Uses

This product is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

This product contains 2 medications: aliskiren and hydrochlorothiazide. Aliskiren works by relaxing blood vessels so blood can flow more easily. It belongs to a class of drugs known as direct renin inhibitors. Hydrochlorothiazide causes your body to get rid of extra salt and water by making more urine. It is called a "water pill" or diuretic.

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start using this product and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once daily. You may take this medication with or without food, but it is important to choose one way and take this medication the same way with every dose. High-fat foods may decrease how well this drug is absorbed by the body, so it is best to avoid taking this medication with a high-fat meal. Also, if you take this drug too close to bedtime, you may need to wake up to urinate. It is best to take this medication at least 4 hours before your bedtime.

Do not take with fruit juices (such as apple, grapefruit, or orange) since they may decrease the absorption of this drug.

If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine, colestipol), take aliskiren/hydrochlorothiazide at least 4 hours before or at least 4 to 6 hours after these medications.

The dosage is based on your medical condition and response to treatment.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to 4 weeks before you get the full benefit of this drug.

Tell your doctor if your condition does not get better or if it gets worse (your blood pressure readings remain high or increase).
