My Dad is 75 years old has been in and out of the hospital because of exasperations brought on by COPD. He is fine when he gets out of the hospital with 40mg of Prednisone then like many others tapers to 30mg, 20mg then 10mg until he isn't taking any. Then the exasperations start he's back in the hospital and the Prednisone cycle begins again. I have notice he has mood swings as he has become very irritable. He also use to work out with light weights ever morning, he no longer has the desire. He also use to go for walks, in the park treadmill etc. he no longer does those activities either. I also notice his eyes look different. I realize this drug is keeping him alive, but he has become a different person.
