Why Is Norvasc?

Amlodipine is the active ingredient in the medication Norvasc. It has been used to treat cardiovascular issues like hypertension (high blood pressure) and angina (chest pain brought on by a disruption in the heart’s blood supply).

Amlodipine is a calcium channel blocker. It obstructs calcium channels, which are unique openings on the surface of cells that allow calcium particles to enter normally. Contractility results from calcium entering the cells that make up the blood vessel walls’ muscles. Amlodipine lowers blood pressure in patients with hypertension. It facilitates the easier pumping of blood throughout the body in patients with cardiac difficulties by blocking the influx of calcium into the cells, inhibiting the blood vessel walls from contracting.

The European Medicines Agency states that all EU nations have used Norvasc to treat angina and hypertension.
This medication may be prescribed by your doctor for different reasons. If you would like additional information on this medication, contact your doctor.

Until you know how this drug affects you, take caution when operating machinery, driving, climbing, or performing other risky actions. Avoid consuming alcohol. Before giving Norvasc to a child, always contact a doctor.

Consult a physician if any of the following apply to you or have previously affected you: allergy to foods, medications, colors, preservatives, or other substances; hepatic illness; heart failure with congestion.


Oral administration of Norvasc is advised, either with or without food and a glass of water. If you also take antacids, waiting at least two hours between taking these medications is preferable. To achieve better results, take the medication daily.

Any medication used in excess might have adverse effects on your health. Get in touch with your healthcare provider right away if you suspect an overdose.

When taken in excess, this medication may result in fainting, extreme dizziness, and rapid heartbeat.

Take the dosage as soon as possible if you forget to take it. Never take two doses at once if your next dose is almost due. Take one dosage at a time.

Norvasc may interact with the following medicines: intravenous (IV) calcium and high blood pressure drugs (diuretics, beta-blockers, and “water pills”), additional drugs for chest pain, such as nitroglycerin.


Give your doctor a complete list of all the medications, herbal remedies, nutritional supplements, and over-the-counter medications you take. Additionally, let them know whether you smoke, take illegal substances, or drink alcohol. Certain things might interfere with your medication.

There could be other negative effects; this is not a complete list. Tell your doctors about all the side effects you notice.

Warning: Unless advised by your physician, avoid using potassium supplements or salt replacements while taking Norvasc. Don’t take it if you are attempting to get pregnant, nursing a baby, or are pregnant. Steer clear of abrupt standing or sitting up, mainly if you are an elderly patient. Your doctor could suggest getting tested for certain conditions (such as renal function or potassium blood level) to track your progress and look for any negative effects.

Regularly check the blood pressure and pulse rate. When taking medication, avoid treating colds, coughs, or pain on your own without first talking to your doctor. Take caution—some substances have the potential to raise blood pressure. Discuss any beneficial lifestyle modifications you may have with your doctor.

Norvasc must be kept in a firmly covered container at room temperature, between 15 and 30 degrees Celsius (59 and 86 degrees Fahrenheit). It must be kept out of light, heat, and moisture and away from animals and children’s reach.
