Signs and symptoms of benign prostatic hyperplasia (BPH)
Alfuzosin ER (Uroxatral) is an alpha-1 blocker. It treats BPH by relaxing certain muscles in the prostate and bladder, which allows urine to flow more easily.

Interacts with some common medications, such as blood pressure medications
Your body absorbs alfuzosin ER (Uroxatral) better with food. Take alfuzosin ER (Uroxatral) after the same meal each day. Swallow it whole. Don't chew, break, or crush the tablet.
Alfuzosin ER (Uroxatral) can cause a sudden drop in your blood pressure when you stand. This can cause dizziness, vertigo (feeling like you’re spinning), or fainting. If you feel these symptoms, sit or lie down right away so you don't fall.
Alfuzosin ER (Uroxatral) can raise your risk of falls since it causes dizziness. If you fall down and hit your head or are in pain after a fall, the safest choice is to seek medical care right away. This is because there could be bleeding inside the body, and it’s best to have your provider check for these injuries. This is particularly important if you’re taking blood thinners, which can raise your risk for bleeds that are difficult to stop.
Although rare, alfuzosin ER (Uroxatral) can cause painful erections lasting longer than 4 hours (priapism). If this happens, get medical care right away. If this isn't treated, it can cause permanent erection problems.
If you've just started to take alfuzosin ER (Uroxatral) for prostate problems, ask your provider about prostate cancer screening if you haven't already. Some symptoms of prostate cancer are very similar to BPH, such as weak urine stream or feeling like your bladder is full even after you've urinated. It's best to get a check up to rule out prostate cancer when you first get diagnosed with BPH.
Alfuzosin ER (Uroxatral) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Taking medications for high blood pressure, chest pain, or erectile dysfunction | History of low blood pressure or a drop in blood pressure after taking other medications
Alfuzosin ER (Uroxatral) can cause a big drop in blood pressure when you stand up from a seated or lying down position. This might make you feel dizzy or it can make you faint. It's more likely to happen within hours after you take your dose. Your risk is higher if you're also taking other blood pressure medications or erectile dysfunction medications at the same time. Be cautious with your activities when you first start alfuzosin ER (Uroxatral) or when your provider raises your dose.
Alfuzosin ER (Uroxatral) can interact with many medications, so make sure you let your provider know about all the medications you're taking before you start alfuzosin ER (Uroxatral).
For example, taking alfuzosin ER (Uroxatral) with medications for erectile dysfunction might cause your blood pressure to drop too low, which can be dangerous.
You'll need to avoid certain medications, such as clarithromycin (Biaxin), ketoconazole, and some HIV medications completely when taking alfuzosin ER (Uroxatral). These medications can cause the level of alfuzosin ER (Uroxatral) to rise too high in your body and raise your risk of side effects.
Alfuzosin ER (Uroxatral) is broken down by your liver so it can be cleared from your body. Don't take alfuzosin ER (Uroxatral) if you have moderate to severe liver problems. Check with your provider if you aren't sure how severe your liver problems are.
Also, if you've kidney problems, let your provider know. Depending on how serious your condition is, you might not be able to take alfuzosin ER (Uroxatral).
If you have chest pain or heart rhythm problems (long QT), let your provider know. They'll likely stop alfuzosin ER (Uroxatral) for you if you have chest pain or if your chest pain worsens. And they might need to monitor your heart more often if you have heart rhythm problems.
In some very rare cases, alfuzosin ER (Uroxatral) can cause a painful erection (also known as priapism) that continues for more than 4 hours. If this happens to you, contact your provider right away to avoid the risk of permanent erectile dysfunction.
Risk factors: Cataract surgery
If you take alfuzosin ER (Uroxatral) and plan to get cataract eye surgery, let your provider know. In some rare cases, this medication can cause changes to your iris, a condition called Intraoperative floppy iris syndrome (IFIS). Keep in mind that alfuzosin ER (Uroxatral) is probably less likely to cause IFIS than other medications used to treat BPH, like tamsulosin. You don’t need to stop taking alfuzosin ER (Uroxatral) before the surgery, but your surgeon needs to adjust how they perform the operation. Letting your provider know ahead of time can help them prepare accordingly.
