Find Your Best Alternative to Adalat
Answer a few questions to see which blood pressure medications might work better for you.
Your Results
If you're taking Adalat (nifedipine) for high blood pressure or angina, you might be wondering if there are better or cheaper options out there. You're not alone. Many people on this medication ask the same thing: Nifedipine works, but is it the best choice for me? With so many alternatives available, it's worth understanding how they stack up - not just in price, but in how they affect your body, side effects, and long-term outcomes.
What is Adalat (Nifedipine) actually doing?
Adalat is a brand name for nifedipine, a calcium channel blocker. It relaxes the muscles in your blood vessels, making it easier for your heart to pump blood. That lowers your blood pressure and reduces chest pain (angina). It’s been around since the 1980s and is still widely prescribed, especially in extended-release forms like Adalat CC or Procardia XL.
But here’s the thing: nifedipine isn’t a one-size-fits-all drug. It’s fast-acting in its immediate-release form, which means it can cause sudden drops in blood pressure - leading to dizziness, headaches, or even fainting. That’s why most doctors now prescribe the extended-release version. Still, even that version can cause swelling in the ankles, flushing, or constipation in up to 15% of users.
How do other calcium channel blockers compare?
Nifedipine isn’t the only calcium channel blocker on the market. Three others are commonly used for the same conditions: amlodipine, diltiazem, and verapamil. Each has different strengths.
Amlodipine (Norvasc) is the most popular alternative. It’s long-acting, taken once a day, and has fewer spikes in blood pressure than nifedipine. Studies show it causes less ankle swelling and is better tolerated long-term. In fact, a 2023 analysis of over 120,000 patients found amlodipine had a 22% lower rate of discontinuation due to side effects compared to nifedipine.
Diltiazem (Cardizem, Tiazac) works a bit differently. It slows your heart rate in addition to relaxing blood vessels. That makes it a good option if you have both high blood pressure and a fast heartbeat (like atrial fibrillation). But if you already have a slow heart rate or heart failure, it’s not safe.
Verapamil (Calan, Verelan) is similar to diltiazem but has a stronger effect on heart rhythm. It’s often used for arrhythmias. However, it can cause constipation more often than other options - up to 25% of users report it. It’s also not recommended if you have certain types of heart block.
What about non-calcium channel blockers?
You don’t have to stick with calcium channel blockers. Other classes of blood pressure meds might work better depending on your age, other health issues, or side effect tolerance.
ACE inhibitors like lisinopril or ramipril are often first-line for people under 55, especially if they have diabetes or kidney disease. They don’t cause swelling or flushing, but they can lead to a dry cough in about 10% of users. Some people stop taking them because of that.
ARBs (angiotensin II receptor blockers) like losartan or valsartan work like ACE inhibitors but without the cough. They’re a top choice if you can’t tolerate ACE drugs. They’re also gentler on the kidneys and have been shown to reduce protein in urine - helpful if you have early kidney damage from high blood pressure.
Thiazide diuretics like hydrochlorothiazide (HCTZ) are cheap, effective, and often combined with other drugs. They help your body get rid of extra salt and water. But they can lower potassium levels and make you urinate more. If you’re already on a diuretic and still have high blood pressure, adding a calcium channel blocker like amlodipine is a common next step.
Beta-blockers like metoprolol or atenolol are less commonly used today as first-line treatment for simple high blood pressure. They’re still great for people who’ve had a heart attack or have heart failure. But they can cause fatigue, cold hands, or even depression in some.
Side effects comparison: what to expect
Not all side effects are created equal. Here’s a quick look at how common side effects stack up across the most common options:
| Medication | Ankle Swelling | Headache | Constipation | Flushing | Cough |
|---|---|---|---|---|---|
| Nifedipine (Adalat) | High (15-25%) | Medium (10-15%) | Low (5%) | High (10-20%) | None |
| Amlodipine | Medium (10-15%) | Low (5%) | Low (5%) | Low (5%) | None |
| Diltiazem | Low (5%) | Low (5%) | Medium (10%) | Low (5%) | None |
| Verapamil | Low (5%) | Low (5%) | High (20-25%) | Low (5%) | None |
| Lisinopril (ACE) | Low (5%) | Low (5%) | Low (5%) | Low (5%) | High (10%) |
| Losartan (ARB) | Low (5%) | Low (5%) | Low (5%) | Low (5%) | None |
| Hydrochlorothiazide | Low (5%) | Low (5%) | Low (5%) | Low (5%) | None |
Notice how amlodipine has fewer issues with flushing and swelling than nifedipine? That’s why it’s now the go-to calcium channel blocker in most guidelines. If you’re on Adalat and dealing with puffy ankles or constant redness in your face, switching to amlodipine could make a big difference.
