From the Guidelines
Hypertensive urgency requires prompt but not immediate treatment to lower blood pressure safely over 24-48 hours. For patients with hypertensive urgency, start with oral antihypertensive medications rather than IV agents. Good first-line options include labetalol 200-400mg orally, amlodipine 5-10mg, or captopril 25mg 1. Monitor blood pressure every 30-60 minutes initially, with a goal of reducing it by no more than 25% in the first 24 hours to avoid organ hypoperfusion. After initial control, establish a long-term medication regimen typically including a combination of drugs like an ACE inhibitor or ARB plus a calcium channel blocker or thiazide diuretic. Patients should follow up within one week. Unlike hypertensive emergency, urgency doesn't involve acute end-organ damage, but still requires attention to prevent progression. Common symptoms include severe headache, shortness of breath, or nosebleeds. Identify and address contributing factors such as medication non-adherence, pain, anxiety, or substances like cocaine or amphetamines. Patient education about medication adherence, sodium restriction, and lifestyle modifications is essential for long-term management.
Key Considerations
- Hypertensive urgency is characterized by severe BP elevation in otherwise stable patients without acute or impending change in target organ damage or dysfunction 1.
- Oral antihypertensive medications are preferred over IV agents for initial treatment 1.
- The goal is to reduce blood pressure by no more than 25% in the first 24 hours to avoid organ hypoperfusion 1.
- Long-term management involves establishing a medication regimen and addressing contributing factors such as medication non-adherence and lifestyle modifications 1.
Treatment Options
- Labetalol 200-400mg orally
- Amlodipine 5-10mg
- Captopril 25mg
- ACE inhibitor or ARB plus a calcium channel blocker or thiazide diuretic for long-term management 1.

From the Research
Definition and Classification of Hypertensive Urgency
- Hypertensive urgency is characterized by an acute and critical increase in blood pressure without signs or symptoms of acute hypertensive target organ damage 2.
- It is differentiated from hypertensive emergency, which is defined by the presence of acute hypertensive target organ damage, such as stroke, myocardial infarction, or heart failure 2, 3.
Treatment of Hypertensive Urgency
- Oral antihypertensive therapy is usually sufficient for the treatment of hypertensive urgency, with the goal of lowering blood pressure within 24 to 48 hours 2, 3.
- Various oral antihypertensive agents, including clonidine, nifedipine, captopril, and labetalol, have been shown to be effective in lowering blood pressure in patients with hypertensive urgency 4, 5, 6.
- The choice of agent should be based on the perceived need for urgent blood pressure control, the cause of the hypertensive urgency, and concomitant conditions 5.
Key Considerations in the Management of Hypertensive Urgency
- Immediate outpatient follow-up within 24 hours is mandatory in all patients who are not hospitalized to adjust the dose of antihypertensive medications 4.
- Hospitalization is not typically required for patients with hypertensive urgency, but further and continuing outpatient care must be ensured 2.
- The management of hypertensive urgency differs from that of hypertensive emergency, which requires immediate treatment with intravenous antihypertensive medications 3.
