Let's take a minute and talk about your medication.   

This is tamsulosin, and you should take your dose 30 minutes after a meal. You should swallow the capsule whole, and don't crush or chew it.  

Tamsulosin is used to treat the symptoms of an enlarged prostate, like a weak urine stream, or sudden and frequent needs to urinate. 

At first, some side effects could occur. You could feel dizzy, and standing slowly after you've been sitting or lying down should help. It is also a good idea to avoid activities that require you to be alert, like driving, until you know how it affects you.  It could cause a runny nose, or a decrease in semen.  This normal and should go away.  But, if these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist.  

In very rare cases, a painful erection that won't go away can occur. If this happens, you should get medical help right away.   

For best results, continue taking tamsulosin and follow your doctor's advice for routine health screenings for prostate cancer.
