My Husband Has PTSD, Depression, And Anxiety Disorder. Has Atte.pted

My husband has PTSD, depression, and anxiety disorder. Has atte.pted suicide in 2014 and had suicide thoughts a month ago. He is taking 10 mg abilify. 40 mg celexa, 40 mg lisinopril,5 mg eliquis, and 2 mg of prazosin at night. He just started taking the prazosin again after 2 years for nightmares. Last time he was taken off lisinopril. No he has a 100 mg of trazodone that an ER Doctor gave. Is that safe to take with everything else?
