Tadalafil (Cialis®) is a prescription medication that was initially licensed to treat erectile dysfunction. Later, it was also approved for the treatment of bladder symptoms due to an enlarged prostate.
(Please note that this article refers specifically to Cialis, the original tadalafil product that is approved for treating erectile dysfunction and an enlarged prostate. For information about the tadalafil product used to treat pulmonary arterial hypertension, please see Adcirca Uses.)
Erectile dysfunction (ED), also known as impotence, is defined as a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Basically, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse. When prescribed for this use, tadalafil can be taken only when desired (about an hour before sexual activity) or on a daily basis (to be "ready" for sex at any time).
An enlarged prostate (known medically as benign prostatic hyperplasia, benign prostatic hypertrophy, or BPH) is very common among older men. The prostate gland, located below the bladder, is part of the male reproductive system. Importantly, the urethra (the canal that takes urine out of the body) runs through the prostate.
The prostate begins growing during puberty and continues to grow throughout most of adulthood. Usually, this is not a problem until men reach their 50s or 60s. When the prostate becomes too large, it can press against the urethra, causing problems with urination. Specific BPH symptoms may include:
- Frequent urination (urinary frequency)
- Difficulty starting a urine stream (urinary hesitancy)
- Difficulty fully emptying the bladder
- Needing to get up several times at night to urinate (nocturia)
- Painful urination (dysuria)
- A weak urine stream
- Dribbling after urinating.
Treatment for BPH includes "watchful waiting" (doing nothing, especially if symptoms are not bothersome), medication, and surgery. Although it is not a cure for BPH and does not shrink the prostate (like a few other medications can do), tadalafil effectively treats BPH symptoms. Also, since BPH and erectile dysfunction often occur together, tadalafil can be an ideal treatment for both conditions at the same time. When used to treat BPH, tadalafil is taken on a daily basis.
