gastric Bypass patients should NEVER take SUBOXONE - instead, the generic, 1-ingredient alternative, SUBUTEX (BUPRENORPHINE)
