What is Lisinopril + Hydrochlorothiazide used for?
This medication is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: lisinopril and hydrochlorothiazide. Lisinopril is an ACE inhibitor and works by relaxing blood vessels so that blood can flow more easily. Hydrochlorothiazide is a “water pill” (diuretic) that causes you to make more urine, which helps your body get rid of extra salt and water.
This product is used when one drug is not controlling your blood pressure. Your doctor may direct you to take the individual medications first, and then switch you to this combination product. Do not continue taking the individual medications (lisinopril and/or hydrochlorothiazide) after you start this medication
How should I take Lisinopril + Hydrochlorothiazide?
Take this medication by mouth with or without food as directed by your doctor, usually once daily in the morning. If this medication causes you to urinate more frequently, it is best to take it at least 4 hours before your bedtime to prevent having to get up to urinate.
If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take lisinopril/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.
Use 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.
Tell your doctor if your condition does not get better or if it gets worse (for example, your blood pressure readings remain high or increase).
