Verapamil Hcl (Verapamil Hci) Buyer and Patient Handbook in Singapore

What is Verapamil Hcl?

Verapamil Hcl is a calcium-channel blocker used primarily to treat Hypertension, Angina pectoris, and certain cardiac arrhythmias. It belongs to the class IV anti-arrhythmic group and works by relaxing the smooth muscle in blood vessels and the heart. The medication is supplied as oral pill tablets and is approved by the Health Sciences Authority (HSA) of Singapore.

Who Should Use Verapamil Hcl?

• Adults diagnosed with High Blood Pressure who need additional blood-pressure control.
• Patients with chronic stable angina who require reduction of chest-pain episodes.
• Individuals with supraventricular tachycardia or Atrial Fibrillation where rate control is indicated.
• Those who have not achieved target outcomes with first-line agents (e.g., ACE inhibitors, β-blockers).

How Does It Work?

Verapamil blocks L-type calcium channels in vascular smooth muscle and the cardiac conduction system. By preventing calcium influx, it dilates arteries, lowers peripheral resistance, and slows electrical conduction through the AV node, resulting in reduced heart rate and blood-pressure. Think of it as a traffic controller that eases the flow of “calcium vehicles,” preventing congestion that would otherwise raise pressure and speed.

Why Choose Verapamil Hcl?

• Effective rate control for atrial arrhythmias where β-blockers are unsuitable.
• Demonstrated relief of angina symptoms through coronary vasodilation.
• Generic formulation offers cost savings without compromising bioequivalence.
• Available in two convenient strengths (40 mg and 120 mg), allowing flexible dosing.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

• 40 mg tablet: typically taken 1-3 times daily for hypertension.
• 120 mg tablet: commonly prescribed 1-2 times daily for angina or Arrhythmia control. Dose adjustments are made based on clinical response and tolerability.

How to Take

• Swallow the tablet whole with a full glass of water.
• Can be taken with or without food; however, taking it with meals may reduce gastrointestinal upset.
• Maintain a consistent schedule each day to keep blood levels stable.

Missed Dose

• If the scheduled dose is missed and less than 6 hours remain before the next dose, take the missed tablet.
• If more than 6 hours have passed, skip the missed dose and resume the regular schedule.
• Do not double-dose to make up for a forgotten tablet.

Overdose

• Seek immediate medical attention if two or more tablets are taken unintentionally.
• Symptoms may include severe hypotension, bradycardia, or fainting.
• Provide emergency personnel with the exact amount ingested and time of overdose.

Special Populations

• Elderly: Start at the lower 40 mg dose; monitor blood pressure and heart rate closely.
• Renal impairment: No dose change required for mild-moderate impairment, but severe impairment warrants careful monitoring.
• Hepatic impairment: Consider dose reduction; avoid in severe liver disease.

Lifestyle & Diet

• Avoid grapefruit juice as it can increase Verapamil plasma concentrations.
• Moderate alcohol intake; excessive drinking may amplify blood-pressure-lowering effects.
• Continue regular physical activity, but inform your clinician if you experience dizziness or palpitations during exercise.

Precautions and Warnings

• Hypotension: Monitor blood pressure after the first dose; stand up slowly to reduce dizziness.
• Bradycardia: Check heart rate regularly; adjust dose if resting heart rate falls below 50 bpm.
• Heart-block: Use with caution in patients with existing AV-node dysfunction.
• Concurrent β-blockers: May cause additive bradycardia; dose titration is essential.

Frequently Asked Questions

How long does it take for Verapamil to lower my blood pressure?

Most patients notice a reduction within 2-4 hours after the first dose, with the full effect developing over several days of consistent use.

Can I take Verapamine with my daily coffee?

Yes, moderate coffee consumption does not significantly affect Verapamil levels. Excessive caffeine may increase heart rate, so monitor how you feel.

Is it safe to use Verapamil while pregnant?

Verapamil is category C in Singapore; it should only be used if the potential benefit justifies the potential risk to the fetus. Discuss with your obstetrician.

What should I do if I feel unusually dizzy after a dose?

Sit or lie down immediately, avoid standing quickly, and contact a healthcare professional if dizziness persists or is accompanied by fainting.

Can Verapamil cause weight gain?

Weight gain is not a typical side effect, but fluid retention (edema) may occur in some individuals, especially at higher doses.

Does Verapamil interact with OTC cold medicines?

Some decongestants (e.g., pseudoephedrine) can raise blood pressure and counteract Verapamil’s effect. Use caution and check labels.

I missed several days of medication-should I restart at a lower dose?

If you missed more than 2 days, resume the prescribed dose but monitor blood pressure and heart rate closely for the first 48 hours. If unsure, contact a clinician.

Are there any herbal products I should avoid?

St. John’s wort induces CYP3A4 and may reduce Verapamil levels, potentially decreasing effectiveness.

Glossary

• Calcium-channel blocker: A drug that inhibits calcium entry into cells, causing blood vessels to relax and heart rate to slow.
• AV node: A part of the heart’s electrical system that regulates the timing of each heartbeat.
• CYP3A4: An enzyme in the liver that metabolises many medicines; inhibitors can raise drug concentrations.
