Silodosin - oral

Patient Medicine Information
Why do I need this medicine?
Silodosin is used to treat symptoms of an enlarged prostate gland in men. This enlargement of the prostate gland is called benign prostatic hyperplasia (BPH). The enlarged prostate gland may cause problems when you pass urine.

It relaxes the muscles in the prostate gland and bladder. This helps to improve symptoms such as difficulty in passing urine, slow or interrupted flow of urine, frequent urination and dribbling after passing urine.
How do I take this medicine?
Take Silodosin exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Take it together with food or immediately after a meal. Try to take it at the same time each day.

Silodosin must be taken regularly for it to be effective. Continue taking this medicine even when you feel better. Do not stop taking it unless instructed by the doctor.
What should I do if I have forgotten to take this medicine?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
