GENERIC NAME: terazosin
BRAND NAME: Hytrin (discontinued brand)
DRUG CLASS AND MECHANISM: Terazosin belongs to a class of medications called alpha 1 blockers which relax the smooth muscles of the arteries, the prostate, and the bladder neck. Other alpha blockers include doxazosin (Cardura), alfuzosin (Uroxatral), tamsulosin (Flomax), and prazosin (Minipress). Relaxing the smooth muscles of the arteries lowers blood pressure. Relaxing the smooth muscles around the bladder neck relieves urinary obstruction caused by an enlarged prostate (prostate hypertrophy). Terazosin relaxes the smooth muscles of the bladder neck and the prostate, increasing urine flow. The FDA approved terazosin in 1987.
PRESCRIBED FOR: Terazosin is used to treat the symptoms of urinary obstruction due to an enlarged prostate caused by benign prostatic hypertrophy (BPH). Terazosin also is used alone or in combination with another blood pressure medication to treat high blood pressure.
SIDE EFFECTS: Commonly reported side effects include:
- postural hypotension,
- swelling of the legs (edema),
- nasal congestion,
- decreased libido,
- impotence, and
- blurred vision.
