Norvasc (Generic Amlodipine)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Norvasc is a brand name for the generic medication amlodipine. It belongs to a class of drugs called calcium channel blockers. Norvasc is primarily prescribed to treat high blood pressure (hypertension) and certain types of chest pain known as angina.
Here’s how Norvasc works:
- Hypertension: Norvasc relaxes and widens the blood vessels, making it easier for the heart to pump blood and reducing the workload on the heart. This helps to lower blood pressure.
- Angina: Norvasc improves blood flow to the heart muscle by relaxing and widening the blood vessels in the coronary arteries. This reduces the frequency and severity of angina attacks and helps to relieve chest pain.
Norvasc is commonly used as a long-term treatment for both conditions. It is usually prescribed in combination with other medications and lifestyle modifications, such as a healthy diet and regular exercise, to effectively manage high blood pressure and angina.
How should this medicine be used?
Norvasc (amlodipine) should be used exactly as prescribed by your healthcare provider. Here are some general guidelines for using Norvasc, but always follow your doctor’s instructions:
- Dosage: Take Norvasc exactly as prescribed. The typical starting dose for adults is 5 mg once daily, which may be increased to a maximum dose of 10 mg once daily if necessary. The dosage for children and adolescents may be different and should be determined by a pediatrician.
- Timing: Norvasc can be taken with or without food. It’s important to take it at the same time each day to help maintain consistent levels of the medication in your body.
- Swallowing: Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet unless specifically instructed to do so by your doctor.
- Compliance: Take Norvasc regularly, even if you feel well. High blood pressure and angina often have no symptoms, and the medication helps to control the conditions. Skipping doses may lead to a rise in blood pressure or increased chest pain.
- Follow-up appointments: Attend all scheduled doctor’s appointments. Your healthcare provider will monitor your response to Norvasc and may adjust your dosage if necessary.
- Other medications: Inform your doctor about all other medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements. Some medications, such as certain antibiotics or antifungal drugs, can interact with Norvasc and affect its effectiveness or increase the risk of side effects.
- Precautions: Before taking Norvasc, inform your healthcare provider about any medical conditions you have, including liver disease, heart disease, or a history of allergic reactions. Norvasc may not be suitable for everyone, and your doctor will consider these factors before prescribing it.
Remember, these guidelines are general information, and individual instructions may vary. Always consult your healthcare provider for personalized advice regarding the use of Norvasc.

What special precautions should I follow?
As for special precautions associated with Norvasc, here are some important considerations:
- Allergic reactions: If you are allergic to amlodipine or any other ingredients in Norvasc, you should avoid taking it. Allergic reactions can range from mild to severe and may include symptoms such as rash, itching, swelling, dizziness, or difficulty breathing. Seek immediate medical attention if you experience any signs of an allergic reaction.
- Pregnancy and breastfeeding: Norvasc should be used with caution during pregnancy, especially during the first trimester, as it may have potential risks to the fetus. It is important to discuss the potential benefits and risks with your doctor if you are pregnant or planning to become pregnant. Norvasc may also pass into breast milk, so breastfeeding mothers should consult their healthcare provider before using the medication.
- Liver disease: Norvasc is primarily metabolized by the liver, so it should be used with caution in individuals with liver disease. Your doctor may need to adjust the dosage or closely monitor your liver function while taking Norvasc.
- Other medical conditions and drug interactions: Inform your doctor about any other medical conditions you have, including heart conditions, kidney disease, or any current medications you are taking. Norvasc may interact with certain medications, including other blood pressure medications, so it’s important to disclose your complete medical history and medication list to your healthcare provider.
