1.    What Tamsumac is and what it is used for

The active ingredient in Tamsumac is tamsulosin hydrochloride. It acts by relaxing the muscles in the prostate and urethra (the tube that carries urine to the outside), and lets urine pass more readily through the urethra and aids urination.

In the prostate gland, bladder and urethra there are specialised cells containing alpha1A-receptors that cause the muscles in the urethra to tighten. Tamsumac is an alpha1A-adrenoceptor blocker, which reduces the action of these specialised cells and relaxes the muscles making it easier to pass water.

Tamsumac is used in men for the treatment of the complaints of the lower urinary tract associated with an enlarged prostatic gland (benign prostatic hyperplasia). These symptoms include difficulty in starting to pass water, frequent trips to the toilet to pass water, a feeling of not completely emptying the bladder and having to get up several times in the night to pass water.

2.    What you need to know before you take Tamsumac Do not take Tamsumac:

•    If you are allergic (hypersensitive) to tamsulosin or any of the other ingredients of Tamsumac (listed in section 6).

•    if you have a severe liver condition.

•    if you have ever fainted or felt dizzy when suddenly sitting or standing up. Dizziness can sometimes occur when taking Tamsumac, particularly if you are also taking other alpha-blockers. If you do feel weak or dizzy make sure you sit or lie down straight away until the symptoms have disappeared.

Warnings and precautions

Talk to your doctor or pharmacist before taking Tamsumac.

Take special care with Tamsumac (and speak to your doctor)

•    If you have kidney problems

•    If you are undergoing or have been scheduled for eye surgery because of cloudiness of the lens (cataract) or increased pressure in the eye (glaucoma).

Please inform your eye specialist that you have previously used, are using or are planning to use tamsulosin. The specialist can then take appropriate precautions with respect to medication and surgical techniques to be used. Ask your doctor whether or not you should postpone or temporarily stop taking this medicine when undergoing eye surgery because of a cloudy lens (cataract) or to increased pressure in the eye (glaucoma).

Children and adolescents

Do not give this medicine to children or adolescent under 18 years because it does not work in this population.

Other medicines and Tamsumac

-    Taking Tamsumac together with other medicines from the same class (a1-adrenoceptor antagonists) may cause an unwanted decrease in blood pressure.

-    It is especially important to inform your doctor if you are being treated at the same time with medicines that may decrease the removal of Tamsumac from the body (for example, ketoconazole, erythromycin).

Tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines.

Tamsumac with food and drink

Tamsumac must be taken after breakfast or the first meal of the day.

Pregnancy, breast-feeding and fertility

Tamsumac is not indicated for use in women.

In men, abnormal ejaculation has been reported (ejaculation disorder). This means that semen does not leave the body via the urethra, but instead goes into the bladder (retrograde ejaculation) or ejaculate volume is reduced or absent (ejaculatory failure). This phenomenon is harmless.

Driving and using machines

There is no evidence that Tamsumac affects the ability to drive or to operate machinery or equipment. However, you should bear in mind that dizziness can occur, in which case you should not undertake activities that require attentiveness.

3. How to take Tamsumac

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is 1 capsule per day to be taken after breakfast or the first meal of each day. The capsule must be swallowed whole and not be crunched or chewed. Usually, Tamsumac is prescribed for long periods of time. The effects on the bladder and on urination are maintained during long-term treatment with Tamsumac.

If you take more Tamsumac than you should

Taking too much Tamsumac may lead to an unwanted decrease in blood pressure and an increase in heart rate, with feelings of faintness. Contact your doctor immediately if you have taken too much Tamsumac.

If you forget to take Tamsumac

You may take your daily Tamsumac later the same day if you have forgotten to take it as recommended. If you have missed a day, just continue to take your daily capsule as prescribed. Never take a double dose to make up for a forgotten capsule.

If you stop taking Tamsumac

When treatment with Tamsumac is stopped prematurely, your original


complaints may return. Therefore take Tamsumac as long as your doctor prescribes, even if your complaints have disappeared already. Always consult your doctor, if you consider stopping this therapy.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
