I am on Covedilol, Clonidine, Verapamil and Quinapril Blood pressure meds. Currently I take the Corvedilol, Clonidine and Verapamil all in the morning. By mid to late morning my blood pressure has fallen very low. I would like to change and take the Verapamil at lunch and bed time, but am currently taking Quinapril at lunch and bed time as well is there any reason for me not to take the Verapapmil at the same time I am taking the Quinapril? ,
