Generic Name: Amlodipine
Norvasc is a calcium channel blocker (CCB) that contains the active ingredient Amlodipine. It is commonly prescribed to treat high blood pressure (hypertension) and chest pain (angina). Amlodipine works by relaxing and widening the blood vessels, allowing blood to flow more easily throughout the body. This reduces the workload on the heart, lowers blood pressure, and improves the supply of oxygen-rich blood to the heart muscle.
Doctors often prescribe Norvasc as a long-term treatment for hypertension because controlling blood pressure significantly reduces the risk of heart attacks, strokes, kidney disease, and heart failure. The medicine is also effective in managing chronic stable angina and vasospastic (Prinzmetal's) angina by improving blood flow to the heart. Many patients take Norvasc alone, while others may receive it in combination with additional blood pressure medications for better control.
Norvasc is available in 2.5 mg, 5 mg, and 10 mg tablets and is usually taken once daily, making it convenient for long-term use. The medicine can be taken with or without food and should be taken at the same time each day to maintain consistent blood levels. Patients should continue taking Norvasc even if they feel well, as high blood pressure often has no noticeable symptoms.
Although Norvasc is generally well tolerated, regular blood pressure monitoring and routine medical checkups are recommended to ensure the medicine is working effectively. Patients should avoid stopping the medication suddenly without consulting their doctor, as this may worsen their condition. When combined with a healthy diet, regular exercise, reduced salt intake, and smoking cessation, Norvasc helps maintain healthy blood pressure and supports long-term cardiovascular health.
Norvasc is used to treat high blood pressure (hypertension), chronic stable angina, vasospastic (Prinzmetal's) angina, and coronary artery disease (CAD). It helps lower blood pressure, improve blood circulation, reduce chest pain, and decrease the risk of serious cardiovascular events such as heart attacks, strokes, and kidney complications associated with uncontrolled hypertension.
Common side effects of Norvasc include swelling of the ankles or feet (edema), dizziness, headache, flushing, fatigue, nausea, stomach pain, and palpitations. Some patients may experience sleepiness or mild weakness during the initial days of treatment. Rare but serious side effects include severe low blood pressure, allergic reactions, worsening chest pain, irregular heartbeat, or liver problems. Patients should seek immediate medical attention if they experience severe chest pain, difficulty breathing, or swelling of the face or throat.
The dosage of Norvasc depends on the patient's age, blood pressure, and medical condition. Adults are commonly prescribed 5 mg once daily, which may be increased to 10 mg once daily if necessary. Older adults or patients with liver disease may start with 2.5 mg once daily. The tablet should be taken at the same time every day, with or without food, and patients should continue treatment unless advised otherwise by their healthcare provider.
