Fosinopril Dosage & Administration

Fosinopril dosing must be individualised to the patient's condition, weight, kidney and liver function, and other medications. Most ACE inhibitors are dosed once or twice daily. Start at low doses and titrate upward based on blood pressure response and tolerability. Take at the same time each day.

→Hypertension: start low, titrate over weeks to target BP
→Heart failure: start very low, titrate slowly to target dose
→Diabetic nephropathy: aim to maximise dose within tolerance
→Post-MI: start within 24 hours if stable

Dosage Safety Notes

→Check renal function and potassium before starting and after dose changes
→Hold dose if patient is dehydrated (e.g., vomiting, diarrhoea, before surgery)
→First dose may cause hypotension — consider first dose at bedtime

Frequently Asked Questions

Can I take a higher dose of Fosinopril if my symptoms don't improve?

No. Never increase the dose of Fosinopril without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.

Why does the ACE inhibitor cause a cough?

ACE inhibitors prevent the breakdown of bradykinin, which accumulates in the airways causing irritation and a dry, persistent cough. This affects 10–15% of patients. If troublesome, switching to an ARB typically resolves the cough.
