This page explains what happens if Furosemide and Lisinopril are taken together, according to official sources.
Risk of hypotension and renal monitoring required
Lisinopril and furosemide (Lasix) are frequently prescribed together for heart failure and high blood pressure. However, blood pressure can drop significantly initially causing dizziness, and renal function and potassium levels require monitoring. Do not stop medications without consulting a doctor.
Do not discontinue medications without clinical advice; maintain hydration and monitor blood pressure, renal labs, and electrolytes.
