Flomax is prescribed to treat the symptoms of an enlarged prostate--a condition technically known as benign prostatic
hyperplasia or BPH. The walnut-sized prostate gland surrounds the urethra (the duct that drains the bladder). If the
gland becomes enlarged, it can squeeze the urethra, interfering with the flow of urine. This can cause difficulty in
starting urination, a weak flow of urine, and the need to urinate urgently or more frequently. Flomax / Flomaxtra doesn't
shrink the prostate. Instead, it relaxes the muscle around it, freeing the flow of urine and decreasing urinary symptoms.
