Dosage Guide

Quick Answer

Verapamil dose varies by indication (angina, AF, hypertension). SR tablets must always be taken with food and must never be crushed or chewed. Regular BP and heart rate monitoring is essential. Always get the dose from your doctor — NEVER take with beta-blockers (fatal combination). Dose adjustment required in liver disease.

Dose at a Glance

Adult Dose

As prescribed — varies by indication (angina, AF rate control, hypertension)

As prescribed — regular formulations multiple times daily; SR once/twice daily

Max: Do not exceed prescribed limit; liver disease requires dose reduction

Child Dose (As per doctor's advice)

Weight-based dose — consult your doctor

As directed by your doctor

Missed Dose

If you miss a dose, take it as soon as you remember. If the next dose is close, skip the missed dose. Never take a double dose. In cardiac medicines, a double dose can cause severe bradycardia or hypotension.

Overdose

Verapamil overdose is a cardiac emergency. Symptoms include severe bradycardia, severe hypotension, AV block, and cardiac arrest. Go to the EMERGENCY ROOM immediately. Calcium gluconate may be an antidote — given in hospital. Verapamil overdose can be life-threatening.

Verapamil Tablet Dosage (Kitni leni hai)

Verapamil Tablet dose varies by indication and formulation. SR tablets have specific rules — follow them carefully.

Adult Dose (Baalgon ke liye)

As prescribed — indication-dependent
SR tablets must always be taken with food
Monitor BP and heart rate regularly
NEVER take with beta-blockers

Starting Dose: As prescribed by your doctor

Usual Dose: As prescribed (SR formulations preferred for convenience)

Max Daily Dose: Do not exceed prescribed limit; dose reduction required in liver disease

SR Tablets — Critical Rule

SR tablets must never be crushed or chewed. Swallow them whole — always with food. Crushing causes immediate drug release — which can lead to severe hypotension or bradycardia.

Hepatic Dose Adjustment (Liver ki bimari mein)

Verapamil is heavily metabolized by the liver. Dose reduction is required in liver disease — the doctor adjusts based on liver function tests. Do not self-adjust.

Child Dose (Bachon ke liye)

Weight-based dose — consult your doctor

A child's dose is always decided by the doctor based on weight and age.

How to Take (Kaise lena hai)

SR tablets always with food
Never crush/chew (SR)
Regular BP and heart rate monitoring
Avoid beta-blockers

Best Time to Take (Kab lena chahiye)

Maintain consistent daily timing
Tie SR tablet timing to meal time

With Food or Empty Stomach (Khali pait ya khane ke baad)

SR tablets: MUST be taken with food. Regular tablets: with or without food — follow doctor's instructions.

Missed Dose (Dose chhoot jaye to kya karein)

If you miss a dose, take it as soon as you remember. If the next dose is close, skip the missed dose. Never take a double dose — a double dose is dangerous due to cardiac effects.

Overdose (Zyada Dose)

Verapamil overdose is a cardiac emergency — severe bradycardia, AV block, severe hypotension, and cardiac arrest can occur. Go to the EMERGENCY ROOM immediately.

Frequently Asked Questions

Verapamil SR tablets kaise leni chahiye?

SR (slow-release) tablets must always be taken with food — this keeps absorption consistent. Never crush or chew them — crushing causes immediate release, which can lead to severe hypotension or bradycardia. Swallow the tablet whole.

Verapamil aur digoxin ek sath kaise lein?

Verapamil increases digoxin blood levels — raising the risk of digoxin toxicity. When both are taken together, the doctor adjusts the digoxin dose and monitors levels. Do not self-adjust.

Verapamil kitne time mein kaam karna shuru karta hai?

Rate control effects (AF/SVT) occur relatively quickly. Full benefit for angina and BP control develops over a few weeks. Regular monitoring is essential during this period.

Liver disease mein Verapamil kaise lein?

In liver disease, verapamil blood levels can become very high — toxicity is possible at normal doses. The doctor significantly reduces the dose based on liver function. Do not self-adjust.

Verapamil ke sath simvastatin kyun nahi leni chahiye?

Verapamil inhibits the CYP3A4 enzyme, which dramatically increases blood levels of simvastatin and lovastatin — raising the risk of rhabdomyolysis (muscle breakdown). The doctor will reduce the simvastatin dose or switch to a safer statin (pravastatin).
