Norvasc, which is the brand name of the drug Amlodipine, is a calcium channel blocker of the dihydropyridine-type. The drug works by widening the blood vessels, thereby lowering blood pressure and regulating the circulation of blood. The biological half-life of the drug is about thirty to fifty hours.

Medical Uses

Norvasc may be prescribed for hypertension or high blood pressure, problems related to coronary artery disease, and angina. Other conditions may also benefit from the off-label use of this drug. The medication is approved for treatment in adults and children above the age of six. To ensure that the pills are safe to use, the individual should disclose to the healthcare provider if he or she has any liver disease, heart valve problems, or congestive heart failure. Situations like pregnancy and breast-feeding of a baby should also be checked with through the doctor.

Dosing Guide

Reading the instructions on the prescription label would also be useful in ensuring the drug is administered correctly. The dosage should never be increased or decreased, taken for longer than required or discontinued abruptly as it can increase the risk of side effects and cause the condition to worsen. The drug should be considered as part of the entire treatment that includes diet, exercise, and weight control.

One should not stop taking the drug even if he or she feels better as hypertension does not usually have external symptoms. Regular blood pressure tests and blood tests must be conducted.

Drinking alcohol while on Norvasc can further lower the blood pressure. The patient should not get up from a lying or sitting position too fast as it can make the person feel dizzy.

Individuals allergic to the active ingredient Amlodipine should not take the drug.

Side effects

Common side effects associated with taking Norvasc are headache, dizziness, stomach pain, tiredness, and flushing. Severe adverse reactions that require immediate medical attention are changes in the heartbeat, swelling in the arms and feet, nausea, chest pain, generally feeling unwell, and feeling heavy. Any unusual symptoms, especially if the patient has a serious health condition, should be checked with a healthcare professional immediately.

Interaction with other drugs

Norvasc should be taken by adhering to a few precautions, particularly by being aware of drug interactions. The drug can interact adversely with other blood pressure pills and Simvastatin. It is advisable to keep the doctor informed if the individual is taking this beta blocker with betapace, vitamins, herbal supplements, any prescriptions medications, and over-the-counter pills. Doing so can help prevent harmful drug interactions that can be easily avoided.
