Learn about enlarged prostate (BPH) symptoms below, so you can relieve them

Frequent urination


Frequent urination is normally considered the need to urinate more than 8 times a day.9 You may find yourself going again and again throughout the day and night.

How does it affect you?

  • Frequent urination may affect your daily routine, and force you to make compromises
  • Activities like sitting through business meetings, movies or sporting events without being interrupted by the need to go to the bathroom become difficult
  • You may find yourself planning to use the bathroom when you don’t really have to go
Nighttime urination


Waking more than once a night to urinate is a condition known as nocturia.9 You may have a difficult time sleeping through the night, because you have to get up to go to the bathroom.

How does it affect you?

  • This disruptive symptom may leave you feeling exhausted, irritable, and fatigued
  • This makes staying alert and focused throughout the day much more difficult
  • These frequent nighttime trips to the bathroom can also affect your partner’s sleep (you may find yourself sleeping on the couch)


Urgency is the sudden and overwhelming need to urinate immediately.13 You may find that it’s difficult to hold your urine for very long.

How does it affect you?

  • Some men feel uneasy and troubled by the sudden urge to urinate
  • Planning your drinking and travel habits around bathroom access are typical coping mechanisms
  • Rearranging your life due to the sudden urge to go can be annoying and inconvenient
  • Urgency makes it difficult to focus on much else aside from your urinary habits
Incomplete emptying
(of the bladder)


Incomplete emptying of the bladder occurs when you urinate, but it still feels as if your bladder is not completely empty.13 This feeling can happen even after you’ve just finished going. If left untreated severe enlarged prostate symptoms may lead to urinary tract infections.1

How does it affect you?

  • This uncomfortable symptom can be frustrating and may contribute to frequent urination
  • Without a satisfying go, it can be difficult to focus on daily activities
  • You may even view the discomfort caused by incomplete emptying of the bladder as painful
Weak stream


Weak stream occurs when the enlarged prostate constricts urine flow through the urethra.1 Instead of a steady stream of urine, a weak trickle is all that flows out.

How does it affect you?

  • You may find that you’re embarrassed by a
    weak stream
  • It can also be aggravating to wait for your urine to flow when your stream is much slower than normal


Even though you have the urge to go, you may find that it is difficult to start your
urine stream.13 This delay in your stream may cause you to push or strain in order
to begin urinating.13

How does it affect you?

  • This frustrating symptom causes discomfort
  • Men often confuse this symptom with prostate cancer, causing them to worry before diagnosis


Intermittency is what occurs when your urine stream starts and stops. This starting and stopping can often lead to urinary incontinence, or leaking and dribbling urine before or after you go.13

How does it affect you?

  • Intermittency, leaking, and dribbling can
    be both annoying and embarrassing
  • Dribbling may also cause you to change
    your underwear multiple times a day, or
    prevent you from wearing light-colored pants

    How can I fix my urinary issues?

    Fortunately, an enlarged prostate is easy to treat. Use the Symptom Calculator to measure the severity of your symptoms, and discuss the results with your urologist or health care provider. Ask your urologist and pharmacist for RAPAFLO® by name. By taking RAPAFLO® once a day, you can feel fast and continued relief.2,3

    What is a Symptom Calculator?

    The Symptom Calculator is a way to track and measure your symptoms. It was developed from the American Urological Association’s standard IPSS Test (International Prostate Symptom Score), as a quick and easy way for you to assess your own urinary symptoms. All you need to do is answer the questions and our interactive tool will calculate the score for you.

    After receiving your score, it’s important to share the results with your urologist or health care provider. Our interactive Symptom Calculator makes it easy to download or print your results.

    Once you begin treatment, track your symptoms’ progress by waiting 30 days to recalculate your score, and then compare your original results with the new ones.

    Find out if you’re:
    0-7: Mildly symptomatic
    8-19: Moderately symptomatic
    20-35: Severely symptomatic

    Can RAPAFLO® help?

    RAPAFLO® is a targeted treatment that works quickly, improving urine flow within 2 to 6 hours of taking the first dose and providing significant relief within 3 to 4 days.2,3 RAPAFLO® not only works fast, but it works long term as well. Studies show that at the one-year mark patients have shown sustained relief and continued symptom improvement.2,3,*

    *Data from patients who received RAPAFLO® for 12 weeks in a double-blind, placebo-controlled trial and for an additional 40 weeks in an open label extension study.

    What are normal urinary habits?

    Typically, most people urinate 4 to 8 times a day.9 Going more than 8 times a day or needing to wake up more than once during the night to urinate are considered signs of frequent urination.9 Use our Symptom Calculator to measure your symptoms, and then talk to your urologist or health care provider if you are experiencing frequent urination or any of the other symptoms of an enlarged prostate.

    Is this cancer?

    An enlarged prostate is NOT cancer. Men with an enlarged prostate do not seem more likely to get prostate cancer.1
    But many prostate cancer symptoms are the same as those of an enlarged prostate.1
    It is important to talk to your urologist or health care provider about any urinary symptoms you may be experiencing. They will perform tests to help confirm your urinary symptoms are due to an enlarged prostate and not prostate cancer.1

    Are these symptoms common for men my age?

    An enlarged prostate is one of the most common problems men deal with as they grow older.11 The size of a man’s prostate continues to grow over time. Symptoms from an enlarged prostate typically develop after age 40.1

    About 25% of men in their 40s, 50% of men in their 50s and 60s, and up to 90% of men in their 70s and 80s have some symptoms of an enlarged prostate.

    Will my symptoms get worse if I don’t do anything?

    Your urinary symptoms will most likely not go away without treatment. The prostate will continue to grow and press against the urethra causing it to constrict and reduce urine flow. Left untreated, severe urinary symptoms can lead to more serious complications such as the inability to urinate, urinary tract infections, as well as bladder and kidney damage.1 The effects of an untreated enlarged prostate may also affect some men’s sexual function and desire.
