Blood Pressure Medication Comparison Tool
How can we help you compare Plendil options?
Answer these questions to get personalized recommendations for blood pressure medications.
If you’re taking Plendil (felodipine) for high blood pressure, you might be wondering if there’s a better option. Maybe your doctor mentioned alternatives, or you’re dealing with side effects like swollen ankles, dizziness, or headaches. You’re not alone. Many people on Plendil ask the same thing: Felodipine works, but is it the best choice for me?
Felodipine is a calcium channel blocker, a class of drugs that relaxes blood vessels to lower blood pressure. It’s been around since the 1980s and is still prescribed today, especially in places like South Africa where it’s affordable and widely available. But medicine has moved forward. Newer options exist with fewer side effects, different dosing, or better results for certain patients.
How Plendil (Felodipine) Actually Works
Felodipine targets L-type calcium channels in the smooth muscle of your arteries. By blocking calcium from entering these cells, it prevents the muscles from tightening. That means your blood vessels widen, reducing resistance and lowering your blood pressure. It’s a slow-release tablet, so it works steadily over 24 hours. Most people take it once daily, usually in the morning.
It’s not a cure. It doesn’t fix the root cause of high blood pressure - whether it’s stress, salt intake, genetics, or weight. But it keeps pressure down, which reduces your risk of stroke, heart attack, and kidney damage. Studies show it lowers systolic pressure by about 10-15 mmHg and diastolic by 5-10 mmHg on average.
But here’s the catch: it doesn’t work the same for everyone. Some people get great results. Others get side effects without much benefit. That’s why comparing alternatives matters.
Common Alternatives to Plendil
There are four main classes of blood pressure medications doctors use as alternatives to felodipine. Each has different strengths, side effects, and ideal use cases.
1. Amlodipine (Norvasc)
Amlodipine is the most common alternative to Plendil. Like felodipine, it’s a calcium channel blocker - but it’s longer-lasting and more predictable. Many patients switch from Plendil to amlodipine because it’s less likely to cause swelling in the ankles, a frequent complaint with felodipine.
Amlodipine is also cheaper in most places, including South Africa, where generic versions are widely available. It’s usually taken once daily, and its effects last longer than felodipine’s, meaning fewer fluctuations in blood pressure throughout the day.
One study published in the Journal of Human Hypertension in 2023 found that patients on amlodipine reported 30% fewer side effects compared to those on felodipine, especially regarding peripheral edema.
2. Lisinopril (Prinivil, Zestril)
Lisinopril is an ACE inhibitor. Instead of relaxing blood vessels directly, it blocks a hormone called angiotensin II that causes them to narrow. It’s often used for people with diabetes or kidney disease because it protects the kidneys better than calcium channel blockers.
Side effects include a dry, persistent cough - which affects about 10-20% of users. If you’ve ever had a cough that won’t go away on a blood pressure pill, this might be why. But if you don’t get the cough, lisinopril can be very effective. It’s also much cheaper than Plendil in many markets.
Doctors often choose lisinopril for younger patients, those with protein in their urine, or those who need extra heart protection after a heart attack.
3. Losartan (Cozaar)
Losartan is an ARB - angiotensin II receptor blocker. It works similarly to lisinopril but doesn’t cause the dry cough. That makes it a top choice for people who can’t tolerate ACE inhibitors.
It’s also good for patients with a family history of stroke. A major trial called LIFE (Losartan Intervention For Endpoint reduction) showed losartan reduced stroke risk more than atenolol in hypertensive patients with left ventricular hypertrophy.
Side effects are mild: dizziness, fatigue, or elevated potassium levels. It’s not ideal for people with kidney failure or those on potassium supplements. But for most, it’s a clean, effective alternative to Plendil.
4. Hydrochlorothiazide (HCTZ)
HCTZ is a thiazide diuretic - a water pill. It lowers blood pressure by helping your kidneys flush out extra salt and water. It’s one of the oldest and cheapest blood pressure drugs in the world.
It’s often combined with other medications, like losartan or amlodipine, for better results. But taken alone, it’s less effective than calcium channel blockers for moderate to severe hypertension. It’s best for mild cases or when cost is a major factor.
Downsides include low potassium, increased urination, and possible spikes in blood sugar. Diabetics need to monitor closely. But for older adults or those with fluid retention, HCTZ is still a solid first-line option.
Comparison Table: Plendil vs. Common Alternatives
| Medication | Class | Dosing | Common Side Effects | Best For | Cost (South Africa, monthly) |
|---|---|---|---|---|---|
| Plendil (Felodipine) | Calcium Channel Blocker | 5-10 mg once daily | Ankle swelling, flushing, headache, dizziness | Patients needing steady 24-hour control, no kidney disease | R180-R250 |
| Amlodipine | Calcium Channel Blocker | 5-10 mg once daily | Ankle swelling (less than Plendil), fatigue | Patients with edema sensitivity, budget-conscious users | R80-R150 |
| Lisinopril | ACE Inhibitor | 10-40 mg once daily | Dry cough (10-20%), dizziness, high potassium | Diabetics, kidney protection, post-heart attack | R60-R120 |
| Losartan | ARB | 50-100 mg once daily | Dizziness, fatigue, high potassium | Those who can’t take ACE inhibitors, stroke prevention | R100-R180 |
