Clinical information

Typical dosing

Dose depends on indication — do not use one number for all patients: • Hypertension: typical starting dose 10 mg once daily; usual maintenance 20–40 mg once daily. • Heart failure: start LOW — 2.5–5 mg once daily — then titrate upward as tolerated (target doses used in clinical trials were 20–40 mg/day). Starting HF patients at 10 mg risks symptomatic low blood pressure. • Post-heart-attack: started at low dose (2.5–5 mg) within 24 hours as tolerated, per prescriber.

Side effects

Common: dry cough, dizziness, headache. Serious (rare): swelling of face/lips/throat (angioedema), high potassium, kidney problems, symptomatic hypotension (especially after the first dose in heart-failure or volume-depleted patients).

Interactions to know

Avoid potassium supplements and salt substitutes containing potassium unless your doctor says otherwise. NSAIDs can reduce its effect and worsen kidney function.

Pregnancy & breastfeeding

Do not use during pregnancy — can cause fetal harm, especially in the 2nd/3rd trimester.
