Enlarged Prostate: Should I Take Medicine?

Get the facts

Your options

  • Take prescription medicine to help your urinary symptoms.
  • Don't take medicine. Instead, try watchful waiting and manage your symptoms at home.

Urinary symptoms include needing to urinate often, having a weak urine stream, or having trouble starting a urine stream.

Watchful waiting and medicines are usually the first things considered for an enlarged prostate. Sometimes surgery is needed for more serious symptoms.

Key points to remember

  • Typically, you don't need medicine for an enlarged prostate unless the symptoms bother you or you have other problems such as bladder infections or bladder stones.
  • About 4 out of 10 men find that their symptoms improve without treatment. That means that 6 out of 10 men need medicine or surgery to help their symptoms.footnote 1
  • The side effects of medicine may bother you more than your symptoms.
  • Taking medicine may help keep you from needing surgery in the future.footnote 2
FAQs

What is benign prostatic hyperplasia?

Benign prostatic hyperplasia, or BPH, is better known as an enlarged prostate. It happens to almost all men as they age. It is not cancer.

An enlarged prostate is usually harmless, but it often causes problems with urination. About half of all men older than 75 have some symptoms.

The most important thing in deciding whether to get treatment is how much the symptoms bother you and how much they affect your quality of life.

What medicines are used to treat an enlarged prostate?

Medicines are sometimes used to help relieve bothersome, moderate to severe urination problems caused by an enlarged prostate. If you stop using medicine, the symptoms will probably return.

Medicine choices include:

  • Alpha-blockers, such as tamsulosin (Flomax) or terazosin (Hytrin), which relax muscle tissue.
  • 5-alpha reductase inhibitors, such as dutasteride (Avodart) and finasteride (Proscar), which shrink the prostate.
  • A combination of the two, which, when used long-term, may help your symptoms more than either medicine alone.footnote 3
  • Phosphodiesterase-5 (PDE-5) inhibitors, such as tadalafil (Cialis), may help reduce BPH symptoms whether or not you have erection problems. PDE-5 inhibitors are well known medicines for erection problems.footnote 4
  • Anticholinergic and antispasmodic medicines such as oxybutynin (for example, Ditropan) and tolterodine (Detrol) calm the nerves that control bladder muscles and increase bladder capacity. Taking an alpha-blocker medicine with an anticholinergic may help with symptoms better than either medicine alone.footnote 5, footnote 6

5-alpha reductase inhibitor

Alpha-blocker

  • For some men, it can shrink the prostate.
  • It may not work as well for symptom relief as alpha-blockers.footnote 2
  • Most men have improvement in symptoms with the medicine.footnote 7
  • Symptoms get better in about 6 months.
  • It may lower your risk of needing catheterization or surgery for blocked urine flow.footnote 2
  • Side effects include:
    • Reduced sex drive.
    • Less semen when you ejaculate.
    • Trouble getting an erection.
  • It doesn't affect prostate size.
  • It may work better than 5-alpha reductase inhibitors for symptom relief.footnote 2
  • Most men have improvement in symptoms with the medicine.footnote 7
  • Symptoms get better in 2 to 3 weeks.
  • For some people, it also helps lower high blood pressure a little.
  • Side effects include:
    • Weakness or fatigue.
    • Lightheadedness, dizziness, or fainting when you stand up.
    • A slight decrease in blood pressure.
    • Headaches and a stuffy nose.

What can you do if you don't want to take medicine?

If you don't want to take medicine, you can try watchful waiting while managing your symptoms at home.

Watchful waiting means you have regular checkups to be sure that your symptoms aren't getting worse. And you try making these small changes to your lifestyle to control your symptoms:

  • Don't try to rush your urination. Try to relax while using the bathroom.
  • Practice "double voiding." Urinate as much as you can. Then relax for a few moments and try to go again.
  • Don't limit your fluid intake to avoid having to urinate. Drink fluids throughout the day. Limit fluids in the evening if you often wake up at night to urinate.
  • Avoid caffeine and alcohol. They make your body try to get rid of water and can make you urinate more often.
  • If you can, avoid medicines that make your symptoms worse, such as nonprescription antihistamines, decongestants (including nasal sprays), and allergy pills. Talk to your doctor first.

Some men try dietary supplements for BPH, such as saw palmetto or beta-sitosterol. But scientific studies don't show that saw palmetto helps with urinary problems or that beta-sitosterol is safe or helps over the long term.

About 4 out of 10 men find that their symptoms improve without treatment. This means that 6 out of 10 men need medicine or surgery to help their symptoms.footnote 1

Why might your doctor recommend medicine for BPH?

Your doctor may recommend taking medicine for BPH if:

  • You have tried to manage your symptoms through watchful waiting, but they still bother you.
  • You have a large prostate, and your doctor feels that you may be at risk for urinary retention. (Urinary retention means you can't urinate because your prostate blocks your bladder from emptying.)

Personal stories about using medicine for benign prostatic hyperplasia

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

I've been having a lot of trouble getting a good night's sleep now that I have this enlarged prostate. I'm up 4 or 5 times a night to go to the bathroom, and then both my wife and I are tired all day. My doctor said these medicines often help with that problem, so I'm going to try them. Even if I still had to get up a couple of times a night, I would get more rest and have more energy during the day.

Jake, age 61

When I started having problems urinating, my first thought was that it had to be cancer. My brother-in-law had similar symptoms, but he ignored them for a long time and eventually was diagnosed with prostate cancer. I decided not to ignore them, so I went right to my doctor. He did a rectal exam and a PSA test and said that he was confident that my prostate was just enlarged and that it did not appear that I had cancer. He said if I wanted something to treat the symptoms, he could prescribe medicine. But I was just happy that the problem wasn't from cancer, so I decided to manage the symptoms on my own for now.

Jim, age 65

I've been able to manage my BPH symptoms on my own for a couple years. They didn't bother me that much at first, and the tips my doctor gave me about limiting fluids and avoiding nonprescription decongestants really helped. But these days, my symptoms seem to be getting worse, and I'm tired of dealing with them. I know the medicine can have side effects, but I'm going to give it a try.

Michael, age 54

Several months ago, I started taking medicine to treat my prostate symptoms. The doctor said that most men don't have serious side effects, but I guess I'm one of the few who do. Feeling dizzy, lightheaded, and tired was affecting me more than my prostate symptoms were, so I decided to stop taking the medicine. I found that my symptoms actually got a little better by themselves. For now, I'm managing okay with home treatment. My doctor and I will keep talking about other options if my symptoms get worse and I decide I want to try something different.

Carl, age 58
