Dilacor XT Information

Diltiazem CD at CanadaPharmacyOnline.com

The manufacturer of the brand-name Dilacor XT was Watson Pharmaceuticals (United States). The brand Dilacor XT is currently unavailable at this pharmacy.

Important Information about Generic Diltiazem CD

Generic diltiazem CD contains the same active ingredient as brand-name Dilacor XT. It must meet the same effectiveness and quality standards. This means it is designed to work like Dilacor XT. Studies have shown that generic diltiazem CD is bioequivalent to brand-name Dilacor XT, meaning it has similar absorption and achieves comparable blood concentrations. However, individual responses to medication can vary due to factors such as metabolism, genetics, and other health conditions.

Dosage:

Dilacor XT (diltiazem CD) is available in the following once-daily oral strengths at this pharmacy:
• Extended-release capsules: 120 mg, 180 mg, 240 mg, and 300 mg.

The dose is one capsule taken once daily, at the same time each day. Diltiazem CD capsules must be swallowed whole. Do not crush, break, chew, or open the capsule unless your pharmacist specifically advises that the contents may be sprinkled on applesauce. Your doctor selects and adjusts the dose based on your blood pressure or angina control. Do not stop taking Dilacor XT suddenly without first speaking to your doctor.

Usage:

Dilacor XT (diltiazem hydrochloride) is a non-dihydropyridine calcium channel blocker indicated for the treatment of hypertension (high blood pressure) and the management of chronic stable angina pectoris (chest pain). The CD formulation provides once-daily dosing with controlled-release diltiazem throughout the day. It may be used alone or in combination with other antihypertensive agents, such as diuretics.

Unlike dihydropyridine calcium channel blockers (such as amlodipine), diltiazem also slows the heart rate. It slows conduction through the heart, making it particularly suitable for patients who benefit from both blood pressure control and heart rate reduction. Take Dilacor XT daily as directed by your doctor, even when you feel well.

Mechanism of Action
Diltiazem works by blocking calcium from entering the heart and blood vessel muscle cells. This causes blood vessels to relax and dilate, lowering blood pressure and increasing blood flow to the heart. Diltiazem also slows electrical conduction through the atrioventricular (AV) node of the heart, reducing heart rate and decreasing the heart's workload, helping to relieve angina. The controlled-delivery capsule formulation releases diltiazem slowly over 24 hours, enabling once-daily dosing.

Take Dilacor XT exactly as your doctor prescribes, as directed in the product monograph. Swallow the capsule whole unless your doctor or pharmacist instructs otherwise.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Dilacor XT, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Dilacor XT (diltiazem CD). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Dilacor XT; other side effects are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Constipation
• Dizziness, headache, or weakness
• Fatigue or tiredness
• Flushing or skin redness
• Nausea
• Slow heartbeat (bradycardia)
• Swelling of the ankles or feet (edema) (Note: This peripheral edema is a common, localized effect of the medication widening your blood vessels and does not necessarily indicate heart failure; however, it should still be monitored by your doctor).

Serious Side Effects: Seek immediate medical attention or call emergency services if you experience any of the following symptoms:
• Allergic Reaction: Hives, swelling of the face, lips, tongue, or throat, or difficulty breathing.
• Heart Block or Very Slow Heartbeat: A pulse that becomes too slow, severe dizziness, fainting, or loss of consciousness. Diltiazem slows conduction through the heart and can cause heart block, particularly in patients taking beta-blockers or digoxin.
• Heart Failure: Sudden weight gain (specifically defined as a rapid increase of more than 3 lbs in 24 hours or 5 lbs within one week), worsening shortness of breath, or severe ankle swelling. Diltiazem can reduce the heart's pumping strength.
• Jaundice or Liver Problems: Yellowing of the skin or eyes, dark urine, or severe upper stomach pain.
• Low Blood Pressure (Hypotension): Severe dizziness or fainting, especially when standing.
• Severe Skin Reactions: Widespread redness, blistering, or peeling of the skin (Stevens-Johnson syndrome or Toxic Epidermal Necrolysis). Seek emergency care immediately.

