Prinivil is a prescription medication primarily used to lower high blood pressure (hypertension). It can also be prescribed to treat heart failure or to reduce the risk of heart attack in people with a history of heart disease. It is also used to treat heart failure and to improve survival after a heart attack.
Prinivil contains lisinopril, which belongs to a class of drugs called ACE (Angiotensin Converting Enzyme) inhibitors. Lisinopril works by relaxing blood vessels, which helps to improve blood flow and lower blood pressure.
Uses and Dosage
Lisinopril comes in the form of tablet to take by mouth with or without food as directed by your doctor, usually once daily. It may take 2 to 4 weeks before you get the full benefit of this medication. For the treatment of heart failure, it may take weeks to months before you get the full benefit of this medication.
The dose of lisinopril for adults is typically prescribed once a day, with or without food, and ranges from 2.5 mg to 40 mg daily depending on the condition being treated. People who take other medications that lower blood pressure or have kidney disease may require lower doses. It may take up to 2 weeks to see the full effects of the medication. The dose of lisinopril for children is determined by their body weight. Children weighing 20 to 50 kilograms usually start with 2.5 mg once daily, which may be gradually increased to a daily dose of 20 mg. Children weighing more than 50 kilograms typically start with 5 mg once daily, which may be gradually increased to a daily dose of 40 mg.
Take the tablet exactly as prescribed by your doctor. If you miss a dose of the tablet, do not take a double dose to make up for it. Instead, skip the missed dose and continue with your regular dosing schedule as prescribed by your doctor. If you are uncertain about what to do after missing a dose, seek advice from your doctor or pharmacist.
