A: Accupril (quinapril) is a medication that can be used for blood pressure. It is already to split Accupril tablets and the tablets come in several different doses.

If your blood pressure is too low on your current medications your provider may have you decrease the strength of one of your medications or he/she may take you off of one medication completely. It would be helpful to check your blood pressure at various times of the day and write the readings down to show to your provider so they will have several numbers to go off of rather than just the reading you get in the office.
