My Husband Has COPD And Just Finished A Series Of

My husband has COPD and just finished a series of prednizone (sp) last Friday. His Dr. also gave him Spiriva respimat to use...Starting Last Thursday he has experienced excessive dry mouth and frequent urination (by frequent, I mean he is drinking water or eating something fruity almost constantly--and urinating at least every half hour (if not sooner.) Needless to say he is not getting very good rest and sleep....his temp is 96.2 today and he "Just doesn't feel good". Should we be concerned? Is this normal? Should I take him in? He turns 72 yrs old tomorrow.
