How often should a senior monitor blood pressure at home, and what readings should prompt a call to the doctor?

For seniors managing hypertension, twice-daily readings — morning before medication, evening before bed — are recommended during medication adjustments; weekly readings suffice once stable. Report promptly: systolic consistently above 180, below 90, or any reading accompanied by headache, chest pain, or visual changes. White coat hypertension is common in seniors, and home monitoring is the recommended way to distinguish it from true hypertension.
