Adalat
Adalat
- Adalat (nifedipine) is a prescription medicine in most countries and is usually dispensed only with a prescription; availability varies by country and some pharmacies or online vendors may sell nifedipine/Adalat without a receipt or prescription, though purchasing without medical oversight is not recommended.
- Adalat is used to treat hypertension and angina (including chronic stable and vasospastic angina). It is a dihydropyridine calcium channel blocker that inhibits Lβtype calcium channels in vascular smooth muscle, causing vasodilation and reduced blood pressure and myocardial oxygen demand.
- Typical adult dosing for extendedβrelease Adalat: start 30 mg once daily, maintenance commonly 60β90 mg once daily (max ~90 mg/day for ER). Immediateβrelease forms are lower (e.g., 10β20 mg) and used less commonly for acute situations; pediatric dosing is weightβbased and requires specialist oversight.
- Given orally as tablets or capsules: extendedβrelease (ER) tablets commonly 30 mg, 60 mg, 90 mg; immediateβrelease capsules/tablets 10 mg and 20 mg; modifiedβrelease forms also available in various strengths.
- Onset of effect depends on formulation: immediateβrelease nifedipine typically begins working within about 20β30 minutes, while extendedβrelease formulations generally start to take effect within 1β2 hours.
- Duration of action varies by formulation: immediateβrelease effects last roughly 4β6 hours, whereas extendedβrelease Adalat formulations are designed for onceβdaily dosing and generally provide control for about 24 hours.
- Avoid or limit alcohol while taking Adalat, as alcohol can enhance bloodβpressure lowering and dizziness and increase the risk of fainting and other adverse effects; consult your clinician about safe use.
- The most common side effect is headache; other frequent effects include flushing, peripheral edema, dizziness/lightheadedness, fatigue, and nausea.

Everyday Use & Best Practices
Morning Vs Evening Dosing
Which time of day should I take Adalat to get steady control but keep side effects low?
For most people on extended-release nifedipine (Adalat ER), the usual starting dose is 30 mg once daily.
Maintenance dosing is often 60β90 mg once daily depending on response and tolerance.
Taking Adalat ER at the same time every day helps keep blood levels steady and reduces the chance of missed doses.
If daytime flushing or headache becomes a problem, discuss switching to evening dosing with your prescriber.
Elderly patients often start at lower doses and titrate more slowly because of increased risk of hypotension.
Pros of Morning Dosing: aligns with daily routines, easier monitoring of daytime blood pressure, and straightforward adherence with morning meds.
Cons of Morning Dosing: may cause daytime flushing or headache for some people.
Pros of Evening Dosing: may reduce daytime side effects and improve tolerance for people with morning sensitivity.
Cons of Evening Dosing: makes it harder to track daytime blood pressure response and may cause nocturnal dizziness in some patients.
- Adherence Tips Checklist: keep tablets in original blister until use, use a pillbox, set phone alarms, record doses in a medication card, and bring BP logs to clinic visits.
Taking With Or Without Meals
Can food change how Adalat works?
Extended-release nifedipine tablets can usually be taken with or without food.
Immediate-release forms may have absorption affected by food, so follow the specific product instructions if you are prescribed those.
Keep ER tablets in their original blister until use and avoid crushing or chewing extended-release tablets.
If a specific product leaflet gives different guidance, follow that leaflet and your prescriber.
Safety Priorities
Who Should Avoid It
Is Adalat safe for everyone?
Absolute contraindications include known hypersensitivity to nifedipine or any excipient.
A history of recent myocardial infarction within two weeks, cardiogenic shock, or severe aortic stenosis makes nifedipine unsafe.
Concurrent use of rifampin is effectively a contraindication because it greatly reduces nifedipine levels and efficacy.
Exercise caution and close monitoring if you have severe hypotension, congestive heart failure, impaired hepatic function, or significant valvular disease.
Pregnant or breastfeeding patients should consult their maternalβfetal medicine specialist or pediatrician before use.
Activities To Limit
What things should I avoid while getting used to Adalat?
| Contraindication / Risk | Monitoring Or Action |
|---|---|
| Known hypersensitivity | Avoid use; seek alternative class. |
| Recent myocardial infarction (β€2 weeks) | Do not start nifedipine; follow cardiology guidance. |
| Cardiogenic shock or severe aortic stenosis | Avoid use and refer to specialist. |
| Concurrent rifampin | Do not combine; rifampin reduces drug levels. |
| Severe hypotension, CHF, hepatic impairment | Use caution, start low, monitor BP, and check liver tests. |
- Limit driving, operating heavy machinery, or climbing ladders until you know how dizziness or lightheadedness affects you.
- Avoid alcohol and very hot baths/saunas early in treatment as they increase vasodilation and dizziness risk.
- Assess falls risk in older adults and remove trip hazards at home.
Dosage & Adjustments
General Regimen
What dose do most people start on?
The standard starting dose for hypertension or chronic stable angina is typically a 30 mg extended-release tablet once daily.
Titration is usually to 60β90 mg once daily as needed to reach blood pressure or angina control.
The maximum daily dose for many ER formulations is commonly 90 mg per day.
Immediate-release strengths such as 10 mg and 20 mg exist but are used less outside acute or inpatient settings.
- Dosing Titration Checklist: start 30 mg ER QD, recheck BP after a week or as advised, increase to 60 mg QD if needed, consider 90 mg QD only with clinician review and monitoring.
