What is Nifedipine?
Nifedipine is a prescription medication classified as a calcium channel blocker. It works by relaxing and widening your blood vessels, making it easier for blood to flow and reducing the workload on your heart.
What is Nifedipine Used For?
Nifedipine is primarily prescribed to:
- Treat High Blood Pressure (Hypertension): Lowering blood pressure helps prevent complications like strokes, heart attacks, and kidney problems.
- Control Angina (Chest Pain): It can reduce the frequency and severity of chest pain caused by reduced blood flow to the heart.
- Manage Raynaud’s Phenomenon: In some cases, it can help improve circulation and reduce symptoms of Raynaud’s (a condition where blood vessels in the fingers and toes constrict).
How Does Nifedipine Help with Hypertension?
Nifedipine lowers blood pressure through two main mechanisms:
- Blood Vessel Relaxation: It directly relaxes the muscles in your blood vessels, causing them to widen. This reduces resistance to blood flow, leading to a drop in blood pressure.
- Reduced Heart Workload: By relaxing blood vessels, nifedipine lessens the effort your heart needs to pump blood, thus further lowering pressure.
What Are the Side Effects of Nifedipine?
While nifedipine is generally safe, it can cause side effects. Common ones include:
- Dizziness or lightheadedness
- Headache
- Flushing
- Constipation
- Swelling in your feet or ankles
Less common but more serious side effects can occur. Contact your doctor immediately if you experience:
- Fast, irregular, or pounding heartbeat
- Fainting
- Worsening chest pain
- Allergic reactions (rash, itching, swelling)
