HelloPharmacist Editorial Team Bottom Line
Labetalol is a dual-action blood pressure medicine that lowers high blood pressure by relaxing blood vessels and calming the heart. The tablet form is for ongoing management of hypertension, while the intravenous injection is reserved for severe hypertension in a hospital. Never stop labetalol suddenly, watch for signs of liver problems, and keep all follow-up appointments so your doctor can monitor your response.

📖 Labetalol: Patient Information Guide

A plain-language walkthrough of Labetalol — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for▾

Labetalol is approved to lower blood pressure across several products and forms:

  • Labetalol HCL and Labetalol Hydrochloride tablets (oral) are indicated for the management of hypertension (high blood pressure) — used alone or in combination with diuretics
  • LABETALOL HCl, Labetalol HCl in Dextrose, Labetalol HCl in Sodium Chloride, and Labetalol Hydrochloride injections (intravenous) are indicated specifically for severe hypertension requiring rapid control in a hospital setting
  • Lowering blood pressure with labetalol reduces the risk of serious cardiovascular events, primarily stroke and heart attack
⚙️How it works▾

Labetalol blocks two sets of receptors simultaneously: alpha-1 receptors and beta receptors. Blocking alpha-1 receptors causes blood vessels to relax and widen, reducing the resistance the heart pumps against. Blocking beta receptors slightly slows the heart rate and reduces how hard the heart pumps. Together, these effects lower blood pressure without causing the reflex speeding of the heart that can happen with some other blood pressure medicines.

Because it blocks alpha-1 receptors, labetalol lowers blood pressure more when you are standing than when lying down. This means lightheadedness on standing can occur, particularly shortly after a dose change. The balance of alpha to beta blockade differs between the oral and intravenous routes, so the two forms have somewhat different hemodynamic profiles.

💊How it's taken▾

Labetalol is available as an oral tablet and as an intravenous injection — these two forms are used in very different situations and are not interchangeable.

  • Tablets (Labetalol HCL, Labetalol Hydrochloride): Taken by mouth, generally twice daily. Taking them with food increases absorption. Your doctor will start at a low dose and adjust gradually based on your blood pressure readings.
  • Injection (LABETALOL HCl, Labetalol HCl in Dextrose, Labetalol HCl in Sodium Chloride, Labetalol Hydrochloride): Given only intravenously in a hospital by healthcare professionals, either as repeated injections or a slow continuous infusion, with blood pressure monitored throughout.

Always follow your prescriber's specific instructions. Never adjust your dose or stop taking labetalol on your own.

🤒Side effects — in detail▾

Most side effects of labetalol are mild and tend to appear early in treatment. Common ones include:

  • Dizziness or lightheadedness, especially when standing up quickly
  • Fatigue or general tiredness
  • Nausea
  • Headache
  • Weakness
  • Vomiting
  • Tingling of the scalp or skin

Serious reactions — including liver injury (jaundice, dark urine, persistent appetite loss), signs of heart failure (worsening breathlessness), sudden severe low blood pressure, or severe low blood sugar — require prompt medical attention. Do not wait to contact your doctor if these occur.

⚠️Warnings & precautions▾
  • Liver damage: Labetalol can rarely cause serious liver injury, including liver failure and death. Watch for yellowing skin or eyes, dark urine, loss of appetite, right-sided abdominal pain, or flu-like symptoms. If these appear, stop labetalol and seek medical care immediately.
  • Do not stop suddenly: Abruptly stopping labetalol — especially with coronary artery disease — can trigger severe chest pain or heart attack. Always taper under medical supervision.
  • Heart failure: Labetalol can worsen heart failure in some patients. Report any new or worsening shortness of breath or swelling to your doctor.
  • Breathing problems: Labetalol should generally not be used in people with asthma or obstructive airway disease, as it can cause bronchospasm (airway tightening).
  • Diabetes: Labetalol can mask a fast heartbeat — one of the early warning signs of low blood sugar (hypoglycemia). Monitor blood sugar carefully and seek emergency help for severe hypoglycemia.
  • Postural hypotension: Blood pressure drops more when standing than lying down; lightheadedness or fainting can occur, especially 2–4 hours after a dose.
  • Surgery: Inform your anesthesiologist that you take labetalol — a dangerous interaction with certain anesthetics (notably halothane) can cause excessive blood pressure drops.
🔀What it interacts with▾

Several medicines and substances can interact with labetalol in clinically important ways:

  • Tricyclic antidepressants (e.g., amitriptyline) — may increase the risk of tremor when combined with labetalol
  • Cimetidine (heartburn medicine) — raises labetalol blood levels; dose adjustments may be needed
  • Halothane anesthesia — can cause an extreme drop in blood pressure when used with intravenous labetalol; your surgical team must be informed
  • Nitroglycerin — labetalol can amplify the blood pressure-lowering effect; extra monitoring is needed in patients with angina
  • Verapamil-type calcium channel blockers — additive effects on heart rate and blood pressure; use with caution
  • Digitalis glycosides (e.g., digoxin) — both slow heart conduction; combining them raises the risk of bradycardia (dangerously slow heart rate)
  • Beta-agonist bronchodilators (e.g., albuterol) — labetalol can reduce their effectiveness in people with breathing problems
  • Epinephrine (used for severe allergic reactions) — may be less effective in people on labetalol who have a history of severe allergic reactions

