Overview
Hydralazine is a vasodilator and antihypertensive medication. It may be ordered for Blood Pressure management or as part of a provider-ordered cardiac plan depending on patient diagnosis, medication profile, discharge instructions, pharmacy label, and plan of care. Apresoline is a common brand name associated with hydralazine.
For home health nurses, Hydralazine indication and home health teaching often focuses on medication compliance, Blood Pressure management support when ordered, dizziness and orthostatic safety, fall prevention, headache awareness, pulse/Blood Pressure monitoring reminders if ordered, medication list review, reporting palpitations or chest pain, reporting worsening shortness of breath or swelling, avoiding independent medication changes, and knowing when to notify PCP or call 911.
DailyMed describes hydralazine hydrochloride as an antihypertensive and states that its major effects are cardiovascular, lowering Blood Pressure through a peripheral vasodilating effect and direct relaxation of vascular smooth muscle. DailyMed lists its indication as essential Hypertension, alone or as an adjunct. MedlinePlus states that hydralazine is used to treat high Blood Pressure, is in a class called vasodilators, and works by relaxing blood vessels so blood can flow more easily.
Hydralazine may help manage Blood Pressure as ordered, but it does not cure Hypertension or replace provider evaluation for worsening symptoms. Patient-specific use, precautions, monitoring, and administration instructions must always follow provider order, medication profile, pharmacy label, discharge instructions, plan of care, agency policy, and skilled nursing judgment.

Common Indications for Hydralazine
Common indications may include:
- Hypertension
- High Blood Pressure
- Blood Pressure control
- Provider-ordered antihypertensive therapy
- Provider-ordered vasodilator therapy

DailyMed lists hydralazine hydrochloride tablets for essential Hypertension, alone or as an adjunct. MedlinePlus notes that hydralazine is also used after heart valve replacement and in treatment of heart failure, and advises patients to talk with doctor about risks when used for those conditions.
Drug classification is not the same as patient-specific indication. For example, Hydralazine may be classified as a vasodilator or antihypertensive medication, but patient-specific indication may be Hypertension, Blood Pressure control, adjunct Blood Pressure therapy, provider-ordered vasodilator therapy, or heart failure support when specifically ordered.

Home Health Teaching Focus
For home health nursing, Hydralazine teaching often focuses on medication compliance, Blood Pressure monitoring if ordered, pulse monitoring if ordered, dizziness precautions, orthostatic safety, fall prevention, headache awareness, palpitations reporting, chest pain reporting, shortness of breath reporting, swelling reporting, medication list review, and when to notify PCP.
Patients may need reinforcement if they have a new Hydralazine order, recent Hospital stay, Hypertension, abnormal Blood Pressure readings, dizziness, weakness, fall risk, headache, palpitations, chest discomfort, heart failure history, swelling, shortness of breath, medication confusion, missed doses, refill problems, or PCG involvement.
Patient Teaching Points for Hydralazine
Basic teaching may include:
- Take Hydralazine exactly as ordered by PCP/provider and pharmacy label.
- Do not stop, hold, skip, take extra, or change medication unless instructed by PCP/provider.

- Report dizziness, lightheadedness, fainting, weakness, severe headache, palpitations, fast heartbeat, swelling, worsening shortness of breath, or symptoms that continue or worsen.
- Use fall precautions and rise slowly if dizzy, weak, or unsteady.
- Report chest pain, worsening shortness of breath, swelling, numbness/tingling, fever, joint or muscle pain, or symptoms that feel concerning.
- Do not adjust medication based on Blood Pressure readings unless PCP/provider gives specific instructions.
- Ask PCP or pharmacist before starting new over-the-counter medications, supplements, or interacting medications.
- Keep updated medication list available for PCP, pharmacy, home health agency, and Hospital visits.
