His doctor switched him to Opana ER 10MG and gave him Opana IR
5MG incase of break through pain. He took his first
Opana ER on Jan12 about 6pm and has been regularly taking the Opana IR, my concern is that it has been 48 hours since he switched and he has been nauseated, and has the chills but no temp, and achy, could this be withdrawl symptoms from the Norco even though the doc started him on something else?
