Flomax Oral

Uses
This medication is used to treat the symptoms of a prostate gland condition called BPH (benign prostatic hyperplasia, also known as enlarged prostate). Tamsulosin is an alpha-blocker that works by relaxing the muscles in the bladder neck and prostate. Relaxing these muscles leads to relief of symptoms of BPH such as the feeling of needing to urinate frequently or urgently, weak stream, difficulty in beginning the flow of urine, and the need to urinate during the middle of the night. This medication should not be used to treat high blood pressure.

Take this medication by mouth, usually once daily. Take the first dose at bedtime to minimize the chances of getting dizzy or fainting. After the first dose, take your regularly scheduled dose 30 minutes after the same meal each day, or take exactly as directed by your doctor. Swallow this medication whole.
