Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
Warning
This medication can cause serious (possibly fatal) harm to an unborn baby if used during pregnancy. It is important to prevent pregnancy while taking this medication. Consult your doctor for more details and to discuss reliable forms of birth control. If you are planning pregnancy, become pregnant, or think you may be pregnant, tell your doctor right away.
Uses
This medication 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, ramipril and hydrochlorothiazide. Ramipril is called an ACE inhibitor and works by relaxing blood vessels so that blood can flow through the body more easily. Hydrochlorothiazide (or "The thiazide diuretic") increases the amount of urine you make, removing extra water and salt from your body. It also helps to relax the blood vessels so that blood can flow through the body more easily.
These medications are used together when one drug is not controlling your blood pressure. Your doctor may direct you to start taking the individual medications first, and then switch you to this combination product if it is the best dose combination for you.
Other Uses
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This drug may also be used for heart failure.
How To Use
Take this medication by mouth with or without food as directed by your doctor, usually once daily. Do not chew or crush the tablet.

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

Use this medication regularly in order 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 several weeks before you get the full benefit of this drug.
