Tamsulosin is part of the alpha blocker class of medication commonly used as a course of treatment for symptomatic benign prostatic hyperplasia (otherwise known as BPH). It has also been used to assist the passage of kidney stones and, along with other measures, has be utilised in helping with urinary retention.
Tamsulosin, in common with other alpha blockers, works by causing the muscles in the bladder neck, and muscle fibers in the prostate to relax, which makes it easier for the body to naturally expel urine.
Though often prescribed for kidney stones, tamsulosin is only effective on stones in a certain range of sizes. Specifically, the drug has proven effective for stones that are less than 10 millmeters (mm) but more than 4 mm in size. Naturally this limits the effectiveness of tamsulosin in all cases, but within its range it is considered a very useful way of augmenting treatment for the condition.
Tamsulosin is prescribed for patients suffering from acute urinary retention. Patients who have had their catheter removed have been shown to void urine more successfully when placed on a course of tamsulosin. Likewise, they have also be shown to be less at risk of need the catheter to be reapplied. This is of immense benefit to patients, as reinsertion of the catheter can be both painful and uncomfortable.
Tamsulosin is often prescribed in conjunction with dutasteride, the combination of drugs proving to increase the benefits of treatment in patients with symptomatic benign prostatic hyperplasia than either drug on its own.
Tamsulosin is only available with a prescription from your doctor or health care professional.

Tamsulosin is not intended for use by the pediatric population, and should not be administered to children.
Appropriate medical studies have not shown any geriatric-specific problems with tamsulosin that would limit the drug’s usefulness in the elderly.
Animal studies have shown no indication of tamsulosin causing harm to the fetus during pregnancy, however, there have not been adequate studies among pregnant women to demonstrate if this is the case in humans.
There have been no adequate studies performed among women to determine infant risk when using tamsulosin whilst breastfeeding. You should weigh the benefits of the medication against all potential risks before deciding to take this drug when breastfeeding.
It is essential that your prescribing doctor check your progress throughout your course of treatment, to ensure that tamsulosin is working correctly for you, and to check for any sign of unwanted side effects.
You may experience dizziness, fainting, or light-headedness after you take tamsulosin, particularly when getting up from a sitting or a lying position. Standing up slowly might lessen this problem. Should you start to feel dizzy, lie down on the floor so that you do not faint. Then sit still for a while before attempting to stand again, to prevent dizziness from returning.
Because of the above possible reaction, be sure that you know how you react to tamsulosin before you use machinery, drive, or perform any other activity that could be dangerous if you are not fully alert.

If you intend to have glaucoma or cataract surgery, be sure to tell your ophthalmologist that you are taking tamsulosin, or that you have taken it in the last nine months. A serious eye condition known as Intraoperative Floppy Iris Syndrome (or, IFIS) has been seen to occur in some patients who were undergoing a course of tamsulosin, or who had just finished such a course when they underwent glaucoma or cataract surgery.

Tamsulosin is an alpha blocker used in the treatment of symptomatic benign prostatic hyperplasia (BPH), kidney stones, and as complementary medication to assist patients suffering from urinary retention, following the removal of their catheter. Its effectiveness in treating kidney stones is somewhat limited, on being of use in the removal of kidney stones within a certain size range.
It works by relaxing the bladder and prostate muscles, allowing the body to expel urine more easily and naturally. This effect is what makes it such a beneficial secondary treatment for patients who have recently had their catheter removed.
