Avodart Overview

Avodart (generic: dutasteride) is a prescription medication used alone or with another medication, tamsulosin (Flomax), to treat an enlarged prostate, known medically as benign prostatic hyperplasia (BPH).

Avodart belongs to a group of drugs called 5-alpha reductase inhibitors. It works by blocking the production of a natural substance that causes prostate enlargement.

This medication comes in soft gelatin capsule form and is usually taken once a day, with or without food. Avodart should be swallowed whole.

Common side effects include a decrease in sex drive (libido), trouble having or maintaining an erection (impotence), or ejaculation problems. You should not donate blood while taking Avodart or 6 months after you have stopped taking Avodart.
