Felodipine 10 mg: Everything You Need to Know

Felodipine 10 mg is a prescription medication belonging to the calcium channel blocker class. It is primarily used to treat high blood pressure (hypertension) and help prevent angina (chest pain) by relaxing and widening blood vessels.

By improving blood flow and reducing the workload on the heart, Felodipine helps lower blood pressure and decreases the risk of serious cardiovascular complications such as heart attack, stroke, and kidney damage.

Felodipine is usually prescribed as an extended-release tablet, allowing the medication to work gradually throughout the day.

---

What Is Felodipine 10 mg?

Felodipine is a dihydropyridine calcium channel blocker that relaxes the smooth muscles in the walls of blood vessels.

It is available as:

• Extended-release oral tablets
• Common strengths include 2.5 mg, 5 mg, and 10 mg

The 10 mg tablet is typically used for patients who require stronger blood pressure control after assessment by a healthcare provider.

---

Approved Medical Uses

Healthcare providers prescribe Felodipine for:

• High blood pressure (hypertension)
• Chronic stable angina (chest pain)
• Reducing the risk of cardiovascular complications associated with hypertension

Lowering blood pressure helps protect the heart, brain, kidneys, and blood vessels from long-term damage.

---

How Does Felodipine Work?

Felodipine blocks the movement of calcium into the muscle cells of blood vessel walls.

This helps:

• Relax blood vessels
• Lower blood pressure
• Improve blood flow
• Reduce the heart’s workload
• Help prevent episodes of angina

Unlike some heart medications, Felodipine mainly acts on blood vessels rather than directly slowing the heart rate.

---

How Should Felodipine 10 mg Be Taken?

Always take Felodipine exactly as prescribed by your healthcare provider.

General recommendations include:

• Take once daily.
• Swallow the extended-release tablet whole.
• Do not crush, chew, or split the tablet.
• Take at the same time each day.
• It may be taken with or without food, but try to take it consistently the same way each day.
• Continue taking the medication even if you feel well.

High blood pressure often has no symptoms, so regular treatment remains important.
