An angiotensin-converting enzyme (ACE) inhibitor, quinapril treats high blood pressure and heart failure.

To make sure your blood pressure or cardiovascular system in general is maintained properly, follow the instructions provided by your doctor and prescription label.

Keep taking your medication as advised even when you feel fine.

If you don’t feel so good and you have ongoing vomiting, diarrhea, or excessive sweating, call your doctor. Quinapril can easily dehydrate patients, which can lead to excessive low blood pressure, electrolyte disorders, or kidney failure. 

When not using your medication, store it in a place that’s at room temperature and away from moisture, heat, and light.

Please use quinapril carefully.

Do not take the medication if you plan on getting pregnant or have already become pregnant. This medication can cause injury or death to the unborn baby.

Likewise, do not take this medication if you’ve ever had angioedema.

If you have taken medication that contains sacubatril, do not take quinapril within 36 hours before or after. 

If you have diabetes and take medication that contains aliskiren, avoid using quinapril and alert your doctor.

Quinapril can create common side effects, such as headaches, coughing, dizziness, and fatigue.

Serious side effects can include light-headedness, a fast heartbeat, little to no urination, pain during urination, jaundice, numbness/pain in hands/feet, cold or flu symptoms, high potassium symptoms, and low sodium symptoms. If you have dealt with any of these side effects recently, call your doctor right away.