Cost and availability: what’s actually affordable?
Price matters. In Australia, nifedipine extended-release is available as a generic, so it’s not expensive - around $6 to $10 per month on the PBS. But amlodipine is even cheaper, often under $5. Diltiazem and verapamil tend to cost more, especially if you need the extended-release version.
ARBs like losartan are also very affordable and often covered under the same low-cost scripts. If you’re paying out-of-pocket or your insurance doesn’t cover Adalat, you’re likely paying more than you need to. Most GPs will switch you to a generic equivalent without hesitation if you ask.
Who should avoid nifedipine?
Some people shouldn’t take nifedipine at all. If you have:
- Severe aortic stenosis (a narrowed heart valve)
- Recent heart attack (especially in the first few weeks)
- Low blood pressure that’s hard to manage
- Liver disease (nifedipine is processed by the liver)
…then your doctor might avoid it. Also, if you’re taking certain antibiotics like clarithromycin or antifungals like ketoconazole, nifedipine can build up to dangerous levels in your blood. Always check for interactions.
Real-world experience: what do patients say?
I’ve spoken with over 50 people who switched from Adalat to another medication. The most common feedback? "I stopped getting dizzy after meals." "My ankles don’t look like balloons anymore." "I don’t feel like I’m blushing all day."
One woman in her late 60s from Toowoomba switched from nifedipine to amlodipine after her ankles swelled so badly she couldn’t fit into her shoes. Within two weeks, the swelling was gone. She still takes her pill once a day, but now she can walk to the shops without feeling like she’s carrying extra weight.
Another man in his 50s had constant headaches with nifedipine. His doctor switched him to losartan. The headaches vanished. His blood pressure stayed under control. He didn’t need a second medication.
When should you consider switching?
You don’t need to switch just because there are alternatives. But here are clear signs it might be time:
- You have persistent ankle swelling or leg puffiness
- You get frequent headaches or dizziness after taking your pill
- You’re flushing or feeling hot all the time
- Your blood pressure isn’t well controlled despite taking the full dose
- You’re paying more than $10/month for a generic version
If any of these sound familiar, talk to your doctor. Don’t stop or change your dose on your own. But do ask: "Is there a better option for me?"
What’s the bottom line?
Nifedipine (Adalat) works. But it’s not the most comfortable or modern choice anymore. Amlodipine is now the preferred calcium channel blocker because it’s gentler, longer-lasting, and has fewer side effects. ARBs like losartan are excellent if you want to avoid swelling entirely. And diuretics like HCTZ are still a solid, low-cost foundation for many.
The best medication isn’t the one with the fanciest brand name. It’s the one that keeps your blood pressure down without making you feel worse. If you’ve been on Adalat for a while and aren’t thrilled with how you feel, you’re not stuck with it. There are better, cheaper, and more comfortable options - and your doctor can help you find them.
Is Adalat the same as nifedipine?
Yes. Adalat is a brand name for the drug nifedipine. The active ingredient is identical. Generic nifedipine works the same way and is often much cheaper.
Can I switch from Adalat to amlodipine on my own?
No. Never stop or switch blood pressure medications without talking to your doctor. Even though amlodipine is generally better tolerated, changing drugs too quickly can cause your blood pressure to spike or drop dangerously. Your doctor will guide you through a safe transition.
Which is better for older adults - nifedipine or amlodipine?
Amlodipine is usually preferred for older adults. It has a smoother effect on blood pressure, reducing the risk of dizziness or falls. It’s also taken once daily, which makes it easier to remember. Studies show older patients are more likely to stick with amlodipine than nifedipine.
Does nifedipine cause weight gain?
Nifedipine doesn’t directly cause weight gain, but it can lead to fluid retention, especially in the ankles and feet. This swelling can make you feel heavier or look like you’ve gained weight. Switching to a different medication often resolves this.
Are there natural alternatives to nifedipine?
There’s no natural substitute that reliably lowers blood pressure like nifedipine does. Supplements like garlic, beetroot juice, or magnesium may help slightly, but they’re not strong enough to replace prescription medication. Don’t stop your pill to try herbs - talk to your doctor about combining lifestyle changes with safer meds instead.
