Felodipine: What It Is, How It Works, and What You Need to Know

When your doctor prescribes felodipine, a long-acting calcium channel blocker used to lower blood pressure by relaxing blood vessels. Also known as a dihydropyridine calcium antagonist, it works by stopping calcium from entering the muscle cells in your heart and arteries, which lets your blood vessels widen and your heart work less hard. Unlike some blood pressure drugs that slow your heart rate, felodipine mainly targets your arteries—making it a go-to for people who need steady pressure control without drowsiness or fatigue.

Felodipine doesn’t work alone. It’s often paired with other antihypertensive, medications that reduce high blood pressure. Also known as blood pressure medication, these include diuretics, ACE inhibitors, or beta-blockers—each filling a different role in managing your cardiovascular health. If you’re on felodipine, you’re likely managing chronic hypertension, not just a one-time spike. It’s not a quick fix. You take it daily, often for years, to keep your arteries flexible and your heart from overworking. Many people confuse it with short-acting drugs like nifedipine, but felodipine is designed for smooth, 24-hour coverage. That’s why it’s preferred for long-term use: fewer spikes, fewer side effects like flushing or dizziness.

It’s not for everyone. If you have severe liver disease, your body can’t break it down well. If you’re pregnant or have a history of heart failure, your doctor will think twice. And while it’s generally well-tolerated, some users report swollen ankles, headaches, or a weird taste in their mouth—side effects that often fade after a few weeks. What’s interesting is how often it shows up in combination with other drugs in real-world use. You’ll find posts here that compare it to amlodipine, look at its effects on kidney function, and even explore how it interacts with grapefruit juice (yes, that’s a real thing—grapefruit can spike its levels dangerously).

You’ll also see posts about how it fits into broader heart health strategies—like what to eat while on it, how to monitor your pressure at home, and why skipping doses can undo months of progress. This isn’t just a drug guide. It’s a collection of real experiences, clinical insights, and practical tips from people who’ve lived with high blood pressure and found felodipine works for them. Whether you’re just starting out or have been on it for years, the posts below give you the unfiltered details you won’t get from a pamphlet.
