Quinapril Dosing

The recommended starting quinapril dosage for treating high blood pressure is 10 mg or 20 mg once daily or divided into two smaller doses (5 mg to 10 mg twice daily). For treating congestive heart failure, the starting quinapril dose is 5 mg twice daily. Some considerations with quinapril dosing include the importance of taking your quinapril as prescribed, taking it at the same times every day to maintain even levels of the drug in your blood, and never taking a double dose of quinapril (even if you miss a dose).

 

Quinapril Dosing: An Introduction

The dose of quinapril hydrochloride (Accupril®) your healthcare provider recommends will vary depending on a number of factors, including:
 
  • Your age
  • The medical condition you are being treated for
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
 

Quinapril Dosing for High Blood Pressure

The recommended starting dosage of quinapril for most people with high blood pressure (hypertension) is quinapril 10 mg or 20 mg once daily or divided into two smaller doses (quinapril 5 mg to 10 mg twice a day). Based on the blood pressure response and/or quinapril side effects, the dosage may be increased or decreased. With each change in dosage, it may take several weeks to see the full effects of quinapril on lowering blood pressure.
 
If you have high blood pressure and are already taking a diuretic (water pill), have kidney disease, or are older, your healthcare provider may choose to start you on a lower dose of quinapril, such as quinapril 5 mg.
 

Quinapril Dosing for Congestive Heart Failure

The recommended starting dosage of quinapril for most people with congestive heart failure is quinapril 5 mg twice a day. Based on the response and/or quinapril side effects, the dosage may be increased or decreased. Most people take an average of 20 mg to 40 mg a day, divided into two equal doses (quinapril 10 mg to 20 mg twice a day).
