Alfuzosin — fast facts and practical advice for BPH relief
Waking up at night to pee or feeling like your bladder never empties? Alfuzosin is a common prescription that helps men with benign prostatic hyperplasia (BPH) relax the muscles around the prostate and bladder neck so urine flows easier. This page gives straight answers about what alfuzosin does, how people usually take it, and the main safety points to watch for.
How alfuzosin works
Alfuzosin is an alpha-1 adrenergic blocker. That means it relaxes smooth muscle in the prostate and the bladder outlet, lowering resistance when you urinate. Most people notice improvement in urinary symptoms within days to a few weeks. Doctors often prescribe alfuzosin when symptoms bother sleep, daily life, or lead to complications like urinary retention.
How to take it and common dosing
The usual adult dose for the extended-release form is 10 mg once daily, taken right after the same meal each day. Food helps steady absorption and reduces dizziness. Don’t split or crush extended-release tablets. If you miss a dose, take the next scheduled dose and skip the missed one—don’t double up.
Older adults may be more sensitive to side effects, so doctors often start carefully and check blood pressure. If you have liver problems, alfuzosin may not be suitable or your doctor may lower the dose.
What to watch for — side effects and interactions
Common side effects include dizziness, tiredness, headache, and nasal congestion. Dizziness is often from a drop in blood pressure, especially when standing up quickly. Avoid driving or operating heavy machinery until you know how alfuzosin affects you.
Mixing alfuzosin with other blood-pressure-lowering drugs or alcohol can make dizziness and fainting more likely. Also be cautious with medications that block CYP3A4 (for example, strong antifungals or some HIV drugs) because they raise alfuzosin levels and the risk of side effects.
Avoid taking alfuzosin with strong CYP3A4 inhibitors and tell your doctor about all prescriptions and supplements you use. Combining alfuzosin with sildenafil or other PDE5 inhibitors needs medical advice because the combination can lower blood pressure too much in some men.
Serious allergic reactions are rare, but seek immediate care if you get swelling of the face or throat, trouble breathing, or a rash. Call your doctor if you notice prolonged dizziness, fainting, or a sudden change in vision or hearing.
Alfuzosin helps many men feel better by easing urinary flow, but it’s not for everyone. Talk with your doctor about your heart, liver, and current medicines before starting. If you experience troublesome side effects, there are alternative BPH treatments available—ask your clinician which one fits your health and lifestyle best.

As a blogger who cares about health and safety, I want to share some tips on how to safely combine alfuzosin with other medications. First, always consult your healthcare provider before starting any new medication, as they can provide personalized advice based on your medical history. Second, be cautious when taking alfuzosin with blood pressure medications, as it may cause a drop in blood pressure. Third, avoid consuming grapefruit or grapefruit juice while on alfuzosin, as it can increase the concentration of the drug in your body. Lastly, always read the medication labels and follow the directions carefully to ensure safe and effective use.
