What Diltiazem Is and How It Works

This medicine is a non-dihydropyridine calcium channel blocker. It relaxes coronary and peripheral blood vessels and slows conduction through the heart’s AV node. The result can be lower blood pressure, less angina, and controlled heart rate in certain supraventricular rhythms. Many people start with Diltiazem 30mg tablets when immediate-release dosing is prescribed. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

By reducing the heart’s workload and oxygen demand, the treatment may ease exertional chest discomfort. It can also support rate control in atrial arrhythmias when used as directed by a clinician.

Who It’s For

This therapy is used for adults with diagnosed high blood pressure and chronic stable or vasospastic angina. Clinicians also use it for rate control in certain supraventricular tachycardias and atrial fibrillation. Some patients who previously used Cardizem 60 mg may be transitioned to comparable generic regimens under medical supervision. See our condition guides on Hypertension, Angina, and Atrial Fibrillation for context.

People with severe low blood pressure, sick sinus syndrome or AV block without a pacemaker, acute decompensated heart failure, or known hypersensitivity should avoid this medicine. Always review your cardiac history and current drugs with your prescriber.

Dosage and Usage

Immediate-release schedules are typically multiple times daily, while extended-release products are usually once daily. Follow the exact instructions on your prescription label. When immediate-release is used, a clinician may begin with lower doses and adjust gradually. Some patients stabilize on Diltiazem 120 mg, though the correct dose is individualized. Do not crush or chew extended-release capsules or tablets.

Take it at the same time each day. Swallow with water. If stomach upset occurs, a light meal may help. Avoid grapefruit or grapefruit juice unless your clinician says otherwise due to potential interaction.

Strengths and Forms

Available forms include immediate-release tablets and extended-release capsules or tablets. Common strengths include 30 mg, 60 mg, 90 mg, 120 mg for immediate-release, and 120 mg, 180 mg, 240 mg, 300 mg, and 360 mg for many extended-release products. Some patients may be prescribed Diltiazem CD 240 mg when a once-daily capsule is appropriate. Specific brands and strengths can vary by manufacturer and by market.

Availability may change over time. Your prescriber may select a formulation that matches your daily schedule and clinical targets.

Missed Dose and Timing

If you miss a dose, take it when you remember the same day. If it is close to your next dose, skip the missed dose and take the next one at the regular time. Do not double up. Keeping a simple reminder system can help you stay on track.

Storage and Travel Basics

Store at room temperature in a dry place away from moisture. Keep the medicine in its original container and out of reach of children and pets. When traveling, carry it in your hand luggage with a copy of your prescription. If your itinerary crosses time zones, keep consistent intervals based on your home schedule until you can confirm a new routine with your clinician. Pharmacies use temperature-controlled handling when required. Avoid storing tablets in a car glovebox or direct sunlight.

Benefits

This therapy can lower blood pressure, reduce angina frequency, and help control heart rate in certain supraventricular rhythms. Extended-release options simplify dosing to once daily for many patients. Stable blood pressure and rate control can support exercise tolerance and daily functioning when combined with lifestyle measures recommended by your healthcare professional.

Side Effects and Safety

• Headache or dizziness, especially when starting
• Flushing or feeling warm
• Swelling of ankles or feet
• Constipation or stomach upset
• Fatigue

Serious reactions are less common but require prompt medical attention. These include slow heart rate, fainting, severe low blood pressure, worsening heart failure, or signs of liver issues such as dark urine or yellowing skin. Seek urgent care for chest pain that changes in pattern or intensity. Risk of low blood sugar may increase when used with insulin or sulfonylureas in people with diabetes due to reduced clearance of some agents; monitoring may be advised by your clinician.

Drug Interactions and Cautions

This medicine can interact with beta-blockers, digoxin, certain statins, cyclosporine, carbamazepine, and drugs metabolized by CYP3A4. Alcohol may intensify blood pressure lowering. Avoid grapefruit products unless approved by your prescriber. If you take anticoagulants such as Warfarin, discuss coordination of care, as clinical monitoring plans can overlap. Learn about related calcium channel blockers in Verapamil Uses.

Tell your clinician about all medicines, vitamins, and herbal supplements. Provide an up-to-date list at each visit and pharmacy fill.

What to Expect Over Time

Blood pressure improvements may appear gradually with steady daily use. Angina symptoms may become less frequent when activity triggers are consistent and the regimen is maintained. For rhythm control, your prescriber may pair this therapy with additional medications or procedures. Keep scheduled follow-ups and lab checks if ordered. Using a home blood pressure log can help your prescriber judge effectiveness and tolerability.

Report new swelling, dizziness, or unusual fatigue. Do not stop abruptly without clinical guidance, as symptoms can rebound in some people.

Compare With Alternatives

Other calcium channel blockers may be considered if you need a different profile. Long-acting nifedipine options such as Nifedipine Xr or brand formulations like Adalat® Xl can be appropriate for some patients. Beta-blockers may be used instead or alongside, depending on your condition and clinician guidance.

Availability and Substitutions

Stock can vary by strength and manufacturer. If a specific item such as Diltiazem 360 mg is unavailable, your prescriber may recommend a therapeutically appropriate alternative dose or a different extended-release brand. Pharmacists will dispense the exact item on your prescription or contact your prescriber for guidance if a substitution is needed.

Patient Suitability and Cost-Saving Tips

Good candidates can take this therapy reliably, monitor for dizziness, and follow up for dose adjustments. People with advanced conduction disease without a pacemaker or severe hypotension are generally not candidates. To reduce costs, consider multi-month fills if your prescriber agrees, and align refills with routine checkups. Set phone reminders for daily dosing to avoid last-minute urgent requests. Review heart-health articles such as Angina Symptoms to support lifestyle planning.

If your plan changes, talk with your clinician before switching forms. For rate control or blood pressure, beta-blockers like Nadolol or Atenolol may be considered based on your history.
