mix of meds are causing severe reactions?

Naloxone and Naltrexone both block the hydrocodone in vicodin, but they don't cause intense nausea and throwing up unless you've developed a dependency or addiction to the drug. Some other drugs contain those two like talwin and subutex. Buprenorphine can produce the same effect but with less effectiveness. You may have an allergy to the hydrocodone and that can cause vomiting in some cases.

Fibromyalgia is a for of rheumatism or arthritis, it's actually something they can't put their finger on. Stop all the mixed meds or let one doctor know what your doing. This mixing can lead to something very serious. They did that to me, with my heart and osteoarthritis. It ruptured my spleen and I had to have my spleen and large intestine, colon removed, I was bleeding internally and almost died. Sometimes going to more then one doctor with another doctor know what's going on can be serious.

I don't know about the fibromyalgia, but I have rheumatoid arthritis and the medication I'm on has no severe side effects. I have moderate mood swings, but I can control them. I would recommend going to see one doctor and getting on a medication regimen and then being monitored.
