Information on Cardizem LA for High Bloodpressure

Cardizem LA is a prescription medication used to treat high blood pressure. The medication is comprised of diltiazem, which is a calcium-channel blocker. Cardizem LA relaxes the blood vessels, thus allowing the heart to not pump as hard and reduce blood pressure. The drug also increases the amount of oxygen and blood flowing to the heart, which further helps fight high blood pressure.

Dosage

• Cardizem LA is brand-name diltiazem and comes in several different dosages, according to MedlinePlus. As of September 2009, the medication was offered in 120 mg, 180 mg, 240 mg, 300 mg, 360 mg, and 420 mg extended-release pills. Most doctors prescribe Cardizem LA to be taken once or twice per day, and may adjust the amount taken over a one to two week period. It can take two weeks for the full effect of Cardizem LA on high blood pressure.

Other Uses

• Cardizem LA and other products containing diltiazem can also be used to prevent angina or chest pain, according to MedlinePlus. However, the medication does not help stop chest pain that has already begun. In addition, Cardizem LA helps control high blood pressure and/or angina but cannot cure either of these conditions.

Precautions

• Women who are pregnant or nursing may not be able to take Cardizem LA and are urged to consult with their doctor, according to MedlinePlus. The medication may interact with other prescription drugs such as benzodiazepine sleeping pills like Versed and Halcion, beta-blockers like Trandate and Toprol XL, antidepressants like BuSpar, the anti-ulcer medication Tagamet, and the anti-seizure medication Tegretol.

Possible Side Effects

• Side effects and allergic reaction can occur with Cardizem LA, according to MedlinePlus. Side effects that only require medical attention if they become severe include the following: flushing, dizziness, headache, weakness, vomiting, slowed heartbeat, diarrhea, constipation, nasal congestion, and coughing. Serious side effects that constitute a medical emergency are as follows: itching, hives, breathing problems, swelling of the lips, tongue, or other parts of the body, unusual bleeding or bruising, flu-like symptoms, and yellow skin or eyes.

Cost

• Most Cardizem LA prescriptions are covered fully or partially by many health insurance programs. The amount the patient must pay is dependent upon his or her health coverage.
