Verapamil is used in case of high blood pressure or angina. It can be taken alone or in combination with other medications to prevent and treat irregular heartbeat.

 

What is Verapamil?

 

Verapamil is a calcium channel blocker drug. It works by relaxing the blood vessels in order to reduce the workload for the heart. It also increases the flow of blood and oxygen to the heart and reduces its electrical activity, thus modulating the heart rate.

 

How should Verapamil be taken?

 

Verapamil can be taken as tablets and extended-release tablets.

The tablet dosage is typically 3-4 doses per day. The extended release formulations must instead be taken once or twice a day, by swallowing them without chewing or breaking them.

 

Relative to the product it may be more suitable to take it in the morning or before bedtime.
