My husband started on Lisinopril - 6/11/08. He also takes Coreg generic. He also takes Crestor. However, before taking Lisinopril, he had a persistent cough dating back to March. He was placed in prednisone for five days - 6/14/08. He has had chest pain, numbing of different sections of his legs, arm numbness. But, today, he threatened to attack me with a remote control and wished a tv to fall on my head. This is psychotic behavior. Has anyone else experienced violent eposides and incoherant moments?
