About Norvasc
This article provides detailed information about Generic Norvasc (Amlodipine), an oral pill approved in Singapore for the treatment of hypertension and certain forms of angina. As a calcium-channel blocker, it works by relaxing the smooth muscle in blood vessel walls, which helps lower blood pressure and improve blood flow to the heart. The medication is available in 2.5 mg, 5 mg, and 10 mg tablets, offering clinicians flexibility to match the dose to each patient’s needs.
What is Generic Norvasc (Amlodipine)?
Generic Norvasc (Amlodipine) belongs to the dihydropyridine class of calcium-channel blockers. It received approval from the Health Sciences Authority (HSA) of Singapore for the management of essential hypertension and chronic stable angina. The drug is marketed as a tablet (pill) and comes in three strengths-2.5 mg, 5 mg, and 10 mg-allowing dose titration based on therapeutic response and tolerability.
How Norvasc Works
Amlodipine selectively inhibits the influx of calcium ions through L-type calcium channels located on vascular smooth-muscle cells. By reducing intracellular calcium, the drug prevents contraction of these muscles, leading to vasodilation of peripheral arterioles. The resulting decrease in peripheral vascular resistance lowers systolic and diastolic blood pressure. In coronary arteries, the same mechanism improves myocardial oxygen supply, alleviating angina symptoms. Amlodipine’s high lipophilicity gives it a long half-life of about 30-50 hours, permitting once-daily dosing with steady plasma concentrations.
Why Norvasc Is Used for Cardiovascular Conditions
- Hypertension: Lowering systemic vascular resistance directly reduces blood pressure, making amlodipine an effective first-line agent in many guidelines, including those endorsed by Singapore’s Cardiology Society.
- Chronic Stable Angina: By dilating coronary arterioles, the drug enhances oxygen delivery to the myocardium, reducing the frequency of chest pain episodes.
- Coronary Artery Disease (CAD) Prevention: Long-term blood-pressure control slows atherosclerotic progression, lowering the risk of cardiovascular events.
- Raynaud’s Phenomenon (off-label in some regions): Vasodilation can improve peripheral blood flow, though clinical evidence remains limited.
Amlodipine’s once-daily dosing, predictable pharmacokinetics, and low incidence of severe drug interactions position it as a convenient choice compared with older agents such as nifedipine or non-dihydropyridine blockers.
Is Norvasc Right for You?
Norvasc is most suitable for adults who need consistent blood-pressure reduction or relief from angina. It is often chosen for patients who prefer a single daily pill and for those in whom rapid onset is not critical. Special considerations include:
- Elderly patients: The long half-life is advantageous, but clinicians may start with the 2.5 mg dose to minimize edema.
- Renal or hepatic impairment: No dose adjustment is required for mild-to-moderate dysfunction, but monitoring is advised.
- Pregnancy & lactation: Use only if the potential benefit outweighs the risk; data are limited, so the medication is generally avoided unless clearly indicated.
- Contraindications: Severe aortic stenosis, cardiogenic shock, or known hypersensitivity to amlodipine or other dihydropyridines.
Always discuss your full medical history with a healthcare professional before initiating therapy.
Taking Norvasc Effectively
- Timing: Take the tablet at the same time each day, preferably in the morning with or without food. Food does not significantly affect absorption.
- Missed dose: If you remember within 12 hours, take it; otherwise skip and resume your regular schedule. Do not double-dose.
- Travel: Keep tablets in their original container, away from extreme temperatures. For long flights, maintain usual dosing; altitude does not require adjustment.
- Interaction tips: Avoid excessive grapefruit juice, which can increase plasma concentrations modestly. Over-the-counter antihistamines may add to drowsiness; monitor how you feel.
Understanding Side Effects and How to Manage Them
Common side effects arise from the vasodilatory action of amlodipine:
- Peripheral edema: Fluid accumulation, especially in the ankles, occurs because arteriolar dilation raises hydrostatic pressure in capillaries. Elevating the legs, using compression stockings, or combining with a low-dose ACE inhibitor can mitigate this effect.
- Dizziness or light-headedness: Transient blood-pressure drops may cause these sensations, particularly after the first dose. Rise slowly from sitting or lying positions.
- Flushing and headache: Result from rapid vasodilation. Staying hydrated and avoiding extreme heat can help.
- Rare but serious: Sudden chest pain, palpitations, or severe hypotension warrant immediate medical evaluation.
If side effects persist or worsen, contact your healthcare provider; dose reduction or switching to another antihypertensive class may be appropriate.

Frequently Asked Questions
-
How quickly will Norvasc lower my blood pressure? Blood-pressure reduction usually begins within 2 weeks, with the full effect reached after 4-6 weeks of consistent dosing.
-
Can I take Norvasc with other blood-pressure medicines? Yes, it is often combined with ACE inhibitors, ARBs, or diuretics to achieve synergistic control, but a doctor should tailor the regimen.
-
Is the 2.5 mg dose enough for severe hypertension? For most patients, the 2.5 mg dose serves as a starting point. If target blood pressure is not achieved after a few weeks, the dose may be titrated up to 5 mg or 10 mg.
-
Will Norvasc affect my cholesterol medication? Amlodipine has no known pharmacokinetic interaction with statins, making it safe to co-administer with common lipid-lowering agents.
-
Why do I have swelling in my ankles after a few weeks? The swelling is a typical side effect of peripheral vasodilation. Elevating your legs, reducing salt intake, or adding a low-dose ACE inhibitor can alleviate it.
-
Can I stop taking Norvasc abruptly? Stopping suddenly may cause a rebound increase in blood pressure. Any discontinuation should be gradual and supervised by a clinician.
-
Is Norvasc safe for people with diabetes? Yes, it does not adversely affect glucose metabolism and is frequently prescribed to diabetic patients who also have hypertension.
-
What should I do if I miss a dose while traveling across time zones? Maintain the same interval between doses based on your home schedule. If you’re unsure, take the missed dose as soon as you remember unless it’s close to the next scheduled dose.
Glossary

- A class of drugs that inhibit calcium entry into vascular smooth-muscle cells, causing vasodilation and reduced blood pressure.
- Peripheral edema
- Accumulation of fluid in the lower limbs resulting from increased capillary hydrostatic pressure, commonly seen with vasodilators.
- Half-life
- The time required for the plasma concentration of a drug to decrease by 50 %; amlodipine’s long half-life supports once-daily dosing.
- Bioavailability
- The proportion of an administered dose that reaches systemic circulation unchanged; amlodipine has high oral bioavailability (~60-80 %).
- Systolic blood pressure
- The pressure exerted on arterial walls during heart contraction; the primary target for antihypertensive therapy.
