Benazepril is an ACE angiotensin converting enzyme inhibitor. ACE is an enzyme in the body which is important for the formation of angiotensin II. Angiotensin II causes constriction of arteries in the body thereby elevating blood pressure. ACE inhibitors such as benazepril lower blood pressure by inhibiting the formation of angiotensin II thus relaxing the arteries. Relaxing the arteries not only lowers blood pressure but also improves the pumping efficiency of a failing heart and improves cardiac output in patients with heart failure.

Benazepril comes as a tablet to take by mouth. It is usually taken once or twice a day with or without food. To help you remember to take benazepril take it around the same time every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part you do not understand. Take benazepril exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of benazepril and gradually increase your dose.

Benazepril controls high blood pressure but does not cure it. Continue to take benazepril even if you feel well. Do not stop taking benazepril without talking to your doctor.

Benazepril is generally well tolerated and side effects are usually mild and transient. A dry persistent cough has been reported with the use of benazepril and other ACE inhibitors. Coughing resolves after discontinuing the medication. Other side effects are rare and include abdominal pain constipation diarrhea dizziness fatigue headache loss of taste loss of appetite nausea and vomiting easy bruising or bleeding chest pain chills difficulty breathing severe dizziness or fainting fever numbness or tingling in the hands or feet rash and a sore or swollen throat. In rare instances liver dysfunction and skin yellowing jaundice have been reported with ACE inhibitors.

Benazepril should not be taken by people with a known allergy to ACE inhibitors. Swelling of the facial tissues and even the upper airways has been reported with ACE inhibitors on very rare occasions and can lead to serious breathing difficulties. Benazepril can interact with diuretics water pills and other blood pressure medicines to cause an excessive drop in blood pressure which can result in symptoms of weakness dizziness and lightheadedness. Worsening of kidney function has been reported with ACE inhibitors especially in patients with severe heart failure or pre-existing kidney disease. Combining benazepril with potassium supplements potassium containing salt substitutes and potassium conserving diuretics such as amiloride Moduretic spironolactone Aldactone and triamterene Dyazide Maxzide can lead to dangerously high blood levels of potassium. Indomethacin Indocin and possibly other anti-inflammatory medications may decrease the blood pressure lowering effect of benazepril.

In rare instances low white blood cell counts have been reported with the use of another ACE inhibitor. Low white blood cells increase the patients risk of infections. When taken with lithium benazepril can increase lithium to toxic levels in the blood. Safe use in children is not established. It is not habit forming.

Benazepril can be used alone in treating high blood pressure. Its blood pressure lowering effect can be further enhanced by the addition of a diuretic medication. Lotensin HCT is an example of a medication which combines the effect of benazepril with a thiazide type diuretic water pill in treating hypertension. By reducing resistance in the arteries benazepril can be useful in the treatment of congestive heart failure.

This medication may be prescribed for other uses ask your doctor or pharmacist for more information.

Tablets should be stored at room temperature in a tightly closed container.
