Dutasteride and tamsulosin tablets

Dutasteride/ tamsulosin is used for:

Treating symptoms of benign prostatic hyperplasia (BPH) in men who have an enlarged prostate gland.

Dutasteride/tamsulosin is a 5 alpha-reductase inhibitor and alpha-blocker combination. The 5 alpha-reductase inhibitor (dutasteride) works by lowering levels of a hormone called dihydrotestosterone (DHT), which is a major cause of prostate growth. The alpha-blocker (tamsulosin) works by relaxing muscles in the prostate and bladder. Dutasteride/tamsulosin helps to decrease the size of the prostate and reduce symptoms of BPH.

Do NOT use dutasteride/ tamsulosin if:

• you are allergic to any ingredient in dutasteride/tamsulosin or to other 5 alpha-reductase inhibitors (eg, finasteride)
• the patient is a woman who is pregnant or may become pregnant
• the patient is a child
• you are taking another alpha-blocker (eg, prazosin)
• you are taking certain azole antifungals (eg, itraconazole, ketoconazole, posaconazole), HIV protease inhibitors (eg, ritonavir), certain macrolide antibiotics (eg, clarithromycin), nefazodone, or telithromycin

Contact your doctor or health care provider right away if any of these apply to you.
