What is Flomax CR?

Flomax (tamsulosin) is a prescription drug that treats symptoms of frequent urination in men with BPH (benign prostatic hyperplasia). Flomax 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 Flomax exactly as prescribed.

  • Flomax is typically taken once daily and should be taken about 30 minutes after eating.
  • Swallow whole. Do not crush or chew.
  • You may need to check your blood pressure often while taking this medication.
  • You may feel very dizzy when you first wake up. Take care when first sitting or standing up.


Flomax should only be used by men and is not approved to be used by anyone younger than 18.

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

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

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

  • Liver or kidney disease
  • Low blood pressure
  • Sulfa drug allergy
  • Prostate cancer

Side Effects of Flomax

  • Headache, chest pain, back pain
  • Flu symptoms (fever, chills, body aches)
  • Cold symptoms (cough, stuffy nose, sore throat)
  • Sexual side effects (decreased sex drive, abnormal ejaculation)

  • Light-headedness or fainting
  • Erection that’s painful or lasts more than 4 hours
  • Skin reaction – Sore throat, fever, swelling in face, burning eyes, skin pain, blistering and peeling rash


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

Dizziness is most common when you first start taking Flomax 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 Flomax, avoid strenuous exercise, driving, and operating heavy machinery.

How quickly does Flomax start to work?

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