Should a patient with a blood pressure below 110/60 mm Hg hold their antihypertensive medication?

Should a Patient Hold Their BP Medication for BP <110/60?

No, a patient should not automatically hold their antihypertensive medication based solely on a single blood pressure reading of <110/60 mmHg. The decision requires assessment of symptoms, orthostatic vital signs, and the clinical context rather than an arbitrary numerical cutoff.

Clinical Approach to Low Blood Pressure on Antihypertensives

Assess for Symptomatic Hypotension First

The key distinction is whether the patient is experiencing symptoms of hypotension:

• Symptomatic hypotension (lightheadedness, dizziness, syncope, falls) warrants immediate evaluation and potential medication adjustment 1
• Asymptomatic chronic hypotension exists and does not necessarily require intervention 2

Screen for Orthostatic Hypotension

Before making medication changes, measure orthostatic vital signs 1. The 2025 AHA/ACC guidelines emphasize screening for orthostatic hypotension (OH) prior to intensification of antihypertensive treatment and monitoring during treatment, as OH affects 7-10% of community-dwelling adults with hypertension and is associated with adverse cardiovascular outcomes 1.

Consider Diastolic Blood Pressure Specifically

Diastolic BP ≤65 mmHg deserves particular attention:

• In nursing home residents, DBP ≤65 mmHg was independently associated with a 3-fold increased risk of hospitalization (OR=3.06,95% CI 1.02-9.15) after adjusting for multiple factors 3
• In patients with isolated systolic hypertension, systolic BP lowering may be limited if diastolic BP decreases below 60-65 mmHg 4

When to Consider Medication Adjustment

Hold or reduce medications if:

• Patient has symptomatic hypotension with lightheadedness or dizziness 4
• Orthostatic hypotension is documented 1
• Diastolic BP consistently ≤60-65 mmHg, especially in older adults 4, 3
• Patient is frail or aged ≥85 years with poor tolerance 5

Do NOT automatically hold if:

• Patient is asymptomatic with BP <110/60 mmHg 2
• This is a single isolated reading (confirm with repeated measurements)
• Patient has high cardiovascular risk requiring ongoing BP control 5

Important Caveats

The J-Curve Concern

While concerns exist about overtreatment increasing coronary risk, a consistent "J-curve" effect is not reliably demonstrated in clinical studies 6. However, clinical judgment remains essential.

Guideline Context

The 2024 ESC guidelines recommend targeting systolic BP 120-129 mmHg in most adults, with the "as low as reasonably achievable" (ALARA) principle when treatment is poorly tolerated 5. The 2025 AHA/ACC guidelines emphasize that concerns about worsening orthostatic hypotension have contributed to advice against intensive BP treatment in older adults 1.

Medication Continuation

It is recommended to maintain BP-lowering treatment lifelong, even beyond age 85 years, if well tolerated 5. The default should be continuation unless specific contraindications exist.

Practical Algorithm

1. Check for symptoms → If symptomatic, evaluate orthostatic vitals
2. Measure orthostatic BP → If positive OH, consider medication reduction
3. Assess diastolic BP → If consistently ≤60-65 mmHg, consider adjustment
4. Evaluate frailty/age → If frail or ≥85 years with poor tolerance, individualize
5. If asymptomatic with normal orthostatics → Continue medications and monitor

The numerical threshold of 110/60 mmHg alone should not trigger automatic medication discontinuation without clinical correlation.
