I had a severe bout of allergy this fall and my doctor prescribed prednisone. Before I started taking it I was aware there is a chance for it to cause side effects and in the start, I didn't make the connection because I had a UTI roughly at the same time I started prednisone. However, I had a course of Cipro and all UTI symptoms were gone, except one – I still feel I need to urinate every two hours. This happens no matter if it’s day or night and it’s becoming unbearable. It’s not caused by another urinary infection, but I was wandering does prednisone cause frequent urination? I have my appointment scheduled in a month to get my doctor to either take me off the prednisone or just do anything to stop this, but I’d appreciate a lot if anyone who was on prednisone could help me with an answer.
