Neurogenic Orthostatic Hypotension: Treatments




STEP 1: Medication review Modify and/or discontinue drugs that can induce or exacerbate OH: • Dopaminergic agents • Antidepressants (esp. TCAs)* • Anticholinergics • Antihypertensives: diuretics, nitrates, alpha-1 blockers*, calcium channel blockers, hydralazine, minoxidil, beta-blockers, clonidine, alpha-methyldopa, ACEIs, ARBs • PDE5 inhibitors	2 week assessment ⇨	STEP 2: Non-pharmacologic measures Incorporate daily: • Blood volume repletion • Salt intake adjustment • Physical conditioning • Core body temperature regulation • Head of bed elevation • Compression garment use^† • Diet modification • B12 deficiency/anemia correction

		2 week assessment ⇩

STEP 4: Combination pharmacologic measures • Initiate a second agent if deemed necessary • Begin at lowest starting dose and titrate to maximum tolerated dose	⇦ 2 week assessment	STEP 3: Pharmacologic measures • Midodrine • Droxidopa • Fludrocortisone • Pyridostigmine

Drug	Indication Status	Usual Dose	Notes
Single-Agent Pharmacologic Treatments
Midodrine	FDA-approved	2.5–15mg once to three times daily while awake; titrate based on response	• Avoid within 5hrs of bedtime due to risk of supine hypertension • Caution in CHF, chronic renal failure
Droxidopa	FDA-approved	100–600mg three times daily while awake; titrate every 48hrs based on response and/or tolerability	• Avoid within 5hrs of bedtime due to risk of supine hypertension • Caution in CHF, chronic renal failure
Fludrocortisone	Off-label	0.1–0.2mg once daily; max 0.3mg/day	• Caution in CHF
Pyridostigmine	Off-label	30–60mg once to three times daily	• Beneficial in less severe patients • Does not worsen supine hypertension
NOTES
Key: ACEI = angiotensin converting enzyme inhibitor; ARB = angiotensin receptor blocker; CHF = congestive heart failure; nOH = neurogenic orthostatic hypotension; OH = orthostatic hypotension; PDE5 = phosphodiesterase E5; TCA = tricyclic antidepressant * Causes significant worsening of OH/nOH. ^†Waist-high compression garments are the most effective, followed by thigh-high compression stockings. Abdominal binders are effective alternatives, which can be used alone or in combination with leg compression if needed.
