Re: can use some advise
I would also doubt that the irregularity would be caused by dulera. Because the inhaler sends the meds direct to the lungs as opposed to other parts of the body. I would suspect that either it is unrelated, or it is from the prednisone. My periods have always been very regular, but at times if I had recently taken prednisone, it messed me up for a couple of months. I would skip a month, then have 2 the next month, etc. My gyn did confirm that menstrual irregularity can be a side effect or oral steroids.
