Uroxatral is a prescription drug that treats symptoms of frequent urination in men with BPH (benign prostatic hyperplasia). Uroxatral belongs to a class of drugs called alpha-blockers, and works by relaxing muscles in the prostate and bladder.

Always follow your doctor’s instructions and use Uroxatral exactly as prescribed.

• Take just after a meal. Do not use Uroxatral on an empty stomach.
• Swallow whole. Do not crush or chew.

Some men experience dizziness or fainting when they first start taking Uroxatral. Take care when driving, standing for long periods, or during exercise. Getting up quickly from a standing or lying position may worse dizziness.

Uroxatral may affect pupils during cataract surgery. Inform your eye doctor that you’re using Uroxatral, but don’t stop using it unless directed by a doctor.

Before taking Uroxatral, inform your doctor if you have any of the following:

• Liver or kidney disease
• Low blood pressure
• Prostate cancer
• Long QT syndrome

Common side effects of Uroxatral include:

• Headache
• Dizziness
• Tiredness

Contact your doctor if you experience these more serious side effects:

• Light-headedness or fainting
• Erection that’s painful or lasts more than 4 hours
• Upper abdominal pain, dark urine, loss of appetite, light colored stools, jaundice
• Chest pain

What should I do if Uroxatral is causing me to feel dizzy?

Dizziness is most common when you first start taking Uroxatral, and should improve over time. Take care to get up slowly from a lying or sitting position, especially first thing in the morning. Until you’ve adjusted to Uroxatral, avoid strenuous exercise, driving, and operating heavy machinery.

How quickly does Uroxatral start to work?

Most people will have symptom relief within a week of taking Uroxatral. Talk to your doctor if you haven’t noticed any changes after 2 weeks of using Uroxatral.
