📌 Quick Answer: Lisinopril starting dose for hypertension is 10 mg once daily (5 mg if on a diuretic). Heart failure starts at 5 mg daily (2.5 mg if hyponatremic). Post-MI: 5 mg → 5 mg → 10 mg daily. CrCl 10-30: halve the usual starting dose. CrCl <10 or dialysis: start 2.5 mg. Max dose is 40 mg daily for most indications.

👨 Patient A — New Hypertension Diagnosis
CrCl: 85 | Age: 52 | Not on diuretic
Result: Start 10 mg once daily. Titrate to 20-40 mg based on BP response. Max 40 mg.
✅ "Standard starting dose. No renal adjustment needed."
👩 Patient B — Heart Failure with CKD
CrCl: 22 | Age: 74 | Hyponatremia (Na 128)
Result: Start 2.5 mg once daily (halved from 5 mg due to CrCl 10-30 + hyponatremia). Monitor renal function and K+ closely.
⚠️ "High risk of hypotension and hyperkalemia. Start low, go slow."
What is a Lisinopril Dosage Calculator and How Does It Work?
A lisinopril dosage calculator is a clinical tool that helps healthcare providers determine the appropriate starting dose, titration schedule, and maximum daily dose of lisinopril based on the indication and the patient's renal function. Our lisinopril dosage calculator 2026 uses FDA labeling to provide accurate dosing for hypertension, heart failure, acute myocardial infarction, and pediatric hypertension. The calculator also adjusts for renal impairment (CrCl), concomitant diuretic use, hyponatremia, and low systolic blood pressure.
How does the lisinopril dosing calculator work? Select the indication, enter creatinine clearance (CrCl), choose patient type, and check any special conditions (on diuretic, hyponatremia, low SBP). The lisinopril dose calculator instantly shows the recommended starting dose, titration schedule, CrCl-adjusted max dose, renal adjustment, and safety status.
Lisinopril Dosing by Indication (2026 FDA Labeling)
Hypertension (Adults): Initial dose is 10 mg once daily. Patients on diuretics should start at 5 mg once daily. Titrate up to 40 mg daily based on blood pressure response. Doses up to 80 mg have been used but do not appear to give greater effect [citation:1][citation:9].
Heart Failure: Start 5 mg once daily as adjunctive therapy. If hyponatremia (serum sodium <130 mEq/L), start 2.5 mg once daily. Increase as tolerated to a maximum of 40 mg once daily [citation:9].
Acute Myocardial Infarction: Give 5 mg orally within 24 hours of MI, followed by 5 mg after 24 hours, 10 mg after 48 hours, then 10 mg once daily for at least 6 weeks. If systolic BP is 100-120 mmHg during the first 3 days, start with 2.5 mg [citation:9].
Pediatric Hypertension (≥6 years, GFR >30): Start 0.07 mg/kg once daily (max 5 mg). Titrate up to a maximum of 0.61 mg/kg (max 40 mg) once daily. Not recommended for age <6 or GFR <30 [citation:1].
Renal Impairment Dose Adjustments
CrCl >30 mL/min: No dose adjustment required.
CrCl 10-30 mL/min: Reduce the initial dose to half of the usual recommended dose: hypertension 5 mg, heart failure 2.5 mg, acute MI 2.5 mg. Up-titrate as tolerated to a maximum of 40 mg daily [citation:9].
CrCl <10 mL/min or hemodialysis: Recommended initial dose is 2.5 mg once daily. Titrate carefully based on blood pressure response [citation:1][citation:9].
Safety Monitoring and Contraindications
Monitor: Renal function (creatinine, eGFR) and serum potassium within 1-2 weeks of initiation and after dose increases. Watch for symptomatic hypotension, especially in volume-depleted patients or those on diuretics.
Contraindicated: Pregnancy (fetal toxicity), history of angioedema with any ACE inhibitor, concomitant aliskiren in patients with diabetes, and concomitant sacubitril/valsartan (requires 36-hour washout).
Caution: Renal artery stenosis, volume depletion, hyponatremia, concurrent potassium-sparing diuretics or potassium supplements, and NSAID use (may reduce efficacy and increase renal risk).
❓ Frequently Asked Questions
What is the starting dose of lisinopril for hypertension?
Initial adult dose is 10 mg once daily. Patients on diuretics should start at 5 mg once daily. Titrate up to 40 mg daily based on blood pressure response. Use our lisinopril dosage calculator for CrCl-adjusted dosing.
How is lisinopril dosed in heart failure?
Start 5 mg once daily. If hyponatremia (Na <130 mEq/L), start 2.5 mg once daily. Increase as tolerated to max 40 mg once daily.
What is the lisinopril dose after a heart attack (MI)?

How is lisinopril adjusted for renal impairment?
CrCl >30: no adjustment. CrCl 10-30: halve usual initial dose (HTN: 5 mg; HF/MI: 2.5 mg). CrCl <10 or dialysis: start 2.5 mg once daily. Titrate to max 40 mg as tolerated.
What is the pediatric dose of lisinopril?
Children ≥6 years with GFR >30: start 0.07 mg/kg once daily (max 5 mg). Titrate to max 0.61 mg/kg (max 40 mg) once daily. Not recommended if GFR <30 or age <6.
When is lisinopril contraindicated?
Contraindicated in pregnancy, history of angioedema with ACE inhibitors, and concomitant aliskiren in patients with diabetes. Use with caution in renal artery stenosis and volume depletion.
💡 Expert Tips for Lisinopril Dosing
Tip #1: Always check renal function and potassium before starting lisinopril and within 1-2 weeks after initiation or dose changes.
Tip #2: In patients on diuretics, consider holding the diuretic for 2-3 days before starting lisinopril to reduce first-dose hypotension risk.
Tip #3: Start low and go slow in the elderly and in patients with CrCl 10-30. Halve the usual starting dose.
Tip #4: Avoid combining lisinopril with potassium supplements or potassium-sparing diuretics unless specifically indicated and monitored closely.
