Apresoline (Hydralazine Hydrochloride)

Common Use

Apresoline contains the active ingredient hydralazine, which belongs to a class of medications called vasodilators—in simple terms, it works by relaxing and widening the blood vessels. When blood vessels are wider, blood can flow more easily, which helps lower blood pressure and reduces the workload on the heart.

Apresoline is used to treat:

High blood pressure (hypertension) – a condition where the force of blood against the artery walls is consistently too high, which can increase the risk of heart attack, stroke, and kidney problems

Heart failure – in some cases, Apresoline is used in combination with other medications (such as nitrates) to help improve symptoms and reduce the strain on the heart

Because Apresoline works well alongside other blood pressure medications, it is often prescribed as part of a combination therapy to achieve better blood pressure control than a single medication alone.

Dosage and Direction

Take Apresoline exactly as prescribed by your doctor. The typical dose ranges from 10 mg to 50 mg, taken up to four times daily. Swallow the tablets with water and follow your doctor’s schedule for the best results.

Your doctor will usually start you on a lower dose and gradually increase it to find the dose that works best for you while minimizing side effects. Do not change your dose or stop taking the medication without consulting your doctor, as this can cause your blood pressure to rise suddenly.

Precautions

Monitor your blood pressure regularly while using this medicine, as directed by your doctor. Keeping a record can help your doctor adjust your treatment as needed

Inform your doctor if you have:

Heart disease (such as coronary artery disease or heart valve problems)

Kidney problems

Lupus (systemic lupus erythematosus) – hydralazine can, in rare cases, trigger or worsen lupus-like symptoms

Liver problems

Apresoline can sometimes cause fluid retention (swelling in the ankles or feet). If you notice this, let your doctor know

Contraindications

Apresoline should not be used in the following situations:

Allergy – if you are allergic to hydralazine or any of the ingredients in the medication

Severe coronary artery disease – because hydralazine can increase the workload on the heart in certain situations

Certain heart valve problems – such as rheumatic heart disease affecting the mitral valve

Possible Side Effects

Common side effects may include:

Headache

Dizziness

Nausea

Rapid heartbeat (tachycardia) – this is a common response as the body adjusts to lower blood pressure

Palpitations (feeling like your heart is racing or skipping a beat)

Less common but more serious side effects (rare) may include:

Lupus-like syndrome – symptoms may include joint pain, skin rash, fever, and fatigue. This is usually reversible when the medication is stopped

Swelling (fluid retention) – which can be a sign of heart failure worsening

Liver problems – symptoms may include yellowing of the skin or eyes (jaundice), dark urine, or abdominal pain

If you experience any of these more serious symptoms, contact your doctor immediately.

Drug Interactions

Apresoline may interact with other medications:

Other blood pressure medicines – Apresoline can increase their effects, which may cause blood pressure to drop too low. Your doctor will monitor this

Beta-blockers (such as propranolol, metoprolol) – are often prescribed together with Apresoline to help prevent the rapid heartbeat that hydralazine can sometimes cause

Diuretics (water pills) – may be used together with Apresoline to help prevent fluid retention

Always inform your doctor about all medications you are taking, including over-the-counter products and herbal supplements.

Missed Dose

If you miss a dose, take it as soon as you remember—unless it is almost time for your next dose. If that’s the case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for a missed one.

Overdose

An overdose of Apresoline can cause:

Severe low blood pressure (hypotension)

Fast heartbeat

Fainting

Weakness or dizziness

If you suspect an overdose, seek emergency medical attention immediately.

Storage

Store Apresoline at room temperature, away from moisture, heat, and direct light. Keep it out of reach of children.
