Side effects of predisone symptoms and conditions

Behavioral changes started when my son was 3 years old and on Singulair, 4mg chewables. He became more angry, irritable, and even stated a few times that he wished he were dead. He has had trouble concentrating and has frequent nightmares.

Regarding the other post, headaches are a listed side effect. I took prednisone for two days - 40mg each. I am on day 3 without taking it due to side effects. At first anxiety symptoms and shaking hands and shortness of breath, then excessive sweating, abdominal pain, excessive urination, and hip and shoulder pain. Never mind the mood and personality changes, which occurred within hours of taking the 1st dose. Now, I still have really bad shoulder pain and sweating. Anyone who has gone through this, how long does it take, and what can help my body get over this faster??? Doctors should better inform patients of side effects - and my doctor is having me tested for parvovirus today--even though the symptoms I have are not consistent with it, and are all listed side effects of predisone----by the way, I had to find the side effects myself. I was sick (broncitis) and did not have the energy when I started the medication. Now I am angry that I was so poorly informed.
