Dutasteride

Women of childbearing potential should not use or handle Dutasteride capsules. Dutasteride can cause birth defects in male fetuses. Dutasteride (du-TAS-tur-ide) is used to treat men who have symptoms of an enlarged prostate gland. Dutasteride blocks an enzyme called 5-alpha-reductase, which is necessary to change testosterone to another hormone that causes the prostate to grow. As a result, the size of the prostate is decreased. The effect of Dutasteride on the prostate lasts only as long as the medicine is taken. If it is stopped, the prostate begins to grow again. Dutasteride is available only with your doctor's prescription, in the following dosage forms: Oral Capsules (U.S.)

Dutasteride is used to treat an enlarged prostate (benign prostatic hyperplasia, or BPH). Dutasteride is in a class of medications called 5-alpha reductase inhibitors. It works by blocking the production of a natural substance that enlarges the prostate. This shrinks the prostate, relieves symptoms of BPH, such as frequent and difficult urination, and decreases the chance that surgery will be needed to treat this condition.

Dutasteride comes as a capsule to take by mouth. It is usually taken once a day with or without food. To help you remember to take Dutasteride, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Dutasteride exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Swallow the capsules whole; do not split, chew, or crush them.
