MEDICATIONS FOR BPH SYMPTOMS

There are two kinds of prescription pills, known as alpha blockers and 5-alpha reductase inhibitors. They can be taken either alone or as combination therapy, which may result in greater effectiveness and symptom relief. Pills may require several weeks to 6 months to take effect. They also may have side effects, and their long-term effectiveness can be limited. Over the long run, the continual use of pills can be costly.

Alpha Blockers

These pills are often prescribed for mild to moderate BPH symptoms. Alpha blockers relax the muscle tissue of the prostate and the bladder neck, allowing urine to flow from the bladder more easily.
These pills include:

  • Hytrin® (terazosin hydrochloride)
  • Cardura® (doxazosin mesylate)
  • Flomax® (tamsulosin hydrochloride)
  • Minipress® (prazosin hydrochloride)
  • Uroxatral® (alfuzosin hydrochloride)

Alpha blockers relieve symptoms within a few weeks, but do not stop the process of prostate enlargement. Side effects vary with each individual and medication.

Common side effects of alpha blockers include:

  • Weakness or fatigue
  • Headaches
  • Nasal congestion
  • Dizziness

Sexual side effects include:

  • Failure to ejaculate,
  • Retrograde (or internal) ejaculation,
  • Less semen to be ejaculated.

Side effects disappear once the medication is stopped.


 

5-Alpha Reductase Inhibitors

These medications work best with men who have significantly enlarged prostates (BPH). Men with smaller prostates see less benefit. 5-alpha reductase inhibitors inhibit the effect of certain male hormones, which slows the rate of prostate enlargement. In some cases, they even shrink the size of the prostate.

Two medications in this category are:

  • Proscar® (finasteride)
  • Avodart® (dutasteride)

5-alpha reductase inhibitors may take from 3 to 6 months before symptom improvements are noticed.

While 5-alpha reductase inhibitors are generally considered safe and well tolerated, common side effects include:

  • Less semen to be ejaculated
  • The inability to get an erection (impotence).