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Dilacor XT, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not take Dilacor XT/diltiazem CD if:
• Allergies: You have a known hypersensitivity to diltiazem or any of the capsule's ingredients.
• Acute Myocardial Infarction with Pulmonary Congestion: Do not use if you have recently had a heart attack associated with fluid build-up in the lungs.
• Heart Block: Second or third-degree atrioventricular (AV) block, sick sinus syndrome, or severe bradycardia, unless a functioning dual-chamber pacemaker is in place.
• Severe Hypotension: Systolic blood pressure below 90 mmHg.
• Ventricular Tachycardia (Wide-Complex Tachycardia) or Atrial Fibrillation/Flutter associated with an accessory bypass tract, such as Wolff-Parkinson-White (WPW) syndrome, as diltiazem can dangerously accelerate the heart rate in these patients.

Tell your doctor about all of your medical conditions, past and present, before starting Dilacor XT. This is crucial as certain conditions affect the drug's safety.
• Congestive heart failure — diltiazem can worsen heart function; use with caution
• Diabetes
• If you take digoxin or a beta-blocker, there is an increased risk of bradycardia and heart block.
• If you take ivabradine, an additive that has a heart-rate-lowering effect
• Kidney or liver disease — dose adjustment and monitoring may be required
• Recent heart attack (without pulmonary congestion) — discuss with your doctor.

Drug Interactions:

Before taking Dilacor XT, discuss all potential risks and interactions with your doctor or pharmacist. For complete, up-to-date information, please refer to the product monograph at https://pdf.hres.ca/dpd_pm/00054902.PDF.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Dilacor XT. Dilacor XT may interact with other medicines, including but not limited to:
• Beta-blockers (e.g., metoprolol, atenolol): Combining diltiazem with a beta-blocker can further slow the heart rate and conduction and may worsen heart failure. Use only under specialist guidance with close monitoring.
• Carbamazepine: Diltiazem can raise carbamazepine levels, increasing the risk of toxicity (dizziness, double vision, nausea).
• Cyclosporine: Diltiazem raises cyclosporine levels, increasing the risk of toxicity. Monitor cyclosporine levels closely.
• Digoxin: Diltiazem can raise digoxin levels and further slow the heart rate. Monitor digoxin levels and heart rate closely.
• Grapefruit and Grapefruit Juice: Grapefruit is a potent inhibitor of the CYP3A4 enzyme system. Consuming it while taking diltiazem can significantly increase the drug's concentration in your body, drastically increasing your risk of severe dizziness, dangerous drops in blood pressure, and a dangerously slow heart rate.
• Rifampin: Can significantly reduce diltiazem levels, reducing its effectiveness.
• Statins metabolized by CYP3A4 (e.g., simvastatin, atorvastatin): Diltiazem may raise statin levels, increasing the risk of muscle pain (myopathy) or a rare but severe muscle breakdown condition called rhabdomyolysis. Consider a lower statin dose or a non-CYP3A4-metabolized statin (such as rosuvastatin or pravastatin).

Pregnancy and Breastfeeding:

Dilacor XT should only be used during pregnancy when the benefit clearly outweighs the potential risk to the unborn baby. Animal studies have shown that diltiazem can cause harm to the developing fetus. Contact your doctor immediately if you become pregnant while taking this medication. Diltiazem is excreted in breast milk in concentrations similar to those in the mother's blood. Breastfeeding is not recommended while taking Dilacor XT , as it may pose risks of bradycardia (slow heart rate) or hypotension to the nursing infant. Discuss the risks and benefits with your doctor.

Use in Children:

The safety and efficacy of Dilacor XT in patients under 18 years of age have not been established. It is not recommended for use in children.
