1 What Verapamil tablets are and what they are used for

Verapamil belongs to a group of medicines called calcium-channel blockers which interfere with the electrical signals in the heart muscle and blood vessels. It is used to:

  • manage high blood pressure (hypertension), used alone or with other drugs for high blood pressure.
  • manage and prevent angina.
  • treat and prevent certain types of abnormal heart beats.

3 How to take

Always take Verapamil tablets exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist

Grapefruit juice

Do not eat or drink products containing grapefruit juice whilst taking verapamil, as grapefruit juice increases the effects of verapamil.

Swallow the tablets with water.

  • Angina: Usually 120mg three times a day. For some patients 80mg three times a day may be sufficient.
  • Abnormal heart beats: 40-120mg three times a day.


  • Up to 2 years: 20mg two or three times a day.
  • 2 years and over: 40-120mg two or three times a day.

If you take more than you should

If you (or someone else) swallow a lot of tablets at the same time, or you think a child may have swallowed any contact your nearest hospital casualty department or tell your doctor immediately. Overdose can lead to low blood pressure and in rare cases heart failure.

If you forget to take the tablets

Do not take a double dose to make up for a forgotten dose. If you forget to take a dose, take it as soon as you remember. If it is nearly time for the next dose, skip the missed dose and take the next dose at the right time.
