Avidart is used to treat men with an enlarged prostate

(benign prostatic hyperplasia) - a non-cancerous growth of the prostate gland, caused by producing too much of a hormone called dihydrotestosterone.

The active ingredient is dutasteride. It belongs to a group of medicines called 5-alpha reductase inhibitors.

As the prostate grows, it can lead to urinary problems, such as difficulty in passing urine and a need to go to the toilet frequently. It can also cause the flow of the urine to be slower and less forceful. If left untreated, there is a risk that your urine flow will be completely blocked (acute urinary retention). This requires immediate medical treatment. In some situations surgery is necessary to remove or reduce the size of the prostate gland. Avidart lowers the production of dihydrotestosterone, which helps to shrink the prostate and relieve the symptoms. This will reduce the risk of acute urinary retention and the need for surgery.

Avidart may also be used with another medicine called tamsulosin (used to treat the symptoms of an enlarged prostate).

Do not take Avidart

•    if you’re allergic (hypersensitive) to dutasteride, other 5-alpha reductase inhibitors, soya, peanut or to any of the

other ingredients of Avidart.

•    if you have a severe liver disease.

Tell your doctor if you think any of these apply to you.

This medicine is for men only. It must not be taken by women, children or adolescents.

Take special care with Avidart

•    In some clinical studies, more patients taking dustasteride and another medicine called an alpha-blocker, like tamsulosin experienced heart failure than patients taking only dustasteride or only an alpha-blocker. Heart failure means your heart does not pump blood as well as it should.

•    Make sure your doctor knows about liver problems. If you have had any illness affecting your liver, you may need some additional check-ups while you are taking Avidart.

•    Women, children and adolescents must not handle leaking Avidart capsules, because the active ingredient can be absorbed through the skin. Wash the affected area immediately with soap and water if there is any contact with the skin.

•    Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking Avidart. If your partner is or may be pregnant, you must avoid exposing her to your semen as dutasteride may affect the normal development of a male baby. Dutasteride has been shown to decrease sperm count, semen volume and sperm motility. This could reduce your fertility.

•    Avidart can affect a blood test for PSA (prostate-specific antigen), which is sometimes used to detect prostate cancer. Your doctor should be aware of this effect and can still use the test to detect prostate cancer. If you are having a blood test for PSA, tell your doctor that you are taking Avidart. Men taking Avidart should have their PSA tested regularly.

•    In a clinical study of men at increased risk of prostate cancer, men taking Avidart had a serious form of prostate cancer more often than men who did not take Avidart. The effect of Avidart on this serious form of prostate cancer is not clear.

•    Avidart may cause breast enlargement and tenderness. If this becomes troublesome, or if you notice breast lumps or nipple discharge you should talk to your doctor about these changes as these may be signs of a serious condition, such as breast cancer.

Contact your doctor or pharmacist if you have any questions about taking Avidart.

Taking other medicines

Tell your doctor if you’re taking, or have recently taken, any other medicines. This includes any medicines you’ve bought without a prescription.

Some medicines can react with Avidart and may make it more likely that you’ll have side-effects. These medicines include:

•    verapamil or diltiazem (for high blood pressure)

   ritonavir or indinavir (for HIV)

•    itraconazole or ketaconazole (for fungal infections)

•    nefazodone (an antidepressant)

•    alpha-blockers (for enlarged prostate or high blood pressure).

Tell your doctor if you are taking any of these medicines.

Your dose of Avidart may need to be reduced.

Food and drink with Avidart

Avidart can be taken with or without food.

Pregnancy and breast-feeding

Women who are pregnant (or may be) must not handle leaking capsules.

Dutasteride is absorbed through the skin and can affect the normal development of a male baby. This is a particular risk in the first 16 weeks of pregnancy.

Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking Avidart. If your partner is or may be pregnant, you must avoid exposing her to your semen.

Avidart has been shown to reduce sperm count, semen volume and sperm movement. Therefore male fertility may be reduced.

Contact your doctor for advice if a pregnant woman has come into contact with dutasteride.

Driving and using machines

Avidart is unlikely to affect your ability to drive or operate machinery.

Important information about some of the ingredients of Avidart

This medicine contains lecithin from soya, which may contain soya oil. If you are allergic to peanut or soya, do not use this medicinal product.
