Hi Judy, My Riley is on prednisone also which has really helped his symptoms. He also takes 5 mg of pepcid as prescribed by the neuro. Riley did have one accident at night but that was my fault. He pees a much longer time when he goes and of course is drinking alot more. Riley has had no stomach upset at all. Only been 10 days but so far so good. He is also on tramadol on an as needed basis now.
