Uses of Quinapril
Quinapril is used alone or in combination with other medications to treat high blood pressure. It is used in combination with other medications to treat heart failure. Quinapril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Warnings & Precautions
Before taking quinapril:
- tell your doctor and pharmacist if you are allergic to quinapril; other ACE inhibitors such as benazepril (Lotensin, in Lotrel), captopril (Capoten), enalapril (Vasotec, in Vaseretic), fosinopril (Monopril), lisinopril (in Prinzide, in Zestoretic), moexipril (Univasc, in Uniretic), perindopril (Aceon), ramipril (Altace), and trandolapril (Mavik, in Tarka); any other medications; or any ingredients in quinapril tablets. Ask your pharmacist for a list of the ingredients.
- tell your doctor or pharmacist if you are taking valsartan and sacubitril (Entresto) or if you have stopped taking it within the last 36 hours. Your doctor will probably tell you not to take quinapril, if you are also taking valsartan and sacubitril. Also, tell your doctor if you have diabetes and you are taking aliskiren (Tekturna, in Amturnide, Tekamlo, Tekturna HCT). Your doctor will probably tell you not to take quinapril if you have diabetes and you are also taking aliskiren.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: aspirin and other nonsteroidal anti-inflammatory medications (NSAIDs) such as indomethacin (Indocin); diuretics (‘water pills’); lithium (Lithobid); potassium supplements; and tetracycline (Achromycin V, in Pylera). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have ever had swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs while taking quinapril. Your doctor will probably tell you not to take quinapril.
- tell your doctor if you have or have ever had heart, liver, or kidney disease; diabetes; lupus; or scleroderma (a condition in which extra tissue grows on the skin and some organs).
- tell your doctor if you are breastfeeding.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking quinapril.
- you should know that diarrhea, vomiting, not drinking enough fluids, and sweating a lot can cause a drop in blood pressure, which may cause lightheadedness and fainting.
Quinapril comes as a tablet to take by mouth. It is usually taken once or twice a day. To help you remember to take quinapril, take it around the same time(s) 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 quinapril 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 quinapril and gradually increase your dose, not more than once every 1 or 2 weeks.
Quinapril controls high blood pressure and heart failure but does not cure them. Continue to take quinapril even if you feel well. Do not stop taking quinapril without talking to your doctor.
Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to quinapril. Your doctor may order certain lab tests to check your body’s response to quinapril.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
