Uroxatral (Generic Alfuzosin): Complete Medication Guide
Key Takeaways
Alfuzosin is a prescription medication that relaxes muscles in the prostate and bladder to ease urinary symptoms related to benign prostate enlargement.
The generic version works the same way as brand-name Uroxatral but typically costs much less.
Common side effects include dizziness, fatigue, and headache, which may improve over time.
It's important to take alfuzosin exactly as prescribed and discuss any concerns with your healthcare provider.
This medication is for men only and may take several weeks to show full benefits.
Uroxatral (Generic Alfuzosin) Overview
Alfuzosin is a prescription medication belonging to a class of drugs called alpha-blockers. It's used to treat symptoms of benign prostate hyperplasia (BPH), which is an enlarged prostate gland common in older men. When the prostate grows larger, it can squeeze the urethra—the tube that carries urine out of the body—causing urinary problems like difficulty starting urination, weak urine flow, and needing to urinate frequently, especially at night.
Alfuzosin works by relaxing the smooth muscles in the prostate and bladder neck, making it easier for urine to flow. This helps reduce bothersome urinary symptoms without actually shrinking the prostate. The generic version contains the same active ingredient as brand-name Uroxatral and has the same effectiveness. Generic vs Brand Name Drugs explains how generic medications provide the same medical benefit at a lower cost. Many men find relief from their urinary symptoms within a few weeks of starting treatment, though it may take longer for full results.

Side Effects
Alfuzosin is generally well-tolerated, but like all medications, it can cause side effects in some people. Most side effects are mild and may fade as your body adjusts to the medication. However, it's important to be aware of what to expect and when to reach out to your doctor.
Common Side Effects
Dizziness or lightheadedness — This occurs because alfuzosin lowers blood pressure. Sit or lie down if you feel dizzy, and rise slowly from a seated position.
Fatigue or weakness — Feeling tired is a common early side effect that often improves within the first few weeks.
Headache — Mild headaches may occur and typically don't require stopping the medication.
Runny or stuffy nose — Some men experience nasal congestion or a runny nose as their body adjusts.
Stomach discomfort — Mild nausea or abdominal discomfort may happen, especially if taken on an empty stomach.
Sexual dysfunction — Some men report erectile dysfunction or reduced sexual desire, though this is not common with alfuzosin compared to other alpha-blockers.
Serious Side Effects
Severe dizziness or fainting — If you experience fainting spells or severe dizziness that interferes with daily activities, contact your doctor right away.
Chest pain or pressure — This is rare but serious and requires immediate medical evaluation.
Allergic reaction — Signs include rash, itching, swelling of the face or throat, or difficulty breathing. Seek emergency care if you experience these symptoms.
Irregular heartbeat — Palpitations or a noticeably fast or fluttering heartbeat should be reported to your healthcare provider.
Vision problems — Although uncommon, some alpha-blockers have been associated with eye surgery complications in certain conditions like cataracts.
When to Seek Medical Attention
Contact your doctor if common side effects persist for more than a few weeks or become bothersome. Seek immediate medical attention if you experience severe dizziness, fainting, chest pain, difficulty breathing, or signs of an allergic reaction. If you're unsure whether a symptom warrants a call to your doctor, it's always better to check. Your healthcare provider can help determine whether to continue, adjust the dose, or try a different medication.

Important: Don't stop taking alfuzosin without talking to your doctor, even if you feel better. Stopping suddenly may cause your symptoms to return. If you miss a dose, skip it and take your next dose at the regular time—never double up on doses. It may take 4 to 6 weeks to notice improvement in urinary symptoms, so patience is important.

Drug Interactions
Alfuzosin can interact with other medications and substances, which may change how well it works or increase the risk of side effects. Always tell your healthcare provider about all medications, supplements, and vitamins you take before starting alfuzosin.
Blood Pressure Medications
Taking alfuzosin with other blood pressure-lowering drugs (like ACE inhibitors, beta-blockers, or calcium channel blockers) may cause blood pressure to drop too much, leading to dizziness or fainting. Your doctor may adjust doses or monitor your blood pressure closely.
Moderate or Strong CYP3A4 Inhibitors (Ketoconazole, Itraconazole, Ritonavir)
These medications slow down how your body breaks down alfuzosin, causing higher levels to build up in your system. This increases the risk of side effects like dizziness and low blood pressure. Your doctor may recommend avoiding these combinations or lowering your alfuzosin dose.
Phosphodiesterase-5 Inhibitors (Sildenafil, Tadalafil)
Using alfuzosin with erectile dysfunction medications may cause excessive drops in blood pressure, dizziness, or fainting. Tell your doctor if you use these drugs so they can advise on safe use together.
Cimetidine (an Antacid)
This medication can increase alfuzosin levels in your body. If you take cimetidine for heartburn or acid reflux, let your healthcare provider know so they can monitor you for increased side effects.
Alcohol
Drinking alcohol while taking alfuzosin may increase dizziness, lightheadedness, and fainting. It's best to limit or avoid alcohol while on this medication.

Frequently Asked Questions
Get answers to common questions about Uroxatral (generic alfuzosin).
Most men begin noticing improvement in urinary symptoms within 2 to 4 weeks, but full benefits may take 4 to 6 weeks. If you don't see improvement after 8 weeks, contact your doctor. They may adjust your dose or recommend a different treatment. Patience is important—don't assume the medication isn't working until you've given it adequate time.
Alfuzosin lowers blood pressure, so if you have heart disease or take heart medications, discuss this carefully with your cardiologist or primary care doctor. They'll review your current medications and may adjust doses or monitor your blood pressure more closely. In some cases, alfuzosin is safe; in others, a different medication may be better suited for you.
Alfuzosin is less likely than some other alpha-blockers to cause erectile dysfunction, but it can happen in some men. If you experience sexual side effects, don't stop the medication without talking to your doctor—they may adjust your dose, switch you to a different alpha-blocker, or recommend additional treatment. Sexual function often improves once you adjust to the medication.
Yes. Generic vs. Brand-Name Drugs explains that generic alfuzosin contains the same active ingredient and works identically to brand-name Uroxatral.

If you remember within a few hours, take the missed dose with food. If it's almost time for your next dose, skip the missed one and resume your regular schedule the next day.
