I just started taking Burporion 200mg once a day two weeks ago, just yesterday I started experiencing, some of the side effects listed, such as dry mouth, irregular heart beat, shortness of breath, itching, chest pain, and fainting! but can side effects start this late? And is it possible they could subside, after a few days? I am also taking-Paroxetine HCL 20 mg once a day, Clonazepam 0.5 mg 3X day. as well as Propranolol 10 mg 3x a day, and lisinopril 10mg 1 a day. please help!!! confused and tired of all the med changes.
