The active pharmaceutical ingredient contained in Dutas is Dutasteride. Dutas is used for treating symptoms of benign prostatic hyperplasia (BPH) or enlargement of the prostate gland. It also helps to reduce the risk of urinary blockage and the need for prostate surgery. It may also be used along with other medicines.

Dutas is a 5 alpha-reductase enzyme inhibitor. It works by lowering levels of a hormone called dihydrotestosterone (DHT), which is a major cause of prostate growth. Lowering DHT leads to shrinkage of the enlarged prostate gland.

Use Dutas  as directed by your doctor. Dutas may be taken with or without food, swallow Dutas whole. Do not break, crush, or chew before swallowing. It may take 3 to 6 months for Dutas to work. Ask your health care provider any questions you may have about how to use Dutas.

If you miss a dose of Dutas, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Check with your doctor if any of these most common side effects persist or become bothersome: breast enlargement and/or tenderness, decreased sex drive; decreased volume of ejaculate; inability to have an erection. Seek medical attention right away if any of these severe side effects occur: severe allergic reactions (rash; hives; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue).

Store Dutas between 68 and 77 degrees F (20 and 25 degrees C) in a tightly closed, light-resistant container. Store away from moisture, heat, and light. Do not store in the bathroom. Do not take tablets after the expiration date printed on the label. Keep Dutas out of the reach of children and away from pets.
