Diltiazem Tablets for Hypertension

Diltiazem is a calcium channel blocker for hypertension and chronic angina. This page explains dosing, strengths, safety, and access options, including diltiazem price without insurance. Ordering uses a direct route that Ships from Canada to US.

What Diltiazem Is and How It Works

Diltiazem hydrochloride is a nondihydropyridine calcium channel blocker. It decreases calcium entry into cardiac and vascular smooth muscle. This reduces heart rate, lowers vascular resistance, and may improve myocardial oxygen balance. The result can be lower blood pressure and fewer angina episodes.

Approved uses vary by formulation. Immediate-release tablets are used for chronic stable or vasospastic angina. Many extended-release products are approved for treating hypertension in adults. The class also slows atrioventricular nodal conduction, which contributes to its antianginal effect.

Who It’s For

This therapy is intended for adults with essential hypertension, or for chronic stable or vasospastic angina when a calcium channel blocker is appropriate. It is generally not used in severe hypotension, second- or third-degree atrioventricular block, or sick sinus syndrome without a functioning pacemaker. Caution is advised in heart failure with reduced ejection fraction or significant hepatic impairment. Safety and effectiveness in pediatric patients have not been established.

Dosage and Usage

Use exactly as directed by the prescriber and follow the labeled instructions. Swallow extended-release capsules or tablets whole. They can be taken with or without food. Take the medicine at the same time each day to support steady exposure.

For some patients, diltiazem 120 mg once daily may be prescribed. Initiation and any titration depend on the specific release system and clinical response. The official label for each product should guide exact schedules.

Immediate-release tablets are typically taken in divided doses. Do not crush or chew any extended-release formulation. Ask a healthcare professional about alternative formulations if swallowing difficulties occur.

Strengths and Forms

Availability can vary by pharmacy and manufacturer. Common presentations include:

• Immediate-release tablets: 30 mg, 60 mg, 90 mg, 120 mg.
• Extended-release capsules: 120 mg, 180 mg, 240 mg, 300 mg, 360 mg.
• Extended-release tablets: 120 mg, 180 mg, 240 mg, 300 mg.

Brand suffixes such as CD, ER, XR, XT, and LA indicate different extended-release technologies. An example used in practice is diltiazem cd 240 mg. Options differ by labeling and region. For capsule details, see Diltiazem HCL CD.

Missed Dose and Timing

If a scheduled dose is missed, take it when remembered unless it is close to the next dose. If near the next dose, skip the missed dose and resume the regular schedule. Do not double doses. Extended-release products work best when taken at the same time each day.

Storage and Travel Basics

Store at room temperature, typically 20 to 25°C, away from moisture and light. Keep tablets or capsules in the original, child-resistant container with the pharmacy label.

When traveling, keep medicines in carry-on baggage with a copy of the prescription. Avoid leaving containers in parked cars or checked luggage. Consider a simple pill organizer for short trips. For time zone changes, ask a clinician how to adjust the schedule safely.

Benefits

This medicine can help lower systemic blood pressure by relaxing vascular smooth muscle and reducing cardiac workload. Extended-release designs allow once-daily administration for many. The treatment may decrease the frequency of exercise-induced or spontaneous chest discomfort. A broad range of strengths supports tailored therapy under supervision.

Side Effects and Safety

• Headache
• Dizziness
• Flushing
• Edema
• Fatigue
• Nausea
• Constipation
• Palpitations

Serious but less common effects can include slow heartbeat, atrioventricular block, marked hypotension, or liver enzyme elevations. Worsening heart failure may occur in susceptible patients. Seek emergency care for severe chest pain, trouble breathing, fainting, or signs of allergic reaction. All monitoring and adjustments should follow the product labeling.

Drug Interactions and Cautions

This medicine is both a substrate and a moderate inhibitor of CYP3A4. Interactions may involve certain statins, calcineurin inhibitors, benzodiazepines, antiarrhythmics, and anticonvulsants. Simvastatin or lovastatin exposure can increase; prescribers often select alternatives or limit statin dose. Digoxin levels can rise. Grapefruit may raise exposure. Combining with beta blockers such as Atenolol can increase bradycardia or heart block risk.

Review all current prescriptions, nonprescription medicines, and supplements with a healthcare professional before starting or stopping therapy. For broader cardiovascular context, read Lipitor Uses for background on statin therapy and lipid lowering.

What to Expect Over Time

Blood pressure usually responds gradually with regular use. Angina frequency may lessen with consistent therapy and activity moderation as advised. Heart rate reductions can occur, especially at higher exposures or with interacting drugs. Periodic assessments help confirm control and tolerability.

Compare With Alternatives

Other calcium channel blockers can be appropriate for specific scenarios. Dihydropyridine agents such as Nifedipine XR primarily affect the vasculature and may be used when a heart-rate effect is not desired. Another non-dihydropyridine, Verapamil, also slows conduction and can be considered when clinically appropriate. Some patients instead require a beta blocker such as atenolol or metoprolol. Branded once-daily options exist, including Cartia XT generic formulations.

Availability and Substitutions

If a specific strength or release system is unavailable, the prescriber may recommend a therapeutic alternative or a different release design. Branded products such as Cardizem and Cartia XT exist; generics are commonly used when appropriate. Pharmacy stock changes regularly. Restock dates are not guaranteed.

Patient Suitability and Cost-Saving Tips

Ideal candidates include adults with essential hypertension or chronic angina who can adhere to regular dosing and follow-up. Clinicians may avoid this agent in severe hypotension, advanced conduction disease without a pacemaker, acute decompensated heart failure, or significant hepatic impairment.

To reduce out-of-pocket expense, consider a larger fill when appropriate and safe. Multi-month supplies can reduce dispensing fees. Generic selections and consistent release forms help manage costs. Set refill reminders in your calendar. For related therapies, visit Heart Disease.
