Dutasteride is indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to:

• Improve symptoms
• Reduce the risk of acute urinary retention
• Reduce the risk of the need for BPH-related surgery

The recommended dose is Dutasteride 0.5 mg orally once daily. The capsules should be swallowed whole. Dutasteride may be administered with or without food.

Dutasteride is contra-indicated for use in women and children and for patients with known hypersensitivity to Dutasteride, and other 5 a-reductase inhibitors. Warnings: Exposure of women-risk to male fetus: Dutasteride is absorbed through the skin. Therefore, women who are pregnant or may be pregnant should not handle Dutasteride capsules because of the possibility of absorption of Dutasteride and the potential risk of a fetal anomaly to a male fetus. If contact is made with leaking capsules, the contact area should be washed immediately with soap and water.

Side Effects

• Sexual problems (such as decreased sexual interest/ ability, decrease in the amount of semen/ sperm released during sex)
• Impotence (trouble getting or keeping an erection)
• Testicle pain or swelling
• Increased breast size
• Breast tenderness.

Overdose Effects

In volunteer studies, single doses of Dutasteride up to 40 mg (80 times the therapeutic dose) for 7 days have been administered without significant safety concerns. In a clinical study, daily doses of 5 mg (10 times the therapeutic dose) were administered to 60 subjects for 6 months with no additional adverse effects to those seen at therapeutic doses of 0.5 mg. There is no specific antidote for Dutasteride. Therefore, in cases of suspected overdosage symptomatic and supportive treatment should be given as appropriate, taking the long half-life of Dutasteride into consideration.

Lower urinary tract symptoms of BPH can be indicative of other urological diseases, including prostate cancer. Patients should be assessed to rule out other urological diseases prior to treatment with Dutasteride. Patients with a large residual urinary volume and/or severely diminished urinary flow may not be good candidates for 5 a-reductase inhibitor therapy and should be carefully monitored for obstructive uropathy. Blood Donation: Men being treated with Dutasteride should not donate blood until at least 6 months have passed following their last dose. The purpose of this deferred period is to prevent administration of Dutasteride to a pregnant female transfusion recipient.

Use in Special Populations

Pediatric use: Dutasteride is not indicated for use in the pediatric population. Safety and effectiveness in the pediatric population have not been established.

Geriatric use: No overall differences in safety or efficacy were observed between elderly and adult subjects.

Elderly use: No dosage adjustment is necessary for subjects with renal impairment or for the elderly.

Hepatic impairment: Due to the absence of data in patients with hepatic impairment, no dosage recommendation can be made.

Pregnancy & Lactation

Pregnancy Category X. Dutasteride is contraindicated for use in women.
