High blood pressure online: when telehealth fits
Hypertension management via telehealth works when patients commit to reliable home blood pressure monitoring. The medications are well-studied, the dose adjustments are straightforward, and most patients don't need monthly in-person visits. The friction is the home cuff and the discipline to use it.

Home monitoring is essential
Validated upper-arm cuff (not wrist). Measure twice a day, two readings each, for at least one week. Average is the number that matters — not any single high reading. Programs that prescribe without home BP logs are flying blind.
First-line medications
Thiazide diuretics (hydrochlorothiazide, chlorthalidone), ACE inhibitors (lisinopril), ARBs (losartan), calcium channel blockers (amlodipine). All generic, $5-15/month. Selection depends on age, race, comorbidities (diabetes, kidney disease), and side-effect tolerance.
What telehealth handles
Initial diagnosis (with confirmed home BP), monotherapy initiation, dose titration, switching between first-line classes, second-agent addition. Bloodwork (kidney function, electrolytes) can be ordered to LabCorp/Quest.
When to escalate
Refractory hypertension on 3+ medications, secondary hypertension workup (renal artery stenosis, aldosteronism, etc.), pregnancy, kidney disease requiring nephrology, hypertensive urgency or emergency. In-person care needed.
