I am almost finished taking a 3 week course of Prednisone- thank goodness! I am in my early 30's. I have had quite a few side effects that I didn't even originally know were from this drug - but now am convinced. I have had a dry mouth and a bad taste in my mouth (for about a week), had an increase in urine output, increased urination, night sweating (at back of head and base of neck especially), inability to sleep through the night, frequent urination at night (previously I never woke up at night to use the bathroom), off and on blurred vision (only in one eye), & muscle weakness of the bladder (mild incontinence) only at night. The things that bother me the most and cause me concern are the urinary issues (waking up at night to use the bathroom is disturbing my already hard to get sleep).
