How to take verapamil
Verapamil comes as standard tablets, slow-release (long-acting) tablets, and a liquid (oral solution).
Slow-release tablets release the medicine gradually into your body. This means you do not need to take them as often.
Swallow your tablets whole with a drink of water. Do not chew or crush them, as it's important that they go into your stomach before they dissolve.
You can take verapamil at any time of day, but try to take it around the same time every day.
If you're taking verapamil as a liquid, it will come with a plastic syringe or spoon to help you take the right amount. If you do not get one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not give you the right amount.
You can take verapamil with or without food.
It's important not to eat grapefruit or drink grapefruit juice while you're taking this medicine. Grapefruit can increase the amount of verapamil in your body and make side effects worse.
