Lisinopril is ace inhibitor?

Yes. Lisinopril is an ACE inhibitor (angiotensin-converting enzyme inhibitor).

What that means:
- It blocks the enzyme that converts angiotensin I to angiotensin II, leading to vasodilation and usually lower blood pressure.
- It’s used for hypertension, heart failure, and after certain heart attacks (MI) to improve outcomes.

Common brand names: Zestril, Prinivil.

Key points:
- Common side effects: cough, dizziness, fatigue; can cause high potassium (hyperkalemia). Rare but serious: swelling of the face/lips/tongue (angioedema).
- Important warnings: avoid in pregnancy (can harm the fetus); use with caution if you have kidney disease or dehydration; NSAIDs can reduce its effectiveness and may worsen kidney function.
- Drug interactions to be aware of: potassium-sparing diuretics or potassium supplements (risk of hyperkalemia), NSAIDs, certain diuretics.

If you’re taking lisinopril and notice a persistent cough, swelling, or any signs of allergic reaction, contact a healthcare provider. If you’re pregnant or planning pregnancy, stop the medication and seek medical advice.
