What Diltiazem ER is
A long-acting calcium channel blocker. It relaxes blood vessels and slows the heart rate, which lowers blood pressure and eases the heart’s work.
What it’s for
High blood pressure and angina. It is also used to slow a fast heart rate in atrial fibrillation (an irregular heartbeat).
How it’s taken
By mouth, once a day. Swallow it whole; don’t crush or chew it.
Good to know
It interacts with many medicines, including some statins and blood thinners, so the pharmacist should see the full medicine list. It can slow the pulse too much, especially with a beta-blocker. Fainting, a very slow pulse, or new shortness of breath needs prompt care.
