I take diltiazem for blood pressure. The 120 CD. I don't take it every day, because I get really really tired on it. I alter my lisinopril accordingly with it, and balance the two.

I get peripheral swelling in one foot when I take diltiazem every day. Also I find aerobic movement difficult. I use it mostly in winter to improve my circulation when it is really cold. And I drop my lisinopril by 1/2 when I take the diltiazem every day for an extended period.

I find it can cause severe leg cramps if you don't take some calcium now and then. I use Maalox quick dissolve once or twice a week when I take the diltiazem. All of the calicum channel blockers are implicated in congestive heart failure. So if you get alot of dependent edema on it, or winded report that to the doctor. It varies from person to person. Norvasc which is related was horrible for me, both of my legs swelled terribly and I couldn't tolerate it. I only get a little swelling on the diltiazem.
