What this medicine is used for

APO-Telmisartan HCTZ is used to lower high blood pressure (hypertension).
Everyone has blood pressure. This pressure helps your blood move 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 when your blood pressure stays higher than is needed, even when you are calm or relaxed. There are usually no signs of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis.
Untreated hypertension can lead to serious health problems, including stroke, heart disease and kidney failure.
APO-Telmisartan HCTZ contains both telmisartan and hydrochlorothiazide (HCTZ) in one single tablet. These two active ingredients help to reduce blood pressure in different ways:
Telmisartan belongs to a group of medicines called angiotensin II receptor antagonists. Angiotensin II is a substance in the body which causes blood vessels to narrow, thus increasing blood pressure. Telmisartan works by blocking the effect of angiotensin II. When the effect of angiotensin II is blocked, your blood vessels relax, and your blood pressure goes down
Hydrochlorothiazide belongs to the group of medicines called diuretics. Diuretics help to reduce the amount of excess fluid in the body by increasing the amount of urine produced. They help with lowering blood pressure particularly when used with other blood pressure lowering medicines
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is not addictive.
This medicine is available only with a doctor’s prescription.
The safety and effectiveness of this medicine in children and teenagers up to 18 years of age have not been established.
