the meds in those patches are up to 40 x stronger than morphine. in the long
termit could be a nasty addiction, in the short term
fentynal is accused of lowering respirations, raising body temp, irritation at the patch site, and in some instances causing moderate to extreme mood swings. if you must take them, take them the way the package says, no more than that. i would ask why the doctor thinks the jump to fentynal is needed, did you try and fail other pain killers?
