What is This Medicine? Let us Explain Clearly
Simply put, this medicine combines two different active ingredients into one pill. Both ingredients work together as a powerful team to bring down your high blood pressure.
The first ingredient is Aliskiren, which belongs to a group of drugs called renin inhibitors. Your body naturally produces an enzyme called renin that tightens your blood vessels and raises your pressure. Aliskiren blocks this enzyme so your blood vessels can relax and widen.
The second ingredient is Hydrochlorothiazide, often called HCTZ or a water pill. In medical terms, this is a diuretic that helps your kidneys flush out extra salt and water through your urine. Removing this extra fluid lowers the pressure inside your blood vessels.
Things to Tell Your Doctor Before You Start
Before you take this medicine for the first time, your doctor needs a complete picture of your health history. Tell your doctor right away if you have any of the following medical conditions:
- You have diabetes or high blood sugar levels.
- You suffer from kidney disease or have a history of kidney stones.
- You have any form of liver disease or impaired liver function.
- You suffer from gout or high uric acid levels in your blood.
- You are dehydrated or your body has lost a lot of water and fluids.
- You have experienced an inflammation of your pancreas known as pancreatitis.
- You pass very little urine or struggle with urination problems.
- You are currently pregnant, plan to become pregnant, or suspect you might be pregnant.
- You are a nursing mother breastfeeding your baby.
- You have known allergies to any medicines, foods, dyes, or preservatives.
How Should You Use This Medicine?