| Hydrochlorothiazide | Diuretic | 12.5-50 mg once daily | Low potassium, frequent urination, elevated blood sugar | Mild hypertension, older adults, fluid retention | R40-R90 |
When to Stick With Plendil
Just because alternatives exist doesn’t mean you should switch. If Plendil is working - your blood pressure is stable, you have no side effects, and you’re not spending too much - there’s no reason to change.
Plendil is especially useful for people with isolated systolic hypertension (high top number, normal bottom number), which is common in older adults. It also has a mild effect on heart rate, which can help if you’re prone to fast heart rhythms.
Some patients do better on Plendil than amlodipine, especially if they’re sensitive to the longer half-life of amlodipine. If you’ve tried amlodipine and felt sluggish or overly low in pressure, Plendil might be your sweet spot.
When to Consider Switching
Switching makes sense if:
- You have persistent ankle swelling - amlodipine or losartan are better choices
- You’re diabetic or have protein in your urine - lisinopril or losartan protect your kidneys
- You’re on a tight budget - HCTZ or lisinopril are far cheaper
- You developed a dry cough on another med - avoid ACE inhibitors, try losartan
- Your blood pressure isn’t controlled - combination therapy (like losartan + HCTZ) may be needed
Never switch on your own. Talk to your doctor. Blood pressure meds aren’t interchangeable like over-the-counter painkillers. Changing drugs without monitoring can cause dangerous spikes or drops.
What Most Doctors in Durban Recommend
In South Africa, cost and availability drive a lot of decisions. Many clinics use amlodipine as the first-line calcium channel blocker because it’s cheaper and better tolerated than Plendil. Lisinopril is common in public hospitals due to its low price and kidney benefits.
But in private practice, doctors often start with losartan for younger patients or those with metabolic syndrome. It’s become the go-to ARB here because it’s effective, has fewer side effects than ACE inhibitors, and is covered by most medical aids.
Plendil is still used - especially for patients who’ve been on it for years and do fine. But new prescriptions? More often than not, it’s amlodipine or losartan.
What You Should Do Next
Don’t panic. Don’t stop your meds. Don’t switch to a friend’s prescription.
Here’s what to do:
- Write down how you feel on Plendil. Are your blood pressure readings stable? Do you get headaches, swelling, or fatigue?
- Check your latest lab results - especially potassium, kidney function, and blood sugar.
- Ask your doctor: "Is there a cheaper or better-tolerated option for me?" Bring your list of side effects.
- If cost is an issue, ask about generic alternatives. Most are just as effective.
- Ask for a blood pressure log. Track your numbers at home for a week. That’s more helpful than one clinic reading.
High blood pressure isn’t a one-size-fits-all problem. What works for your neighbor might not work for you. The goal isn’t to find the "best" drug - it’s to find the right one for you.
Is Plendil better than amlodipine for high blood pressure?
Neither is universally "better." Amlodipine is usually preferred because it’s cheaper, has fewer side effects like ankle swelling, and lasts longer. But some people respond better to Plendil, especially if they experience drowsiness or low blood pressure with amlodipine. The choice depends on your body’s reaction, not just the drug label.
Can I switch from Plendil to losartan on my own?
No. Switching blood pressure medications without medical supervision can be dangerous. Stopping Plendil suddenly can cause a rebound spike in blood pressure. Losartan takes days to reach full effect. Your doctor needs to taper you properly and monitor your levels during the switch.
Why does Plendil cause swollen ankles?
Plendil relaxes small arteries more than small veins. This causes fluid to pool in the lower legs and ankles - a side effect called peripheral edema. It’s more common with felodipine than with amlodipine, which affects both arteries and veins more evenly. Elevating your legs and reducing salt intake can help, but switching meds is often the best fix.
Is there a natural alternative to Plendil?
There’s no natural substitute that reliably lowers blood pressure like Plendil. Supplements like garlic, hibiscus tea, or magnesium may help slightly, but they’re not strong enough for moderate to severe hypertension. Relying on them instead of medication increases your risk of stroke or heart attack. Always use them as complements, not replacements.
How long does it take for Plendil to work?
You may notice lower blood pressure within 2-4 days, but it takes 2-4 weeks for the full effect. The slow-release formula is designed for steady control, not quick drops. Don’t increase your dose if you don’t see results right away - talk to your doctor instead.
Can I take Plendil with other medications?
Plendil can interact with certain drugs. Avoid grapefruit juice - it can spike felodipine levels and cause dangerously low blood pressure. Also, be careful with other blood pressure meds, antifungals like ketoconazole, or antibiotics like clarithromycin. Always tell your doctor about everything you’re taking, including herbs and supplements.
Final Thoughts
Plendil is a solid, proven option for high blood pressure. But it’s not the only one - and for many people, it’s not the best. Amlodipine, losartan, and lisinopril offer similar or better results with fewer side effects and lower costs. Your job isn’t to find the "best" drug. It’s to find the one that fits your life, your body, and your budget. Talk to your doctor. Track your numbers. Ask questions. Your blood pressure shouldn’t be a mystery - it should be under control, quietly and safely.

