What this medicine is used for

The name of your medicine is BTC Lercanidipine. It contains the active ingredient lercanidipine (as hydrochloride).

Lercanidipine belongs to a group of medicines called dihydropyridine calcium channel blockers.

Lercanidipine helps lower high blood pressure, otherwise known as hypertension.

This medicine is available only with a doctor’s prescription.

How it works

This medicine works by relaxing some of the blood vessels in the body and reducing resistance to the flow of blood through the blood vessels.

Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. If your blood pressure stays higher than is needed, even when you are calm and relaxed, you have hypertension (high blood pressure).

There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but hypertension can cause stroke, heart disease and kidney failure.

There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children.
