Uroxatral (Alfuzosin) – Patient Information (UK)

Uroxatral contains alfuzosin, a medicine used to treat symptoms caused by a enlarged prostate (benign prostatic hyperplasia, BPH). It helps improve urine flow and reduces troublesome lower urinary tract symptoms such as difficulty starting urination, weak stream, frequent urination, or needing to urinate urgently, especially at night.

This page explains how Uroxatral works, how it’s usually taken, key safety information, food and medicine interactions, and practical tips to make treatment easier. Always follow the instructions provided with your medicine.

Quick facts

• Active ingredient: Alfuzosin
• Common purpose: Relieves urinary symptoms due to enlarged prostate
• Medicine type: Alpha-1 adrenergic blocker (alpha-blocker)
• Typical dosing form: Extended-release tablet(s)
• Main benefit: Improves urine flow and reduces symptoms

What is Uroxatral?

Uroxatral is an extended-release alpha-blocker used in adults to treat lower urinary tract symptoms related to benign prostatic hyperplasia (BPH). In BPH, the prostate gland becomes larger over time, which may narrow the urethra and make urination difficult.

Uroxatral does not shrink the prostate directly. Instead, it relaxes the smooth muscle in the prostate and bladder neck, which can make it easier to pass urine.

How Uroxatral works (mechanism of action)

Alfuzosin blocks alpha-1 adrenergic receptors found in smooth muscle, including in:

• Prostate tissue
• Bladder neck
• Proximal urethra

By relaxing these tissues, Uroxatral reduces resistance to urine flow. This leads to:

• Improved urine stream
• Reduced difficulty starting urination
• Less straining and incomplete emptying sensations
• Lower urgency and frequency in many people

Pharmacokinetics (how the body handles the medicine)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated. Uroxatral is designed as an extended-release formulation to help maintain steadier blood levels over time.

• Absorption: Alfuzosin is absorbed after ingestion; taking it correctly with food helps achieve reliable levels.
• Onset: Some symptom improvement may be noticed within days, but the full benefit can take longer.
• Metabolism: The medicine is metabolised mainly in the liver.
• Elimination: Metabolites are eliminated primarily through the body’s normal clearance pathways.

Your individual response may vary, particularly depending on the severity of BPH symptoms and any other medical conditions.

Typical use in the UK

Uroxatral is used to treat symptoms of BPH in men. It is commonly used when urinary symptoms are bothersome and affect quality of life, such as:

• Weak urinary stream
• Difficulty starting urination
• Intermittent flow
• Dribbling after finishing
• Frequent urination, including at night (nocturia)
• Urgency to urinate

If you are experiencing urinary retention (being unable to pass urine at all) or severe symptoms, seek urgent medical advice.

Indications (what conditions it’s used for)

Uroxatral is indicated for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia.

How to take Uroxatral: timing and instructions

Correct timing can significantly affect how well alfuzosin works and how safely it is tolerated. Many extended-release alpha-blockers require consistent use with meals.

Typical dosing schedule

The most common adult dosing regimen is:

• Once daily, in the evening or at the same time each day (as directed by your clinician and the product label).

Important: Follow the instructions on your specific pack. Dosing may vary depending on the formulation strength and your health status (for example, kidney or liver function).

Take with food (food timing matters)

Uroxatral is generally taken after the same meal each day to improve absorption and reduce variability. Taking it without food may increase side effects in some people or reduce effectiveness.

Swallow whole

• Swallow the tablet whole with water.
• Do not crush or chew (this may alter extended-release properties).

Missing a dose

• If you miss a dose, take it as soon as you remember if it is close to your usual time and you have not taken the next dose.
• If it is nearly time for your next dose, skip the missed dose.
• Do not take a double dose to make up for the missed one.

Food interactions

Food is an important factor for alfuzosin absorption. In practice, the key point is: take Uroxatral with food (typically after a meal) as directed on your pack.

• Recommended: Take after a meal or as specified in the patient information leaflet.
• Avoid: Taking on an empty stomach unless the label explicitly allows it.

