Alfuzosin is primarily indicated for the treatment of benign prostatic hyperplasia (BPH), a common condition in aging men characterized by enlargement of the prostate gland. By relaxing the smooth muscles in the prostate and bladder neck, alfuzosin improves urinary symptoms associated with BPH, such as urinary hesitancy, weak stream, incomplete bladder emptying, and nocturia.

Alfuzosin may also be prescribed to alleviate urinary retention, a condition where the bladder does not empty completely, often occurring as a complication of BPH. By relaxing the muscles in the bladder neck and urethra, alfuzosin helps improve bladder emptying and reduce the risk of urinary tract infections and other complications associated with urinary retention.

In some cases, healthcare providers may prescribe alfuzosin for off-label uses, such as the management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Although not approved by regulatory agencies for this indication, alfuzosin may be used off-label based on clinical judgment and evidence supporting its efficacy in relieving symptoms of pelvic pain and urinary dysfunction associated with CP/CPPS.

Alfuzosin works by selectively blocking alpha-1 adrenergic receptors in the smooth muscle of the prostate gland, bladder neck, and urethra. By doing so, it prevents the action of norepinephrine, a neurotransmitter that causes smooth muscle contraction.

This blockade leads to relaxation of the smooth muscle in the prostate and bladder neck, reducing constriction of the urethra and improving urine flow. Additionally, alfuzosin helps alleviate symptoms of BPH by decreasing pressure on the urethra, thereby relieving urinary hesitancy, urgency, and frequency.

Common side effects:

• Dizziness: Dizziness is a common side effect of alfuzosin, especially when rising from a sitting or lying position. Patients should avoid activities requiring mental alertness until they know how alfuzosin affects them.
• Headache: Headaches are reported by some individuals taking alfuzosin but often diminish with continued use.
• Fatigue: Feeling tired or fatigued is another common side effect that may occur during alfuzosin treatment.
• Stomach Discomfort: Mild stomach discomfort, including nausea or abdominal pain, may occur in some patients but is usually temporary.
• Orthostatic Hypotension: Alfuzosin can cause a sudden drop in blood pressure upon standing, known as orthostatic hypotension, leading to feelings of lightheadedness or fainting. 

These side effects are usually mild and transient, but patients experiencing persistent or severe symptoms should contact their healthcare provider.

Alfuzosin can cause orthostatic hypotension, a sudden drop in blood pressure upon standing, especially during the initial dose or dose escalation. Patients should rise slowly from a seated or lying position to minimize the risk of dizziness or fainting.

Use alfuzosin with caution in individuals with liver or kidney impairment, as dosage adjustments may be necessary due to altered drug metabolism or elimination. Close monitoring of liver and kidney function is recommended during treatment.

Patients scheduled for cataract surgery should inform their ophthalmologist if they are taking or have recently taken alfuzosin, as the medication can cause intraoperative floppy iris syndrome (IFIS), a complication during cataract surgery. Ophthalmologists may need to take special precautions during the procedure.

Rare cases of priapism (prolonged erection) have been reported with alfuzosin use. Patients experiencing an erection lasting longer than 4 hours should seek immediate medical attention to prevent potential complications.

Concomitant use of strong CYP3A4 inhibitors, such as ketoconazole, ritonavir, and clarithromycin, with alfuzosin may increase alfuzosin plasma concentrations. This can lead to an increased risk of hypotension and adverse effects. 

Concurrent use of alfuzosin with other alpha blockers, such as doxazosin or tamsulosin, may potentiate the hypotensive effects of both medications. Close monitoring of blood pressure is advised when using alfuzosin with other alpha blockers.

Combining alfuzosin with other antihypertensive drugs, such as beta blockers or calcium channel blockers, may enhance the blood pressure-lowering effects, increasing the risk of hypotension. Adjustments to the dosages of antihypertensive medications may be necessary when used concomitantly with alfuzosin.

Concomitant use of phosphodiesterase-5 (PDE5) inhibitors, such as sildenafil or tadalafil, with alfuzosin may potentiate the hypotensive effects, leading to symptomatic hypotension. Patients should be monitored closely for signs and symptoms of low blood pressure when these medications are used together.

The recommended starting dose of alfuzosin is 10 mg orally once daily, taken after a meal. If necessary, the dosage may be increased to 10 mg twice daily, based on individual response and tolerability. The second dose should also be taken after a meal.Swallow the tablets whole; do not crush or chew.

Alfuzosin tablets should be swallowed whole and not crushed or chewed.For patients with mild to moderate hepatic impairment, the recommended starting dose is 10 mg once daily. However, alfuzosin should be used with caution in this population, and dosage adjustments may be necessary. Blood pressure should be assessed regularly during treatment, particularly in patients at higher risk of hypotension.

• Alfuzosin is available only with a prescription from a healthcare provider.
• It is classified as a prescription medication due to its potential side effects and interactions with other drugs.
• Patients cannot obtain alfuzosin over the counter; they must consult a healthcare professional for evaluation and prescription.
• A healthcare provider will assess the patient’s medical history, current medications, and overall health status before prescribing alfuzosin.
• Prescription requirement ensures that patients receive appropriate guidance on dosage, administration, potential side effects, and precautions associated with alfuzosin use.
• Healthcare providers monitor patients’ response to treatment and adjust the dosage as necessary to optimize therapeutic outcomes and minimize adverse effects.
• Patients should adhere to their healthcare provider’s instructions and attend follow-up appointments for monitoring and assessment of treatment efficacy and safety.
