From the Guidelines
The initial treatment for hypertensive urgency involves oral antihypertensive medications to gradually lower blood pressure over 24-48 hours, with the goal of reducing blood pressure by no more than 25% in the first few hours to avoid organ hypoperfusion. The choice of medication should be based on the patient's clinical presentation and comorbidities. According to the seventh report of the joint national committee on prevention, detection, evaluation, and treatment of high blood pressure 1, medications like labetalol, amlodipine, or captopril can be used to treat hypertensive urgency.
Key Considerations
- Start with medications like labetalol (200-400 mg orally), amlodipine (5-10 mg), or captopril (25 mg) to gradually lower blood pressure over 24-48 hours.
- Monitor the patient for 3-6 hours to ensure blood pressure is decreasing appropriately without complications.
- Evaluate patients for underlying causes of hypertension and end-organ damage through basic laboratory tests including complete blood count, electrolytes, creatinine, and urinalysis.
- Establish a long-term management plan with regular follow-up within 1-7 days, incorporating lifestyle modifications such as sodium restriction, weight loss, and physical activity alongside pharmacological treatment.
Important Notes
- Hypertensive urgency does not involve acute end-organ damage, so rapid, aggressive blood pressure reduction is unnecessary and potentially harmful 1.
- The standards of medical care for patients with diabetes mellitus also emphasize the importance of lifestyle and behavioral therapy in managing hypertension, in addition to pharmacological treatment 1.

From the Research
Hypertension Urgency Treatment
The initial treatment for a patient presenting with hypertension urgency is focused on gradually lowering the blood pressure over a period of 24-48 hours using oral medications.
- The goal is to avoid aggressive blood pressure lowering, which can be harmful 2.
- Oral medications such as nifedipine, captopril, clonidine, labetalol, prazosin, and nimodipine have been shown to be effective in managing hypertensive urgencies 3.
- The choice of medication depends on the underlying causes of the crisis, patient demographics, cardiovascular risk, and comorbidities 2.
- It is essential to individualize therapy and monitor the patient's response to treatment to minimize complications such as hypotension and ischemic brain damage 4.
Key Considerations
- Hypertensive urgencies are characterized by a severe elevation in blood pressure without evidence of new or worsening organ damage 2.
- The treatment approach differs from hypertensive emergencies, which require immediate treatment with intravenous antihypertensive medications 3, 5.
- Lifestyle modifications, such as weight loss, healthy dietary patterns, physical activity, and moderation of alcohol consumption, are also important in managing hypertension 6.
- First-line drug therapy for hypertension consists of thiazide or thiazide-like diuretics, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and calcium channel blockers 6.