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it▾
  • Do not take labetalol if you have bronchial asthma or a history of obstructive airway disease — this is a strict contraindication
  • Do not take it if you have overt heart failure, cardiogenic shock, severe bradycardia, or greater-than-first-degree heart block
  • Tell your doctor if you have liver disease — labetalol can cause liver injury, and liver problems increase drug exposure in your body
  • Tell your doctor if you have diabetes — labetalol can hide early signs of low blood sugar
  • Tell your doctor if you have coronary artery disease — stopping labetalol suddenly is dangerous
  • Tell your doctor if you have a pheochromocytoma (a type of adrenal tumor) — labetalol can occasionally cause a paradoxical rise in blood pressure in these patients
  • Pregnancy: Labetalol crosses the placenta and has been associated with low blood pressure, slow heart rate, and low blood sugar in newborns. Use only if your doctor determines the benefit outweighs the risk.
  • Breastfeeding: Small amounts pass into breast milk; discuss the risk-benefit with your doctor
  • Children: Safety and effectiveness have not been established in pediatric patients
  • Older adults (60+): More likely to experience dizziness and lightheadedness when standing; take extra precautions to prevent falls
🚑If you take too much▾

Too much labetalol can cause a severe drop in blood pressure (especially when standing) and sometimes a dangerously slow heart rate. If an overdose is suspected, seek emergency medical care immediately — lie flat with legs elevated to help maintain blood flow to the brain. Dialysis does not effectively remove labetalol from the body, so hospital-based supportive treatment is essential.

📡Pharmacodynamics — effects in the body▾

Labetalol lowers blood pressure by simultaneously relaxing blood vessels (via alpha-1 blockade) and reducing the heart's workload (via beta blockade), producing a dose-related fall in blood pressure without a compensatory increase in heart rate. It also blunts the blood pressure and heart rate spikes caused by exercise. Blood pressure is lowered more when standing than when lying down because of the alpha-blocking effect, which can lead to lightheadedness on standing — most likely 2 to 4 hours after a dose.

🔬Pharmacokinetics — how your body processes it▾

After an oral dose, labetalol is fully absorbed from the gut, with peak blood levels reached within 1 to 2 hours. However, only about 25% of an oral dose reaches the bloodstream because of extensive first-pass metabolism in the liver — and taking it with food increases that amount. The drug has a half-life of about 6 to 8 hours after oral dosing, and steady blood levels are typically reached by the third day of regular dosing.

Labetalol is broken down mainly in the liver and excreted primarily through the urine. Liver impairment increases drug exposure. Neither hemodialysis nor peritoneal dialysis removes meaningful amounts of labetalol from the body. In older adults, elimination may be slower, generally meaning lower maintenance doses are needed.

📦How to store it▾

stored at 20° to 25°C (68° to 77°F) . Dispense in a tight, light-resistant container as defined in the USP, with a child-resistant closure (as required).

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Labetalol — the kind of thing our pharmacy team would talk through with you at the counter.

What exactly is labetalol used for? ▾
Labetalol is used to lower high blood pressure (hypertension). The tablet form is for ongoing daily management of hypertension, and can be used on its own or with other blood pressure medicines like diuretics. The intravenous injection form is used in hospitals specifically for severe hypertension that needs to be brought down quickly. By controlling blood pressure, labetalol helps reduce your risk of stroke and heart attack over time.
Is it okay to stop taking labetalol if I feel fine? ▾
Please don't stop labetalol on your own, even if you feel great — this is really important. Stopping suddenly, especially if you have coronary artery disease (even undiagnosed), can trigger serious chest pain or even a heart attack. If you and your doctor decide it's time to stop, the dose should be reduced gradually over one to two weeks with close monitoring. Always talk to your prescriber before making any changes.
I feel dizzy when I stand up after taking labetalol — is that normal? ▾
Yes, this is a known effect. Labetalol lowers blood pressure more when you're standing than lying down, which can cause lightheadedness when you get up quickly — especially 2 to 4 hours after a dose. It's usually more noticeable early in treatment or after a dose increase. Standing up slowly, sitting on the edge of the bed for a moment first, and staying well hydrated can help. If you actually faint or the dizziness is severe, let your doctor know right away.
What side effects should I actually watch out for? ▾
Most people find labetalol quite tolerable — fatigue, mild nausea, dizziness, and headache are the most common complaints, and they often ease up after the first few weeks. The side effect that really warrants a call to your doctor is any sign of liver trouble: yellowing of your skin or eyes, dark urine, persistent loss of appetite, or flu-like symptoms that don't go away. Also call right away if you notice worsening shortness of breath, chest pain, or if you have diabetes and experience severe low blood sugar.
Can I take labetalol if I'm pregnant or breastfeeding? ▾
Labetalol does cross the placenta, and babies born to mothers who took it have sometimes had low blood pressure, a slow heart rate, or low blood sugar at birth. That said, untreated high blood pressure in pregnancy carries its own serious risks, so your doctor may still prescribe it if the benefit outweighs the risk — this is a conversation to have openly with your healthcare team. If you're breastfeeding, very small amounts pass into breast milk, so again, discuss it with your doctor so you can make the best decision for you and your baby.
Are there medicines I should avoid while taking labetalol? ▾
A few interactions are worth knowing about. Cimetidine — a common over-the-counter heartburn medicine — can raise labetalol levels in your blood, so let your doctor know if you use it regularly. If you take digoxin or verapamil for your heart, combining them with labetalol can slow your heart rate more than intended. If you use a rescue inhaler (like albuterol) for asthma or COPD, labetalol can reduce how well it works. And if you're having surgery, be sure to tell your anesthesiologist you're on labetalol — it can interact with certain anesthetics and cause a large blood pressure drop.
Is Labetalol available over the counter? ▾
Labetalol is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Labetalol first available? ▾
Labetalol has been available in the United States since at least 1984, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Labetalol? ▾
Labetalol is supplied by 68 manufacturers listed in the FDA NDC Directory, including Bryant Ranch Prepack, A-S Medication Solutions, Remedyrepack Inc..

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 70 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Marlex Pharmaceuticals Inc is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
