Nifedipine XR® Tablets for Hypertension

This extended-release calcium channel blocker helps lower blood pressure and prevent chest pain. We make it simple to access Canadian pricing with US delivery from Canada, even without insurance.

What Nifedipine XR Is and How It Works

Nifedipine XR® is an extended-release form of a dihydropyridine calcium channel blocker. It relaxes vascular smooth muscle, which decreases peripheral resistance and eases the workload on the heart. The tablet releases medicine over 24 hours to provide steady control.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This treatment may reduce blood pressure and help prevent episodes of angina. It should not be used for immediate relief of chest pain. For sudden symptoms, follow your clinician’s instructions and emergency guidance.

Who It’s For

This medicine is used in adults for hypertension and for chronic stable or vasospastic angina. It may be part of single or combination therapy when additional control is needed. People with very low blood pressure, shock, or known hypersensitivity to components should avoid it.

Tell your healthcare professional if you have heart failure, liver problems, or have recently had a heart attack. Share a complete list of all medicines and supplements to help prevent interactions. Discuss use during pregnancy or breastfeeding with your prescriber.

Dosage and Usage

Nifedipine extended-release tablets 30 mg are commonly used as a typical starting dose per many labels, taken once daily. Always follow the exact directions on your prescription label. Swallow the tablet whole with water; do not split, crush, or chew. Take at the same time each day to maintain consistent levels.

You may take it with or without food, but be consistent day to day. Avoid grapefruit and grapefruit juice, which can change medicine levels. If your prescriber adjusts the dose, changes are usually made gradually. Do not alter your regimen without medical guidance.

Strengths and Forms

This treatment is supplied as extended-release oral tablets. Common strengths include nifedipine xr 30 mg tablets, plus 60 mg and 90 mg options. Availability may vary by manufacturer and inventory.

Equivalent brand products include Adalat CC or Procardia XL in some markets; we dispense approved generics when appropriate. Your final product may differ in appearance depending on the manufacturer.

Missed Dose and Timing

If you miss a dose, take it when you remember the same day. If it is close to your next scheduled dose, skip the missed one and resume your regular schedule. Do not take two doses at the same time. Setting phone reminders or using a pill organizer can help support steady use.

Storage and Travel Basics

Store tablets at room temperature in the original container, away from excess moisture and light. Keep out of reach of children and pets. Do not use tablets that are damaged or past the labeled date.

When traveling, carry your medicine in hand luggage with a copy of your prescription. Keep the bottle labeled with your name. Time-zone changes usually do not require complex adjustments for once-daily dosing; maintain approximate 24-hour intervals and consult your prescriber if unsure. As a micro-trust note, checkout is encrypted on our site.

Benefits

As a long-acting calcium channel blocker, this therapy supports blood pressure control over 24 hours. Once-daily dosing can simplify routines. For angina, it may help reduce the frequency of episodes during routine activities. Many people tolerate it well, though some effects can occur, especially when first starting.

Side Effects and Safety

• Headache
• Flushing or warmth
• Dizziness or lightheadedness
• Swelling in ankles or feet
• Fatigue
• Nausea
• Palpitations

Serious effects can include very low blood pressure, worsening chest pain in rare cases, or signs of heart failure such as shortness of breath and rapid weight gain. Seek immediate care for severe chest pain, fainting, or allergic reactions. If used with beta blockers or other blood pressure therapies, the risk of low blood pressure can increase.

Drug Interactions and Cautions

Important interactions involve medicines that affect CYP3A, the enzyme that processes this drug. Strong inhibitors (for example, certain azole antifungals, macrolide antibiotics, and some HIV protease inhibitors) may raise levels. Strong inducers (such as rifampin, carbamazepine, phenytoin, and St. John’s wort) may reduce levels and effectiveness.

Grapefruit and grapefruit juice can increase exposure and should be avoided. Combining with other blood pressure medicines may increase dizziness or fainting risk. Use caution with beta blockers and consult your prescriber. For a broader view of heart therapies, see our Cardiovascular category.

What to Expect Over Time

Blood pressure typically improves gradually with steady use. Some people notice early side effects that ease as the body adjusts. Angina prevention effects depend on regular dosing and your overall treatment plan. Keeping a log of readings and symptoms can help your healthcare professional assess progress and adjust other therapies if needed.

Consistency matters. Take your dose at the same time daily, avoid grapefruit, and monitor for dizziness when standing up. If you feel unwell after changes in dose or other medicines, contact your prescriber for guidance.

Availability and Substitutions

We source approved generics from reputable manufacturers. If a specific maker is unavailable, your prescriber may authorize an equivalent extended-release product. We do not guarantee exact pill appearance, as it may vary by supplier. When an item is out of stock, your healthcare professional can suggest an alternative or a short-term substitute from the same class.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults needing once-daily blood pressure control, or those with chronic stable or vasospastic angina. It might not be appropriate for people with very low baseline blood pressure or severe aortic stenosis. Always review your full history with your prescriber.

To manage costs, consider 60- to 90-day refills if appropriate. Align refill dates with appointments to avoid gaps. Compare manufacturers for value, and review your plan’s options if you have coverage. If you pay a cash price, setting reminders and consolidating orders can reduce repeat fees.