October 29, 2025 AT 00:51I switched from Plendil to amlodipine last year after my ankles looked like balloons after a long day. Within two weeks, the swelling was gone and my BP stayed steady. Also, amlodipine costs like $5 at Walmart now - no joke. If you’re on Plendil and getting edema, just ask your doc about the switch. No drama, no panic.

October 29, 2025 AT 16:23Interesting that you mention cost, but let’s be real - the entire pharmaceutical industry is a rigged casino. Felodipine was developed by AstraZeneca in the 80s, and now it’s being pushed aside because Big Pharma wants to sell you a newer, pricier version of the same damn molecule. Amlodipine? It’s felodipine’s cousin with a better marketing team. The science hasn’t changed - just the price tag.

October 30, 2025 AT 13:26They don’t want you to know this - but calcium channel blockers like Plendil were designed to mask symptoms so you keep buying meds. The real cause of hypertension? Glyphosate in your food, EMF radiation from 5G, and the government’s secret fluoride agenda. They push amlodipine because it’s cheaper to mass-produce and easier to control the population with. Ask yourself - why does every doctor push the same three drugs? Coincidence? Or is it all connected?

October 30, 2025 AT 21:41For anyone reading this and feeling overwhelmed - you’re not alone. I’ve helped over 200 patients switch meds safely. The key is patience and tracking. Write down your BP readings twice a day for a week before your appointment. Bring your list of side effects. Ask: ‘What’s the goal here - cost, tolerance, or organ protection?’ Don’t let them rush you. Your body is the experiment - you’re the scientist.
And if cost is a barrier, ask for samples. Many reps still hand them out. You’d be shocked how often they say yes.

October 31, 2025 AT 08:48Let’s cut the corporate fluff. Plendil’s a glorified vasodilator with a side of ankle-fluff. Amlodipine? Same molecular family, better pharmacokinetics, less edema, cheaper as hell. Lisinopril’s the OG for diabetics - but if you cough like a chain-smoker on a fog machine, you’re not ‘sensitive,’ you’re just allergic to ACE inhibitors. Losartan? The smooth operator. No cough, decent stroke protection, and it doesn’t make you feel like a zombie. HCTZ? The grandpa of BP meds - still works, but don’t be surprised when your potassium drops faster than your ex’s text replies. Bottom line: stop romanticizing Plendil because your grandpa took it. Medicine isn’t nostalgia - it’s data. And the data says: upgrade.
