Suggest Remedy For Auditory Hallucinations

Dear Dr. Mintz I am a 68 year old widow, last year I start hearing voices in a distance. I went to my dr, and according to her it was old age During the start of February this year it became loud Again I went to another dr. which prescribed SERDEP 50.......I used this for two weeks now, the voices is much better, although it is still there. My question must I stay on SERDEP 50 ?
