Summary
Felodipine is used to treat high blood pressure, which is when the force of blood against your artery walls is too high. By lowering blood pressure, it helps reduce the risk of heart attacks and strokes.
Felodipine is a calcium channel blocker, which works by relaxing blood vessels so blood can flow more easily. This reduces the heart's workload and lowers blood pressure.
The usual starting dose of Felodipine for adults is 5 mg once daily, taken orally. Your doctor may adjust the dose, with a maximum of 10 mg daily.
Common side effects of Felodipine include swelling of the ankles, flushing, and dizziness. These occur in a small percentage of users.
Felodipine can cause low blood pressure, especially when starting treatment. Avoid grapefruit juice, which can increase side effects. It's not recommended for those with severe liver problems or aortic stenosis, which is a narrowing of the heart's aortic valve.
