I have a daughter diagnosed DD that was prescribed Prednisone 20 mg. twice a day for seven days for skin allergies. She could only tolerate taking this medication for TWO DAYS without serious side effects. She developed a rash, profuse sweating on both her hands and had to change clothes several times a day for a week due to excessive sweating. She had swelling on her ankles. She developed catatonia that was diagnosed by her personal psychiatrist due to the Prednisone and has been told to NEVER take Prednisone again because she is allergic to this medication.
