Quinapril
About Quinapril
Quinapril is a prescription medication primarily used to treat high blood pressure (hypertension) and to help manage heart failure. By keeping your blood pressure within a healthy range, it helps lower your long-term risk of experiencing serious cardiovascular events like strokes and heart attacks.
This medicine is typically taken once or twice a day, and it is highly important to take it consistently at the same time every day to maintain stable drug levels in your body. You can take this medication with or without food, though eating high-fat meals might slightly reduce how much of the medicine your body absorbs. Adopting a low-sodium diet and engaging in regular moderate exercise can further enhance the positive results of your treatment.
Many patients taking Quinapril experience only mild side effects, such as a persistent dry cough, headache, or mild dizziness when standing up. However, you must consult your doctor immediately if you face specific serious side effects, such as swelling of your face, lips, tongue, or throat, which can indicate a severe allergic reaction.
Do not take this if you are pregnant, planning to become pregnant, or have a history of severe allergic swelling (angioedema). Talk to your doctor before starting this medicine if you have underlying health conditions such as kidney disease, liver damage, diabetes, or severe dehydration.
This medication can interact with other substances, including certain pain relievers, potassium supplements, and alcohol, which can lead to complications like kidney strain or dangerously low blood pressure. If you are pregnant, breastfeeding, or are an elderly individual, always consult your doctor before starting this treatment to ensure it is safe for your specific situation.

Patients Concern
Disease/Condition Glossary
Hypertension: Also called high blood pressure, is a serious condition in which the force exerted by the blood against the artery walls becomes high. This hardens the heart to pump blood. Raised blood pressure can cause chest pain (angina), heart attack (when the blood supply to the heart is blocked), stroke (brain damage) and kidney failure. Quinapril is used in treating hypertension and thus helps reduce further risk. The blood pressure can be diagnosed with the help of a blood pressure monitor called a sphygmomanometer.
FAQs
Quinapril is used to treat Hypertension.
Quinapril contains Quinapril, which belongs to the Angiotensin-converting enzyme (ACE) inhibitors class. It works by reducing the production of certain substances that cause an increase in blood pressure. This allows the blood to flow more smoothly and makes the heart more efficient at pumping blood throughout the body.
No. Do not stop taking Quinapril without consulting your doctor, even if you feel well or your blood pressure is normal. High blood pressure often has no symptoms, and stopping treatment suddenly may cause your blood pressure to rise again, increasing the risk of heart attack or stroke. Continue taking the medicine as prescribed and speak with your doctor before making any changes to your treatment.
It is advised not to miss any dose of Quinapril. However, if you forget to take a dose of Quinapril, take it as soon as you remember unless it is time for your next dose. Do not double the dose, as it may lead to low blood pressure.
