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.

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.

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 take this drug too close to bedtime, you may need to wake up to urinate. It is best to take this medication when you first wake up for the day. Consult your doctor or pharmacist if you have questions about your dosing schedule.

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.

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

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.

Do not stop taking this medication without first consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased.

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

Dizziness or lightheadedness may occur as your body adjusts to the medication. Headache or dry cough may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
