I have been prescribed Suboxone for about a year and a half. I am prescribed the 8 mg/ 2 mg Buprenorphine and Naloxone Sublingual Films. Anyhow, since I have been on this medication, my pulse/heart rate stays dangerously high. At a complete rest, my heart rate is anywhere between 130-145 bpm. I am also experiencing severe Panic Attacks, now. There is another medication that serves the same purpose, but does not contain Naloxone. The greatest side effect of Naloxone is rapid heart rate. This other medication is called Subutex. I have been to heart specialists, had many test completed and put on various beta blockers, etc Nothing is bringing my heart rate down, and too often I am in "Stroke" or "Heart Attack" range; Still, there is nothing wrong with my heart (for example... heart disease, COPD, blockages, etc.)!. Has anyone else experienced this with this medication Suboxone? Has anyone switched from Suboxone to Subutex because of this side effect? If so, does the Subutex work as well as the Suboxone? The Suboxone has literally saved my life from opiate addiction, meanwhile it is causing other serious health issues. Please, help?
