Table of contents:

Monopril, generic name fosinopril, is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure (hypertension). It can be used as an add-on medication for people with heart failure.

Fosinopril works as an ACE inhibitor, which means it blocks the production of angiotensin II, a hormone that narrows blood vessels and raises blood pressure so that blood can flow more easily. By doing so, it helps to relax blood vessels, lower blood pressure, and improve blood flow to the heart. It may be used alone or in combination with other medications.

Uses and Dosage

Fosinopril is taken orally in the form of a tablet, typically once or twice a day. Take it around the same time every day to ensure you remember. Follow the instructions on your prescription label carefully and ask your doctor or pharmacist to clarify anything you are uncertain about.

Do not take more or less of fosinopril than directed by your doctor or take it more frequently. Treatment often begins with a low dose, which may be raised gradually. While fosinopril manages high blood pressure and heart failure, it does not cure either condition. Take it consistently even if you feel well, and do not discontinue without speaking to your doctor.

The standard dosage for Monopril (Fosinopril) depends on the condition being treated.

  • For adults with high blood pressure, the typical dose is between 20 to 40 mg taken orally once a day. For children who weigh over 50 kg, the standard dose is between 5 and 10 mg taken orally once daily.
  • For heart failure, the standard dose is between 20 to 40 mg taken orally once daily. As always, follow your doctor's prescription carefully and do not adjust your dosage or frequency of use without consulting with a healthcare professional.
