Lisinopril: Uses, Dosage, Side Effects & Interactions

When working with lisinopril, an ACE inhibitor that lowers blood pressure and protects the heart. Also known as Prinivil or Zestril, it blocks the renin‑angiotensin‑aldosterone system to keep blood vessels relaxed. This action makes it a go‑to choice for Hypertension, a condition where the force of blood against artery walls stays too high. By easing that pressure, lisinopril also helps prevent Heart Failure, the weakening of the heart’s pumping ability caused by long‑term high blood pressure and can slow the progression of chronic kidney disease. In short, lisinopril encompasses treatment for high blood pressure, shields the heart, and supports kidney function.

Key Benefits and Considerations

One of the biggest advantages of lisinopril is its once‑daily dosing, which fits most people's routines. Typical adult doses start at 10 mg per day and may be increased to 40 mg, depending on blood‑pressure goals and kidney function. For seniors or patients with reduced kidney clearance, doctors often begin at 5 mg to avoid sudden drops in pressure. The drug’s predictable half‑life (about 12 hours) means steady blood‑pressure control without frequent adjustments.

Side effects are usually mild: a dry cough, light‑headedness, or occasional dizziness, especially after the first few doses. Rarely, patients develop angio‑edema—swelling of the lips, tongue, or throat—which requires immediate medical attention. Because lisinopril can raise potassium levels, it’s important to monitor blood tests if you’re also taking potassium‑rich foods or supplements. Interactions are common with NSAIDs, certain diuretics, and other blood‑pressure medicines, so always share your full medication list with your clinician.

Monitoring is a simple but critical part of therapy. Your doctor will check blood pressure, kidney function (creatinine), and electrolytes within the first few weeks, then periodically thereafter. Adjustments are made based on these labs and how you feel—if you notice persistent dizziness or a nagging cough, bring it up right away. The goal is a steady, safe blood‑pressure range without compromising kidney health or causing uncomfortable side effects.
