The doctor indicated I needed to use the higher dosage of the medicine but a few hours after I take it, I feel like something is in my throat and can't breath. I went to an ENT and he was unable to find anything. Tried sleeping with a humidifier and still no help. The medicine they are trying to change me to (Sprycel) cost $12,100.00 per month and is not covered by my insurance. Any advise or if you have experience any of these symptoms taking this drug would be greatly appreciated.
