Verapamil is a calcium channel blocker that treats several serious health conditions. Doctors use it for high blood pressure, angina, and supraventricular tachycardia. On top of that, it helps prevent migraines and cluster headaches. 

This article covers everything patients should know about verapamil. Readers will also learn about verapamil uses, how it works, proper dosage guidelines, potential side effects, and key precautions to think over while taking this medication.

What is Verapamil?

This medicine belongs to the calcium channel blockers. The drug's action affects calcium movement into heart & blood vessel cells. Your blood vessels widen & heart muscles relax with verapamil. This improves blood flow and helps your heart pump better. Blood pressure drops, chest pain stops, and irregular heartbeats come under control through this mechanism.

Verapamil Uses

Doctors prescribe verapamil to:

• Treat high blood pressure (hypertension)
• Manage angina 
• Control certain heart rhythm disorders
• Prevent cluster headaches 

How and When to Use Verapamil Tablet

• Medical history, including liver or kidney disease, should be discussed before treatment begins.
• Women who are pregnant, trying to get pregnant, or breastfeeding should consult their situation before starting medicine.

How Verapamil Tablet Works

Verapamil prevents calcium ions from moving into arterial smooth muscle and heart cells. Your blood vessels relax and widen as a result, which improves blood flow through your circulatory system. This relaxation brings down blood pressure and helps deliver more oxygen to your heart. The drug also slows down your heart's electrical activity. It also helps control irregular heart rhythms. You can see its antiarrhythmic effects when it stops reentry at the AV node. This helps restore normal sinus rhythm in people with supraventricular tachycardias.

Can I Take Verapamil with Other Medicines?

Verapamil can interact with many medications. You should avoid taking it with:

• Grapefruit juice
• St. John's wort
• Medications for heart rhythm problems
• Certain antibiotics like erythromycin
• Statins 

Paracetamol is the safest painkiller to take with verapamil.

Dosing Information

• Standard doses start at 80-120mg three times daily, with a maximum of 480mg daily. 
• Elderly patients should start with lower doses of 40mg three times daily. 
• Extended-release formulations may need 180-240mg once daily. 

Conclusion

Verapamil serves as the lifeblood medication for many heart-related conditions. This calcium channel blocker helps patients who suffer from high blood pressure, chest pain, and irregular heartbeats. On top of that, it helps many people prevent severe headaches.

This versatile medicine has helped millions of people manage serious health conditions. Success comes from following medical advice, taking doses consistently, and watching for unexpected reactions.
