Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about olmesartan/HCTZ. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking olmesartan/HCTZ against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What this medicine is used for
APO-Olmesartan HCTZ contains two medicines, olmesartan and hydrochlorothiazide (HCTZ). These two medicines work together to treat high blood pressure (hypertension).
Everyone has blood pressure. This pressure helps push blood all around your body. Your blood pressure changes at different times of the day, depending on how busy or worried you are. You have 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 high blood pressure. The only way of knowing that you have high blood pressure is to have your blood pressure checked on a regular basis. Untreated high blood pressure can lead to serious health problems, including stroke, heart disease and kidney failure.
How it works
Olmesartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body which causes blood vessels to tighten. Olmesartan blocks the action of angiotensin-II and therefore relaxes your blood vessels. This helps lower your blood pressure.
HCTZ is a diuretic which reduces the amount of fluid in the body. This also helps to lower blood pressure.
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 olmesartan/HCTZ in children has not been established.

If you do not drink enough water while taking this medicine, you may feel faint, light-headed or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
Tell your doctor if you have excess vomiting and/or diarrhoea while taking this medicine.
You may lose too much water and salt, and your blood pressure may drop too much.
Tell your doctor immediately if you feel light-headed or dizzy after taking your first dose of this medicine, or when your dose is increased.
