Why is this medication prescribed?

Cardizem CD is a medication primarily prescribed to treat high blood pressure (hypertension) and certain types of chest pain (angina). It belongs to a class of drugs called calcium channel blockers, which work by relaxing blood vessels and improving blood flow, thereby reducing blood pressure and relieving chest pain.

How should this medicine be used?

Cardizem CD (diltiazem) is typically prescribed for the treatment of high blood pressure (hypertension) and certain types of chest pain (angina). The medication comes in extended-release capsules, which are designed to release the medication slowly over time.

Here’s how Cardizem CD is commonly used:

• Dosage: The dosage of Cardizem CD varies depending on your medical condition, response to treatment, and your doctor’s recommendations. It’s essential to follow your doctor’s instructions carefully regarding dosage.
• Administration: Cardizem CD capsules are taken orally, usually once daily. They can be taken with or without food. Swallow the capsules whole; do not crush, chew, or break them.
• Consistency: Take Cardizem CD at the same time each day to maintain a consistent level of medication in your bloodstream. This helps ensure optimal effectiveness.
