Uses
Dutasteride is used alone or with another medication (tamsulosin [Flomax]) to treat benign prostatic hyperplasia (BPH; enlargement of the prostate gland). Dutasteride is used to treat symptoms of BPH and may reduce the chance of developing acute urinary retention (sudden inability to urinate). Dutasteride may also decrease the chance that prostate surgery will be needed. 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.

Dutasteride Dosage
- Dutasteride comes as a capsule to take by mouth. It is usually taken once a day with or without food. Take it at 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 open chew, or crush them.
- Your symptoms may improve after you have taken dutasteride for 3 months, but it may take 6 months or longer for you to see the full benefit of dutasteride. Talk to your doctor about how you are feeling during your treatment.
- Dutasteride may control your symptoms but will not cure your condition. Continue to take it even if you feel well. Do not stop taking dutasteride without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
