Try not to get discouraged; it can be very hard to subdue a flare initially after diagnosis. It's not unusual to take only Pred; I did that to fight a severe left-sided flare that nearly blocked my colon entirely. For me, the 40 mg daily started working right away. The problem is that your inflammation has not responded to a conservative dose of Pred so your doctor upped it to the maximum permissible oral daily dosage, 60 mg. It could be that you do need IV medication if this higher dose of Pred still does not relieve your symptoms. There are many members here who have experience with IV meds-- hopefully they'll give you helpful feedback soon. / Old Hat (nearly 30 yrs with left-sided UC; currently on 3 Colazal daily for maintenance of remission)
