Starting & titration
- Check baseline potassium and kidney function; recheck 1–2 weeks after initiation or dose change.
- Typical once-daily dosing; split dosing optional for BP variability.
Safety
- Watch for dizziness, hyperkalemia, or rising creatinine. Small creatinine bumps can be expected; large increases require review.

Interactions
- Potassium-sparing diuretics/ACEIs/aldosterone antagonists raise hyperkalemia risk.
- NSAIDs can blunt BP control and worsen kidney function—use cautiously.
