Lisinopril is a medication commonly used to treat high blood pressure (hypertension) and heart failure. It can also help improve survival after a heart attack. Lisinopril belongs to a class of drugs known as ACE inhibitors, which work by relaxing blood vessels, making it easier for the heart to pump blood.

Here are a few key points about lisinopril:

- **Usage**: It's typically taken once a day, and you should follow your healthcare provider's instructions regarding dosage.
- **Side Effects**: Some common side effects include cough, dizziness, and headache. If you experience severe side effects like swelling of the face, lips, or throat, you should seek medical attention immediately.
- **Interactions**: Lisinopril can interact with other medications, including diuretics and potassium supplements. It's important to discuss all medications you're taking with your healthcare provider.
- **Monitoring**: Regular monitoring of blood pressure and kidney function is usually recommended while taking lisinopril.

Always consult your doctor or pharmacist for more information specific to your health condition and treatment plan.
