Menstrual dysfunction is listed as one of the side effects of Prednisone. There is not a lot of information about Prednisone and Menorrhagia. The general information regarding this subject merely states that Prednisone usage may lead to problems related to menstrual cycles. Women may experience irregularity in their menstrual cycle occurrence, very heavy or unremitting occurrences, or they may experience no menstrual cycle occurrence at all.
Sorry I could not find more information for you, but I hope that this helps a little
Peace and Blessings
Look For The Good and Praise It!
