Management of Dizziness in Elderly Hypertensive Patients

Assessment of Orthostatic Hypotension

Measure blood pressure in both supine and standing positions to detect orthostatic hypotension, which is the most common cause of dizziness in elderly patients with hypertension and is often aggravated rather than caused by elevated BP. 1
Include an erect‑posture BP measurement in addition to seated readings because older hypertensive adults have a higher risk of postural hypotension. 2

Central α‑2 agonists (e.g., clonidine, tizanidine) are especially likely to provoke dizziness in older adults and should be reviewed for dose reduction or discontinuation. (American Geriatrics Society) 5
For isolated systolic hypertension in the elderly, thiazide‑type diuretics and calcium‑channel blockers are recommended as first‑line agents. (European Society of Cardiology) 3
Angiotensin‑converting‑enzyme inhibitors or angiotensin‑receptor blockers are appropriate alternative antihypertensives in this population. (European Society of Cardiology) 4
Beta‑blockers should be avoided or used only minimally as first‑line therapy in patients > 60 years, because they provide less stroke‑prevention benefit and can worsen orthostatic symptoms. (Canadian Cardiovascular Society) 6
Initiate antihypertensive therapy at low doses and titrate slowly to mitigate adverse effects that are more common in frail older adults. (European Society of Cardiology) 1

A standard target of < 140/90 mm Hg is appropriate for most older adults. (International Society of Hypertension) 7
Guidelines explicitly advise individualizing targets based on frailty status; frail elders may require higher thresholds. (International Society of Hypertension) 8
Community‑dwelling, non‑frail seniors can safely aim for < 130/80 mm Hg when tolerated. (American Heart Association / Hypertension) 9
Patients > 80 years or those who are markedly frail should be managed with monotherapy and less aggressive BP goals. (International Society of Hypertension) 7
The SPRINT trial excluded participants with a standing systolic BP < 110 mm Hg, underscoring that aggressive lowering is not appropriate for those with orthostatic hypotension. (American Heart Association) 10

The above recommendations are derived from Class I/Level A evidence in the ESC/ESH hypertension guidelines (2007) and reinforced by later ISH statements (2020) and Canadian cardiology guidance (2011).
The association between central α‑2 agonists and dizziness in the elderly is supported by moderate‑quality observational data from the Journal of the American Geriatrics Society (2018).
