Alfuzosin Dosage: What You Need to Know

If you’ve been prescribed alfuzosin for an enlarged prostate, the biggest question is usually “how much should I take?” The short answer: most adults start with 10 mg once daily. That’s the dose that studies show works well for relieving urinary symptoms without causing too many side effects.

Take the tablet with a full glass of water after the same meal each day. Consistency helps your body keep a steady drug level, which means fewer ups and downs in symptom control.

How to Take Alfuzosin Properly

Here’s a quick checklist you can keep by the sink:

• Swallow the tablet whole – don’t crush or chew it.
• Drink at least 8 ounces of water.
• Take it after the same meal (breakfast, lunch, or dinner) every day.
• If you miss a dose, take it as soon as you remember – but if it’s almost time for the next dose, skip the missed one and stay on schedule.

Don’t double up just because you forgot; that can raise the risk of dizziness or low blood pressure.

When Doctors May Adjust the Dose

While 10 mg is standard, some doctors start new patients on 5 mg, especially if they’re over 80, have liver problems, or are taking medicines that affect the same liver enzymes (CYP3A4). If you have kidney disease, the dose usually stays the same, but your doctor might monitor you more closely.

Common reasons for a dose change include:

• Persistent side effects like faintness, headache, or a racing heart.
• Not enough relief after a few weeks – sometimes a higher dose or a different medication is needed.
• Adding a new drug that could interact (e.g., certain antifungals, antibiotics, or HIV meds).

Always tell your pharmacist about every prescription and over‑the‑counter product you use. A quick drug‑interaction check can prevent surprises.

Most people feel better within 2–4 weeks of starting alfuzosin. If you’re still having trouble after a month, call your doctor. Sometimes the timing of the dose needs tweaking, or the doctor might suggest a combination therapy.

Remember, alfuzosin works by relaxing the muscles in the prostate and bladder neck. It doesn’t shrink the prostate, so lifestyle changes – like cutting back on caffeine and staying hydrated – still matter.

In short, stick to the once‑daily 10 mg routine, take it with water after the same meal, watch for dizziness, and keep your doctor in the loop if anything feels off. That’s the simplest way to get the most benefit from alfuzosin while keeping side effects low.