Special Cases
How do doctors adjust doses for specific patients?
| Population | Adjustment |
|---|---|
| Elderly | Start lower and titrate slowly due to hypotension risk. |
| Liver Impairment | Reduce dose and monitor hepatic function because nifedipine is hepatically metabolized. |
| Kidney Impairment | Usually no major dose change, but monitor BP and renal status. |
| Pediatrics | Specialist-driven dosing (0.25β0.5 mg/kg/day divided); off-label in many cases. |

Whatβs Inside & How It Works
Ingredients Overview
What is in an Adalat tablet?
The active ingredient is nifedipine, a dihydropyridine calcium channel blocker available in ER strengths of 30 mg, 60 mg, and 90 mg.
Excipients vary by manufacturer; check the product leaflet for specific allergy information.
Bayer AG created the original Adalat brand, and common generic manufacturers include Teva, Sandoz/Novartis, Mylan, Actavis, and Apotex.
Mechanism Basics
How does nifedipine lower blood pressure and reduce angina?
Nifedipine inhibits L-type calcium channels in vascular smooth muscle, causing arterial vasodilation.
This vasodilation lowers systemic vascular resistance and blood pressure and reduces myocardial oxygen demand, which helps in angina.
Extended-release formulations maintain smoother plasma levels and help limit peak-related side effects like sudden flushing or excessive hypotension.
| Active Ingredient | Drug Class | ATC Code |
|---|---|---|
| Nifedipine | Dihydropyridine Calcium Channel Blocker | C08CA05 |
Main Indications
Approved Uses
What conditions is nifedipine approved to treat?
Primary approved indications include hypertension and angina pectoris, including chronic stable and vasospastic angina.
Extended-release nifedipine is commonly used for chronic outpatient management.
Immediate-release nifedipine was historically used in acute care settings but is less favored due to risk of rapid blood pressure drops.
- Hypertension: starting 30 mg ER once daily; maintenance 60β90 mg once daily; typical max 90 mg/day.
- Chronic Stable Angina: 30 mg ER once daily, titrated up to 90 mg if needed.
- Vasospastic Angina: 30 mg ER once daily, titrated as required.
Off-Label Uses
Are there other uses doctors sometimes prescribe nifedipine for?
- Pediatric hypertension in specialist settings, often at 0.25β0.5 mg/kg/day in divided doses under close supervision.
- Some vasospasm disorders and transplant-related hypertension have been managed with nifedipine in specialist care.
- Any off-label use should be confirmed with a specialist and documented with informed consent.
Interaction Warnings
Food Interactions
Can food change how much nifedipine gets into your system?
Regular grapefruit juice intake can increase plasma nifedipine levels and worsen side effects, so avoid or minimize grapefruit products.
Alcohol can increase vasodilation and potentiate dizziness and hypotension; limit intake especially while starting the drug.
Drug Conflicts
Which medications interact significantly with nifedipine?
Strong CYP3A4 inducers like rifampin substantially reduce nifedipine concentrations and are contraindicated.
Strong CYP3A4 inhibitors can increase nifedipine levels and raise side-effect risk; monitor closely if combined.
Caution is needed when combining nifedipine with other antihypertensives, beta-blockers, or nitrates because of additive hypotensive effects.
Always give your prescriber a full medication list, including overβtheβcounter drugs and supplements.
| High-Risk Medication | Interaction |
|---|---|
| Rifampin | Strong CYP3A4 induction; reduces nifedipine efficacy; contraindicated. |
| Strong CYP3A4 inhibitors | Can raise nifedipine levels; increase monitoring for hypotension and side effects. |
| Other Antihypertensives / Nitrates | Additive blood pressure lowering; monitor BP closely. |
Latest Evidence & Insights
What Trials Show (Patient-Focused Summary)
What does the research say about nifedipine ER?
Long-term evidence supports extended-release nifedipine for effective blood pressure control and reducing angina frequency when used appropriately in combination therapy.
ER formulations offer smoother plasma levels and lower the risk of peaks and troughs found with immediateβrelease forms.
Comparative trials place nifedipine among established dihydropyridine options, and choice is often guided by half-life, tolerability, and comorbid conditions.
Practical Clinical Takeaways
- Gradual titration helps minimize dizziness and flushing.
- Monitor for peripheral edema; consider dose reduction, adding a diuretic, or switching drug class if edema is problematic.
- Combine with ACE inhibitor, ARB, or diuretic for multi-drug hypertension regimens as clinically appropriate.
- Use lower starting doses and closer follow-up for older adults and patients with hepatic impairment.
Alternative Choices
Comparable Drugs
Which other drugs work like nifedipine?
Other dihydropyridine calcium channel blockers include amlodipine (Norvasc), felodipine, and nicardipine.
Amlodipine has a longer half-life and may cause less reflex tachycardia in some patients.
Choice among drugs depends on tolerability, dosing convenience, comorbid conditions, and formulary coverage.
When To Switch
How do you know if a switch is needed?
Consider switching if edema is intolerable, flushing is severe, or blood pressure is not controlled despite dose optimization.
Switching should be supervised by a clinician; dose changes and tapering may be advised to avoid rebound symptoms.
Discuss cost, insurance formulary options, and pill availability before making a change.
| Drug | Pros | Cons |
|---|---|---|
| Nifedipine ER | Once-daily dosing, proven efficacy. | Can cause peripheral edema and flushing for some people. |
| Amlodipine | Longer half-life, steady control, once daily. | May still cause edema; different side-effect profile for individuals. |
