I Have Itp Since 1994 But Had An Hemorage Because

I have itp since 1994 but had an hemorage because platelets went down to 28000 bleeding nose and from mouth. Dr put me on prednisone starting st 80 and now down to 10. But today count is now down to 42000 and since on a reduction of my prednisone is steadily going down. I also take citalopram 20 mg and clonazepam .5mg 3 times daily for panic disorder could my pills for panic disorder be causing my low platelets count. Female 62 years old
