Verapamil is used to treat some types of irregular heartbeat, high blood pressure, angina, and sometimes other conditions. It slows down the electrical activity of your heart which helps to control your heartbeat. It also relaxes blood vessels, which lowers blood pressure and makes it easier for your heart to pump blood around your body.
Take verapamil regularly as directed with a glass of water. You can take it with or without food.
Slow-release tablet: Swallow whole - do not crush or chew.
If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.
Some medicines available without a prescription may react with verapamil including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
