Cardizem (Diltiazem): Uses, Dosage, Safety and Ordering Information
Cardizem contains diltiazem, a calcium-channel blocker that relaxes blood vessels and slows electrical conduction through the heart. It may be prescribed for hypertension, chronic stable angina, or certain supraventricular arrhythmias. Different Cardizem products have different release characteristics, so treatment must be tailored to the diagnosis, heart rate, blood pressure, and other medicines.
Before you buy Cardizem, verify the exact formulation, strength, quantity, and prescription. The Cardizem price can differ by immediate-release or extended-release product, pharmacy, coverage, and generic availability. A pricing difference is not a reason to substitute tablets, capsules, or release forms without prescriber approval.
Indications
Cardizem may be used for high blood pressure, angina, and selected heart-rhythm conditions. It does not treat acute chest pain, stroke symptoms, collapse, or severe shortness of breath. Seek emergency assessment for those symptoms. Blood pressure and pulse monitoring help the clinician determine whether the medicine remains appropriate.
Dosage
Take Cardizem exactly as prescribed. Immediate-release diltiazem tablets may be available as 30 mg, 60 mg, 90 mg, and 120 mg, while extended-release products have their own strengths and directions. You can buy Cardizem 30 mg, buy Cardizem 60 mg, buy Cardizem 90 mg, or buy Cardizem 120 mg only when the prescribed product and strength match. Do not crush or chew an extended-release capsule or tablet unless the pharmacist confirms that the specific product permits it.
Take doses consistently. If a dose is missed, follow the pharmacist’s instructions and never double a dose. Do not stop suddenly without discussing it with the prescriber. The Cardizem price should be compared only for the identical formulation and prescribed quantity.
Safety Information
Cardizem may be unsuitable in severe low blood pressure, sick sinus syndrome without a functioning pacemaker, second- or third-degree AV block without a pacemaker, acute myocardial infarction with pulmonary congestion, or known hypersensitivity. Discuss heart failure, slow pulse, liver or kidney disease, pregnancy, breastfeeding, and planned surgery before treatment.
Dizziness, headache, flushing, swelling, constipation, fatigue, and slow heart rate can occur. Seek urgent help for fainting, severe dizziness, chest pain, new or worsening shortness of breath, marked swelling, very slow or irregular heartbeat, or facial and throat swelling. Avoid alcohol if it worsens low blood pressure or dizziness.
Interactions
Important interactions include beta-blockers, digoxin, antiarrhythmics, statins, cyclosporine, carbamazepine, sedatives, and medicines that affect CYP3A4. Grapefruit can alter diltiazem exposure. Combining medicines that slow heart rate or conduction requires clinical review. Provide a complete list of medicines, supplements, and nonprescription products.
Check with a pharmacist before using cold medicines, pain relievers, or supplements, particularly if they can affect blood pressure, heart rate, or diltiazem metabolism. Keep a record of home blood-pressure and pulse readings if the prescriber requests one, and report readings that are unusually low or symptoms that limit normal activity.
