What is Norvasc Medication Used For?
Norvasc (amlodipine besylate) is used primarily for the treatment of high blood pressure (hypertension), chronic stable angina (chest pain), and vasospastic (Prinzmetal’s) angina.
By lowering blood pressure, Norvasc helps reduce the risk of heart attacks and strokes.
It works by relaxing blood vessels, allowing blood to flow more easily and the heart to pump more blood.
For angina, Norvasc helps relieve pain caused by reduced blood flow to the heart. It can be used alone or with other medications to treat these conditions. In addition, Norvasc is effective in treating chronic stable angina and vasospastic angina, which are types of chest pain caused by heart issues.
It is also used to reduce the risk of hospitalization and certain procedures in people with coronary artery disease (CAD).
How Does Norvasc Work?
Norvasc relaxes the blood vessels and improves blood flow, helping to lower blood pressure and reduce chest pain.
Amlodipine, the active ingredient in Norvasc, is a calcium channel blocker that prevents calcium from entering the muscle cells of the blood vessels and heart.
This action relaxes the blood vessels, reduces resistance against the heart, and lowers blood pressure.
Norvasc helps reduce the heart’s oxygen demand during physical activity for people with angina, making it easier for the heart to pump. It also helps treat vasospastic angina by blocking the spasm of coronary arteries, restoring normal blood flow.
Dosage Information and Usage
Norvasc dosage varies depending on the treated condition, the patient’s age, and their response to the medication. Your doctor will adjust the dose based on your individual needs.
Dosage Form and Strengths of Norvasc
Norvasc is available in the following strengths and dosage forms:
- 2.5 mg tablets: White, diamond-shaped, flat-faced, beveled-edged with “NORVASC” and “2.5” on opposite sides.

- 10 mg tablets: White, round, flat-faced, beveled-edged with “NORVASC” and “10” on opposite sides.
How to Use Norvasc?
To use Norvasc, take it once a day, with or without food. Taking your dose at the same time each day, such as with breakfast or dinner or at bedtime, is recommended.
If you miss a dose, take it as soon as you remember unless it has been more than 12 hours since your last dose. In that case, wait and take your next dose at the usual time. Do not take more than one dose at a time.
Talk to your doctor if you have any concerns or experience side effects.

Warnings and Precautions
Norvasc is an effective medication for managing high blood pressure and chest pain, but it is important to know certain warnings and precautions when using it.
Some patients may experience specific issues related to their condition, which should be carefully monitored.
- Hypotension (Low Blood Pressure): Norvasc may cause low blood pressure, especially in patients with severe aortic stenosis, where the aortic valve narrows. Since Norvasc has a gradual effect, acute low blood pressure is unlikely, but it is still important to monitor blood pressure regularly.
- Increased Angina or Heart Attack Risk: Some patients may experience worsening chest pain (angina) or even a heart attack after starting or increasing the dose of Norvasc. This is particularly true for those with severe coronary artery disease, where blood flow to the heart is obstructed.
- Patients with Liver Problems: Norvasc is processed by the liver; in people with liver problems, the body may take longer to remove the medication. If you have severe liver impairment, your doctor will need to adjust your dose carefully to avoid potential side effects.
- Peripheral Edema (swelling in the legs and ankles): Some patients may experience lower extremity swelling. This side effect is dose-dependent and may require a dose reduction or discontinuation of the medication.
Drug Interactions With Other Medications
Norvasc can interact with various medications, supplements, or substances, affecting its effectiveness or increasing the risk of side effects.
- CYP3A4 Inhibitors—These medications may increase the plasma concentration of Norvasc, potentially increasing the risk of side effects.
- Ketoconazole
- Itraconazole
- Ritonavir
- CYP3A4 Inducers—These drugs may lower the plasma concentration of Norvasc, potentially reducing its effectiveness.
- Rifampin
- Beta-Blockers: The combination of Norvasc and beta-blockers can have an additive effect on lowering blood pressure and heart rate.
- Metoprolol
- Atenolol
Alternative Medications to Norvasc
If Norvasc is not suitable for you or causes intolerable side effects, there are several alternative medications for high blood pressure and angina.
