This product is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). Dutasteride works by reducing the size of the enlarged prostate. Tamsulosin is known as an alpha-blocker and works by relaxing muscles in the bladder and prostate. This product helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate frequently or urgently (including during the middle of the night).
Dutasteride is not approved for prevention of prostate cancer. It may slightly increase the risk of developing a very serious form of prostate cancer. Talk to your doctor about the benefits and risks.
This medication should not be used by women or children.
Dizziness, lightheadedness, drowsiness, runny/stuffy nose, sexual problems (such as decreased sexual interest/ability, ejaculation problems, decrease in the amount of semen/sperm), testicle pain/swelling, increased breast size, or breast tenderness may occur. Sexual problems have continued in some men even after stopping treatment. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
