Norvasc 10mg Tablet contains Amlodipine, a calcium channel blocker used to treat high blood pressure and angina. This medication relaxes blood vessels to reduce blood pressure and improve heart blood flow.
Uses
Norvasc treats hypertension (high blood pressure) and chronic stable angina or vasospastic angina. It’s prescribed to reduce cardiovascular risks including heart attack and stroke. Norvasc can be used alone or combined with other antihypertensive medications for optimal blood pressure control.
Benefits
- Effectively lowers high blood pressure
- Reduces risk of heart attack and stroke
- Relieves chest pain from angina
- Improves exercise tolerance in heart patients
- Provides 24-hour blood pressure control with once-daily dosing
- Reduces workload on the heart
- Improves blood flow to coronary arteries
- Well-tolerated with fewer drug interactions
- Suitable for long-term cardiovascular protection
How It Works
Norvasc blocks calcium channels in blood vessel walls and heart muscle, preventing calcium from entering cells. This action relaxes and widens blood vessels, reducing blood pressure and decreasing the heart’s workload. The improved blood flow reduces chest pain and lowers cardiovascular disease risk.
Dosage
Patient Type | Starting Dosage | Maximum Dosage |
---|---|---|
Adults | 5mg once daily | 10mg once daily |
Elderly | 2.5mg once daily | 10mg once daily |
Take Norvasc at the same time each day, with or without food. Swallow tablets whole with water.
Duration of Action
Norvasc begins working within hours, with peak effects occurring 6-12 hours after administration. Its long half-life provides 24-hour blood pressure control with once-daily dosing. Full antihypertensive effects may take 2-4 weeks to develop with consistent use.
Side Effects
Common side effects include ankle swelling, dizziness, flushing, and fatigue. Some patients experience headache, palpitations, or nausea. Gum swelling may occur with long-term use. Most side effects are dose-related and may improve as the body adjusts to treatment.
Warning
Norvasc may cause severe hypotension, especially when starting treatment or increasing doses. Rise slowly from sitting or lying positions to prevent dizziness and falls. This medication is not suitable for treating acute heart attack or unstable angina requiring immediate intervention.
Pregnancy and Breastfeeding
Norvasc should be used during pregnancy only if clearly needed and benefits outweigh potential risks. Limited data exists on pregnancy safety. It’s unknown whether Amlodipine passes into breast milk, so consult healthcare provider before breastfeeding while taking this medication.
Interaction
- Enhanced blood pressure lowering effects with other antihypertensives
- May increase levels of certain cholesterol medications
- Grapefruit juice may increase Amlodipine concentration
- Possible interaction with certain antifungal medications
- May alter effectiveness of some immunosuppressive drugs
Precaution
Use cautiously in patients with severe liver disease, heart failure, or aortic stenosis. Monitor blood pressure regularly, especially during dose adjustments. Elderly patients may be more sensitive to hypotensive effects. Inform dentist about Norvasc use due to potential gum effects.
Important Information
Norvasc is for long-term management and should not be stopped abruptly without medical supervision. Continue taking even when feeling well, as high blood pressure often has no symptoms. Regular blood pressure monitoring and medical follow-ups are essential. Store at room temperature away from moisture and heat.
