Diltiazem is a calcium channel blocker used for high blood pressure and angina. It relaxes blood vessels and eases the heart’s workload.

What Diltiazem Is Used For

  • High blood pressure
  • Angina (chest pain)
  • Some irregular heartbeats

Common Side Effects

  • Ankle swelling
  • Headache
  • Slow heartbeat

Precautions

Take slow-release forms whole, without crushing. Do not stop diltiazem on your own, as symptoms can return. Tell your doctor about a very slow heartbeat, dizziness or swelling. Grapefruit juice can raise the level in the body, so avoid it.
