What ZIRCOL 10 and ZIRCOL 20 are used for
The name of your medicine is ZIRCOL 10 or ZIRCOL 20, which is also known as lercanidipine.
ZIRCOL 10 and ZIRCOL 20 belong to a group of medicines called calcium channel blockers (of the dihydropyridine group).
ZIRCOL 10 and ZIRCOL 20 lower high blood pressure, which is also called hypertension. It 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. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
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 eventually hypertension can cause stroke, heart disease and kidney failure. ZIRCOL 10 and ZIRCOL 20 help lower your blood pressure.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor’s prescription.
There is no evidence that this medicine is addictive.
