Quinapril can cause injury and possibly death to the fetus when used during pregnancy. If you think you may be pregnant, contact your doctor right away. If you are planning to become pregnant, talk with your doctor about other treatment options.


Quinapril is used for:

Treating high blood pressure alone or with other medicines. It may also be used for other conditions as determined by your doctor.

Quinapril is an angiotensin-converting enzyme (ACE) inhibitor. It works by relaxing blood vessels. This helps to lower blood pressure.

Do NOT use quinapril if:

  • you are allergic to any ingredient in quinapril
  • you are pregnant
  • you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness), including angioedema caused by treatment with an ACE inhibitor
  • you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren

Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with quinapril. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Diuretics (eg, furosemide, hydrochlorothiazide) because the risk of low blood pressure may be increased
  • Everolimus, sirolimus, or temsirolimus because the risk of angioedema may be increased
  • Eplerenone, potassium-sparing diuretics (eg, spironolactone, triamterene), potassium supplements, or trimethoprim because the risk of high blood potassium levels may be increased
  • Aliskiren or angiotensin receptor blockers (eg, losartan) because the risk of certain side effects (eg, kidney problems, high blood potassium levels, low blood pressure) may be increased
  • Insulin, sulfonylureas (eg, glipizide), or other oral diabetes medicines (eg, metformin) because the risk of low blood sugar may be increased
  • Certain gold-containing medicines (eg, auranofin, sodium aurothiomalate) because flushing, nausea, vomiting, and low blood pressure may occur
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen, indomethacin, celecoxib) because they may decrease quinapril's effectiveness and the risk of kidney problems may be increased
  • Lithium because the risk of its side effects may be increased by quinapril

This may not be a complete list of all interactions that may occur. Ask your health care provider if quinapril may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use quinapril:

Use quinapril as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • If you are taking a tetracycline antibiotic (eg, doxycycline) or a fluoroquinolone antibiotic (eg, ciprofloxacin), ask your doctor or pharmacist how to take it with quinapril. This product contains magnesium, which can interfere with absorption of these antibiotics.
  • Quinapril works best if it is taken at the same time each day. Taking quinapril at the same time each day will help you remember to take it.
  • Continue to use quinapril even if you feel well. Do not miss any doses.
  • If you miss a dose of quinapril, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use quinapril.

Important safety information:

  • Quinapril may cause dizziness, light-headedness, or fainting. These effects may be worse if you take it with alcohol or certain medicines. Use quinapril with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Quinapril may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
  • Quinapril may cause a serious side effect called angioedema. The risk may be higher in black patients. Contact your doctor at once if you develop swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness.
  • Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
  • Quinapril may cause a dry, unproductive cough. If caused by quinapril, this symptom usually stops after treatment with quinapril is stopped.
  • Quinapril may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to quinapril. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
  • Check with your doctor before you use a salt substitute or a product that has potassium in it.
  • Dehydration, excessive sweating, vomiting, or diarrhea may increase the risk of low blood pressure. Contact your health care provider at once if any of these occur.
  • Rarely, quinapril may lower the ability of your body to fight infection. This risk may be greater if you have certain other health problems (eg, kidney problems, collagen vascular disease). Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.
  • Quinapril may not work as well in black patients. They may also be at greater risk of side effects. Contact your doctor if your symptoms do not improve or if they become worse.
  • If you have high blood pressure, do not use nonprescription products that contain stimulants. These products may include diet pills or cold medicines. Contact your doctor if you have any questions or concerns.
  • Tell your doctor or dentist that you take quinapril before you receive any medical or dental care, emergency care, or surgery.
  • Diabetes patients - Quinapril may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
  • Lab tests, including blood pressure, blood electrolyte levels, and kidney and liver function, may be performed while you use quinapril. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Use quinapril with caution in the ELDERLY; they may be more sensitive to its effects.
  • Quinapril should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: Quinapril may cause birth defects and fetal or newborn death if you take it while you are pregnant. If you think you may be pregnant, contact your doctor right away. Quinapril is found in breast milk. If you are or will be breast-feeding while you use quinapril, check with your doctor. Discuss any possible risks to your baby.
