It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.
Women and children should not use this medicine. Pregnant women or women who may become pregnant should not handle or touch the capsules. Dutasteride can be absorbed through the skin and can cause birth defects in male fetuses. If a pregnant woman does come in contact with this medicine, the affected area should be washed right away with soap and water, especially if the capsule is broken.
Because this medicine may cause some people to become dizzy or feel faint, make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.
Dizziness, lightheadedness, or fainting may occur after you take this medicine, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help with this problem. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.
If you plan to have cataract surgery, tell your eye doctor (ophthalmologist) that you are taking this medicine or that you used this medicine in the previous 9 months. A serious eye problem called Intraoperative Floppy Iris Syndrome (IFIS) has occurred in some patients who were taking this medicine or who had recently taken this medicine when they had cataract surgery.
This medicine may affect the results of the prostate specific antigen (PSA) test, which may be used to detect prostate cancer. Make sure you tell all of your doctors that you are using this medicine.
This medicine will not prevent prostate cancer but may increase your risk of developing high-grade prostate cancer. Tell your doctor if you have concerns about this risk.
You should seek medical attention right away if you experience a prolonged erection while using this medicine. This is an extremely rare unwanted effect that must be treated right away to prevent permanent erectile damage (impotence).
Men who have taken this medicine should not donate blood until 6 months have passed since the last dose. Dutasteride can remain in your blood for a long time and be passed on to a pregnant woman who receives a blood transfusion.
This medicine does not usually affect normal sexual abilities for most men. You may notice that you ejaculate less fluid when you have sex.
