Flomax, generically known as tamsulosin hydrochloride, is an alpha-blocker that doctors prescribe to treat the symptoms of an enlarged prostate in men, according to WebMD. It relaxes muscles in the bladder and prostate and allows easier urination. Doctors also prescribe it for both men and women to help pass kidney stones through urination.
Flomax does not shrink the prostate gland; it only treats the symptoms, states Mayo Clinic. The typical dose is .4 milligrams taken once a day. Those with an allergy to sulfa drugs should use this medication with caution due to an increased risk of allergic reaction. Those with advance liver and kidney disease should also use it with caution due to slower clearance from the body. Side effects include dizziness, light-headedness, drowsiness, runny or stuffy nose, and ejaculation problems, states MedicineNet.
Benign prostatic hyperplasia, or BPH, is the medical term for an enlarged prostate gland, notes Drugs.com. The condition causes the prostate to become larger than usual. The gland wraps around the urethra, and can squeeze it, causing the urinary symptoms common to the disorder. Symptoms include a weak urine stream, an inability to empty the bladder, frequent urination, urgency, and a urine flow that starts and stops. The condition is common in men over 45 but rarely causes problems before the age of 60.
