Summary

  • Diltiazem is used to treat high blood pressure, which is hypertension, and certain heart conditions like angina, which is chest pain. It can also help manage irregular heartbeats. By improving blood flow, it reduces blood pressure and chest pain.

  • Diltiazem works by blocking calcium channels in the heart and blood vessels, which relaxes the blood vessels and improves blood flow. This action lowers blood pressure and reduces the heart's workload, helping to alleviate chest pain and manage heart conditions.

  • The usual starting dose for adults is 30 mg to 60 mg taken three to four times daily. The maximum recommended dose is 360 mg per day. Diltiazem is usually taken orally, with or without food. Always follow your doctor's specific dosing instructions.

  • Diltiazem should not be used if you have severe low blood pressure, recent heart attack, or certain heart blocks without a pacemaker. It can interact with other medications, so inform your doctor about all drugs you take. Avoid grapefruit juice, as it can interfere with Diltiazem.