If you have questions about your meal timing (for example, shift work, irregular eating, or reduced appetite), speak with a pharmacist for personalised guidance.

Alcohol and medicine interactions

Alcohol

Alcohol can increase the likelihood of side effects such as dizziness or light-headedness, particularly when starting or increasing the dose of an alpha-blocker. To reduce risk:

• Consider limiting alcohol.
• Avoid alcohol if you notice dizziness after taking your dose.
• Be cautious with driving or operating machinery.

Other medicines that may interact

Alfuzosin can interact with drugs that affect blood pressure or are also metabolised through liver pathways. Tell your pharmacist or clinician about all medicines you take, including those bought without a prescription.

Common interaction areas include:

• Other alpha-blockers (may increase risk of low blood pressure)
• Medicines for erectile dysfunction such as sildenafil, tadalafil, or vardenafil (can increase risk of symptomatic low blood pressure when combined)
• Blood pressure medicines (the effect on blood pressure may add up)
• Nitrates (used for chest pain/angina) and other vasodilators (may increase risk of low blood pressure)
• Certain antibiotics and antifungal medicines that can inhibit metabolism (may increase alfuzosin levels)
• Strong CYP3A4 inhibitors (metabolic pathway involved in processing alfuzosin)

For safety, it is particularly important to check for interactions if you are taking heart medicines, erectile dysfunction medicines, strong antifungals, or certain antibiotics.

Dosing information (what you need to know)

Never change the dose or stop treatment suddenly without advice, especially if you have significant urinary symptoms.

Safety profile: side effects and when to seek help

Common side effects

Like all medicines, Uroxatral can cause side effects. Many are mild and improve as your body adjusts. Possible side effects include:

• Dizziness or light-headedness
• Headache
• Fatigue
• Low blood pressure symptoms (especially when standing)
• Stomach discomfort or nausea
• Swelling (less common)

Less common but important effects

• Fainting or near-fainting
• Palpitations (feeling of abnormal heartbeats)
• Allergic reactions (rash, itching, swelling, breathing difficulty)
• Priapism (a painful prolonged erection)—seek urgent medical attention

When to get urgent medical help

Seek urgent help (NHS 111 or emergency services depending on severity) if you experience:

• Fainting or severe dizziness
• Severe allergic reaction signs (swelling of face/lips, difficulty breathing)
• Chest pain, severe palpitations, or collapse
• Sudden inability to urinate
• Priapism (prolonged painful erection)

Driving and operating machinery

Because alfuzosin can cause dizziness or changes in blood pressure, take care when:

• Starting treatment
• Restarting after a break
• Changing dose

If you feel dizzy, do not drive or use machinery until you feel normal again.

Practical use tips (making treatment easier)

• Take it after food as directed—this can improve consistency of effect.
• Be careful when standing up especially during the first few days: move slowly from sitting/lying to standing.
• Know your triggers: if you drink alcohol or take other blood-pressure-lowering medicines, dizziness risk may increase.
• Track symptoms (e.g., time to start urinating, stream strength, night-time trips) to assess progress over weeks.
• Hydration matters: drink enough fluids for your lifestyle, but avoid large amounts late in the evening if nocturia is a problem.
• Don’t ignore warning signs: severe pain, fever, or sudden inability to urinate needs urgent assessment.

Alternative options for BPH symptoms (what else may be used)

Treatment options for BPH depend on symptom severity, prostate size, and individual risk factors. Alternatives include:

Other medication types

• Other alpha-blockers (different dosing schedules and side-effect profiles)
• 5-alpha-reductase inhibitors (e.g., finasteride, dutasteride) which may help shrink the prostate over time
• Combination therapy in selected patients (often when prostate is larger and symptoms are significant)

Non-medicine options

• Behavioural strategies (timed voiding, reducing late evening fluids)
• Minimally invasive procedures or surgery when medicines are insufficient or complications occur

Ask a pharmacist or clinician which option is most suitable for you. The best choice depends on your prostate size, symptom pattern, and overall health.
