I Am Already Taking Metropolal And Lisinopril For High Blood

I am already taking metropolal and lisinopril for high blood pressure. I was taking nephedipine, but my cardiologist stopped it because of sudden blood pressure drops causing weakness and dizziness. While I was in a skilled nursing home temporarily, the nursing home doctor prescribed a 30-day supply of terazosin (1 mg.) and I am wondering if I should even ask my primary care physician for a refill.
