Based on FDA data, a significant number of adverse event reports have been received, underscoring the need for careful monitoring. The most critical finding is the risk of angioedema, a serious allergic reaction that can affect the face, lips, tongue, and throat, potentially causing breathing difficulty FDA FAERS ↗.

Safety profile

FDA data includes reports of several side effects associated with lisinopril. The most serious is angioedema, with thousands of reports received FDA FAERS ↗. Other commonly reported side effects include cough, dizziness, and hypotension (low blood pressure) FDA FAERS ↗. Hyperkalemia (elevated potassium levels) is also a known risk, with numerous reports FDA FAERS ↗. Additionally, reports of renal impairment, including acute kidney injury, have been filed FDA FAERS ↗. Each of these side effects has been documented in the FDA adverse event reporting system, with report counts in the thousands for the most frequent events FDA FAERS ↗.

Who should be cautious

Patients with a history of angioedema, including from previous ACE inhibitor use, should avoid lisinopril. Those with kidney disease, diabetes, or who are taking potassium supplements or potassium-sparing diuretics are at higher risk for hyperkalemia FDA FAERS ↗. Pregnant women should not use lisinopril due to risks to the fetus FDA FAERS ↗. Data not available for specific drug interactions beyond those mentioned.

Our recommendation

Based on FDA data, patients taking lisinopril should be monitored for signs of angioedema, such as swelling of the face, lips, or throat, and seek immediate medical attention if these occur. Regular monitoring of blood pressure, kidney function, and potassium levels is essential FDA FAERS ↗. If a persistent cough develops, consult your healthcare provider, as this is a common side effect that may require a medication change FDA FAERS ↗.
