Just seeing if anyone takes both of these together and is it ok?..reason i ask is because when i went and seen my cf doctor they started me on advair but was un aware that the transplant doc started me on metoprolol. When i had called my transplant doc she said that if i had asthma that maybe metorpolol wasnt a good idea?..but it was not confirmed i have asthma. Im being prescribed metoprolol because i have a high heart rate even before i started advair but my oxygen is normal..so they want me to take half a 25mg pill twice a day so yes its a low dose i think the lowest as i know people who take alot more higher dose..so if anyone can share there thoughts or personal experiences thatd be great <img src="i/expressions/face-icon-small-smile.gif" border="0"> thanks!
