What Tarka is used for
Tarka lowers high blood pressure, which doctors call hypertension.
Tarka modified-release tablets belong to the group of blood-pressure lowering medicines (also called antihypertensives).
Tarka contains two different types of medicines:
- a calcium channel blocker (verapamil)
- an Angiotensin Converting Enzyme (ACE) inhibitor (trandolapril)
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. You may feel fine and have no symptoms, but if high blood pressure is not treated, it can lead to serious health problems. Tarka helps to lower your blood pressure.
Your doctor may have prescribed Tarka for another reason. Ask your doctor if you have any questions about why Tarka has been prescribed for you.
Tarka is not recommended for use in children under the age of 18, as there have been no studies of its effects in children.
This medicine is available only with a doctor's prescription.
There is no evidence that Tarka is addictive.
