Lisinopril is a medication prescribed to manage high blood pressure (hypertension), heart failure, and improve survival following a heart attack. It belongs to a class of drugs known as angiotensin-converting enzyme (ACE) inhibitors.

Lisinopril is used to treat the following conditions:

• High blood pressure (hypertension)
  
• Heart failure
  
• Post-myocardial infarction (heart attack)
  
  

It may also be prescribed for other cardiovascular conditions as determined by your healthcare provider.

Lisinopril works by relaxing blood vessels, which helps lower blood pressure and improves blood flow, reducing the workload on the heart. This can help manage hypertension and heart failure.

Lisinopril also decreases the amount of sodium and water in the body, which contributes to lower blood pressure.

Lisinopril is typically taken orally once a day, with or without food. Your healthcare provider will determine the appropriate dosage based on your medical condition and response to treatment.

Consult your healthcare provider for specific instructions on how to take lisinopril properly.

The time it takes to see improvements in your condition while taking lisinopril can vary. It may take several weeks to experience the full benefits of the medication. Continue taking lisinopril as prescribed even if you feel well, as sudden discontinuation can lead to your condition getting worse.

While lisinopril is primarily used to lower blood pressure, it may also be prescribed for other purposes, including:

• Diabetic nephropathy (kidney damage from diabetes)
  
• Diabetic retinopathy (eye damage from diabetes)
  
• Migraine prevention
  
• Proteinuria (excess protein in the urine)
  
  

Discuss any alternative uses of lisinopril with your healthcare provider.

Lisinopril is available in various dosage forms, including:

• Oral tablets: Available in strengths ranging from 2.5mg to 40mg.
  
• Oral solution: Available in a concentration of 1mg/mL.
  
  

Generic versions of lisinopril are available under various brand names.

Lisinopril is a prescription medication. You will need a valid prescription from a licensed healthcare provider to obtain this drug.
