Lisinopril Dosing by Indication

Lisinopril is dosed differently depending on the condition being treated. The starting dose for [hypertension](/conditions/hypertension) is much lower than the starting dose for [heart failure](/conditions/heart-failure), and the target dose for post-MI is different again. Using the wrong dose range can result in inadequate treatment or unnecessary side effects.

Hypertension (High Blood Pressure)

ParameterDose
Starting dose (most patients)10 mg once daily
Starting dose (elderly, volume-depleted, or CKD)5 mg once daily
Usual maintenance dose20–40 mg once daily
Maximum dose80 mg once daily (rarely needed)
Dose adjustment frequencyEvery 2–4 weeks based on blood pressure response

Heart Failure with Reduced Ejection Fraction (HFrEF)

For heart failure, the target dose is much higher than for hypertension. Evidence from the ATLAS trial shows that higher doses of [lisinopril](/drugs/lisinopril) (32.5–35 mg/day) are associated with better outcomes than lower doses (2.5–5 mg/day). The key is to titrate up as tolerated.

ParameterDose
Starting dose2.5–5 mg once daily
Target dose20–40 mg once daily
Maximum dose40 mg once daily
TitrationDouble dose every 2 weeks as tolerated; hold if systolic BP <90 mmHg or creatinine rises >30%

Post-Myocardial Infarction (Post-Heart Attack)

ParameterDose
Starting dose (within 24 hours of MI)5 mg, then 5 mg at 24 hours, then 10 mg at 48 hours
Maintenance dose10 mg once daily
DurationAt least 6 weeks; indefinitely if LV dysfunction present

Diabetic Nephropathy

ParameterDose
Starting dose10 mg once daily
Target dose20–40 mg once daily
GoalReduce proteinuria; slow CKD progression

Renal Dosing Adjustments

eGFR (mL/min/1.73m²)Starting Dose Adjustment
≥30No adjustment needed
10–30Start at 5 mg once daily
<10 (including dialysis)Start at 2.5 mg once daily; titrate carefully

Pediatric Dosing (Hypertension, Age ≥6 Years)

Starting dose: 0.07 mg/kg once daily (up to 5 mg). Maximum dose: 0.61 mg/kg (up to 40 mg) once daily. Lisinopril is not recommended in children under 6 years or with eGFR <30 mL/min/1.73m².

Important Dosing Notes

  • Lisinopril can be taken with or without food
  • Take at the same time each day for consistent blood pressure control
  • Check potassium and creatinine 1–2 weeks after starting or increasing the dose
  • A rise in creatinine of up to 30% is acceptable; >30% warrants dose reduction or discontinuation
  • Do not take a double dose if you miss a dose — skip the missed dose and take the next scheduled dose
